signoz_get_org_overview

Get the current status and overall posture of the SigNoz deployment before drilling into exact resources. data.sourceStats is the authoritative complete flat bag containing every key and value reported by the deployment stats endpoint, including current and future fields. Typed convenience projections cover telemetry freshness and volume, infrastructure presence, dashboards, alert rules and runtime, notification channels, saved views, log pipelines, cloud integrations, users, authentication, service accounts, roles, licensing, and configuration.

• Parameters: no task parameters; like every tool, it accepts non-required searchContext for MCP observability.
• Authoritative source: sourceStats preserves every successfully decoded entry from the upstream data object under its original dotted key. Use the grouped fields for convenient interpretation and sourceStats when exact backend coverage or a newly introduced field matters. Counts are deployment aggregates; use signoz_list_dashboards, signoz_list_alert_rules, signoz_list_notification_channels, or signoz_list_views for exact inventories; signoz_list_metrics for metric names; signoz_list_alerts for current alert instances; and signoz_search_logs, signoz_search_traces, or signoz_query_metrics for time-windowed or per-service data.
• Missing fields: a key absent from sourceStats was not reported by the upstream collector and must not be interpreted as zero. The endpoint can return a partial HTTP 200 when an individual collector fails. In typed projections, a missing group total produces available: false; a reported zero produces available: true. Expected missing or invalid projection fields set metadata.projectionPartial and add an incompleteGroups entry with affected output paths, reason, next action, and exact fallback tools where available. An invalid projection value is still retained unchanged in sourceStats and named in invalidProjectionFields.
• Cloud-integration completeness: cloudIntegrations.sourceAvailability reports whether both current AWS/Azure provider counts were reported. Each provider has its own dataAvailable; an absent provider count is never converted to zero. If neither provider is reported, source availability is unavailable without setting overall metadata.projectionPartial; this can mean cloud integrations are unsupported/edition-gated or both provider queries failed, so do not interpret it as “no cloud integrations configured.” If exactly one is reported, source availability is partial and the missing provider receives non-recursive recovery guidance. connectedAccounts means a non-removed account with an account ID and at least one agent report, not a recent check-in or proof that an integration service is enabled.
• Projection metadata: reportedStatCount is the number of authoritative entries in sourceStats; projectedStatCount counts entries also represented in typed groups; and unprojectedStatCount counts entries available only in sourceStats, including future fields. projectionPartial, incompleteGroups, and invalidProjectionFields describe only typed-projection gaps; they do not indicate data was removed from sourceStats or claim endpoint-wide completeness.

signoz_list_metrics

Discover metric names and catalog metadata such as type, temporality, unit, and monotonicity. Use signoz_query_metrics for values or trends. This list has a limit but no offset pagination.

• Parameters:
  • searchText (optional) - Filter metrics by name substring (e.g., 'cpu', 'memory')
  • limit (optional) - Maximum number of metrics to return (default: 50)
  • timeRange (optional) - Relative range: 30m, 1h, 6h, 24h, 7d (default: 1h; ignored when both start and end are provided)
  • start/end (optional) - Unix ms timestamps. When both are provided, they override timeRange.
  • source (optional) - Data-source filter. Use "meter" to list Cost Meter metrics, the usage/billing metrics SigNoz meters on (currently telemetry ingestion volume); omit for the default metrics store
  • Completeness note: the response appends a note reporting hasMore (inferred from returnedRows == limit) so a limit-truncated list is never mistaken for the full set; narrow with searchText for more specificity

signoz_query_metrics

Query a known metric for values, trends, breakdowns, or formulas. The tool applies metric-aware defaults and auto-fetches omitted metadata; call it directly when metricName is known. Use signoz_list_metrics only to discover a name or inspect catalog metadata.

• Parameters:
  • metricName (required) - Metric name to query
  • metricType (optional) - gauge, sum, histogram, exponential_histogram (auto-fetched if absent)
  • isMonotonic (optional) - Boolean (or the strings "true"/"false"); auto-fetched if absent. An invalid value is rejected rather than silently treated as false
  • temporality (optional) - cumulative, delta, unspecified (auto-fetched if absent)
  • timeAggregation (optional) - Aggregation over time (auto-defaulted by type)
  • spaceAggregation (optional) - Aggregation across dimensions (auto-defaulted by type)
  • groupBy (optional) - Comma-separated field names or an array. Resource context is inferred for k8s.*, container.*, host.*, cloud.*, deployment.*, process.*, service.*, telemetry.*, and os.*; other names use attribute context
  • filter (optional) - Filter expression
  • timeRange (optional) - Relative time range <number><unit> where unit is m/h/d (e.g. '30m', '1h', '6h', '7d'; default: '1h'; ignored when both start and end are provided)
  • start/end (optional) - Unix ms timestamps. When both are provided, they override timeRange.
  • stepInterval (optional) - Step in seconds (auto-calculated if omitted)
  • requestType (optional) - Response format. Enum: time_series (default), scalar. Unknown values are rejected.
  • reduceTo (optional) - For scalar: sum, count, avg, min, max, last, median
  • formula (optional) - Expression over named queries (e.g., "A / B * 100")
  • formulaQueries (optional) - Array or JSON-encoded array string of additional named metric queries for formula. Each object supports name, metricName, metricType, isMonotonic, temporality, timeAggregation, spaceAggregation, groupBy, and filter; name and metricName are required.
  • source (optional) - Data-source filter. Use "meter" to query Cost Meter data; omit for the default metrics store
  • Result bounds: standalone generated metric queries and formula results use limit: 100 with __result desc. Every query feeding a formula uses limit: 10000, because component limits are applied before formula evaluation and independent top-100 inputs can discard a high-ratio group. The response decisions note reports both bounds. Narrow the filters/grouping when formula-input cardinality can exceed 10000.
  • Key-not-found errors: a filter referencing a key absent from this workspace's metrics metadata fails with recovery guidance in the error text plus a machine-readable missingKeys array in the structured error content

signoz_get_top_metrics

Return top 100 metrics ranked by ingested sample volume with pre-computed percentages. Use this to identify which metrics are driving the most ingestion volume and cost. Wraps POST /api/v2/metrics/treemap. Response fields: metricName, percentage (share of total sample volume), totalValue (absolute sample count).

• Parameters:
  • timeRange (optional) - Relative time range <number><unit> where unit is m/h/d (e.g. '1h', '24h', '3d', '7d', '30d'; default: '7d'; ignored when both start and end are provided). Start with 7d; if the query times out, retry with 3d, then 24h
  • start/end (optional) - Unix ms timestamps. When both are provided, they override timeRange
  • Completeness note: returns a fixed top 100 by ingested sample volume; the response appends a note flagging whether the list was truncated at that cap (hasMore)

signoz_check_metric_usage

Given a list of metric names, return which dashboards and alerts reference each one. Wraps /api/v3/metrics/dashboards?metricName=... and /api/v2/metrics/alerts?metricName=... per metric. Dashboard usage needs SigNoz v0.135.0 (the v3 route reads v2/Perses dashboards, live in v0.135.0; older versions return empty dashboards); alert usage works from v0.131.0.

• Parameters:
  • metricNames (required) - Array of metric name strings to check (max 50 per call). Example: ["system.disk.io", "k8s.node.condition"]. For larger lists, split into batches of 50 and merge results.
• Response: per metric, dashboards (list of dashboard names that reference the metric), alerts (list of alert names that reference the metric), error (non-empty when the lookup failed; do not treat the metric as unused in that case)
• Limits: Maximum 50 metrics per call; 30-second overall timeout (partial results returned on expiry)

signoz_check_metric_cardinality

Return label/attribute keys for one metric with cardinality counts and sample values, sorted highest first. Samples help distinguish unbounded values such as UUIDs from bounded dimensions such as status codes. This tool does not show whether the metric is used; call signoz_check_metric_usage before recommending a drop.

• Parameters:
  • metricName (required) - Metric name to inspect. Example: k8s.container.memory_limit
  • timeRange (optional) - Relative time range <number><unit> where unit is m/h/d (e.g. '30m', '1h', '6h', '24h', '3d', '7d'; default: '7d'; ignored when both start and end are provided)
  • start/end (optional) - Unix ms timestamps. When both are provided, they override timeRange

signoz_list_alerts

Lists currently firing/silenced/inhibited alert instances from Alertmanager, not rule definitions. Use signoz_list_alert_rules for configured rules, signoz_get_alert with an id for one full rule definition, or signoz_get_alert_history for the state timeline.

• Parameters:
  • limit (optional) - Maximum number of alerts per page (default: 50)
  • offset (optional) - Number of results to skip for pagination (default: 0)
  • active / silenced / inhibited (optional) - Tri-state filters. Boolean (or the strings "true"/"false"). Omit to defer to the backend default (all states included). An invalid value is rejected rather than silently dropped
  • filter (optional) - Comma-separated alert-label comparisons using =, !=, =~ (regex), or !~ (negative regex), e.g. alertname="HighCPU",severity="critical"
  • receiver (optional) - Regex to filter alerts by receiver name

signoz_list_alert_rules

Lists configured alert-rule summaries from GET /api/v2/rules, including inactive/OK and disabled rules. Use signoz_get_alert for one full definition; use signoz_list_alerts for current Alertmanager instances.

• Parameters:
  • limit (optional) - Maximum number of rules to return per page (default: 50, max: 1000; higher values are clamped)
  • offset (optional) - Number of rules to skip for pagination (default: 0)

signoz_get_alert

Gets one alert rule's full definition (GET /api/v2/rules/{id}). Use signoz_list_alert_rules to discover IDs. Before signoz_update_alert, call this only when a complete current definition is not already available for the prepared operation; reuse a still-current result and preserve unchanged fields.

• Parameters: id (required) - Alert rule ID (UUIDv7 on v2-capable servers).
• Note: Response shape depends on the SigNoz server version. Post-#10997 servers return the canonical Rule type with createdAt/updatedAt/createdBy/updatedBy; older servers return GettableRule with createAt/updateAt/createBy/updateBy (no 'd').

signoz_list_dashboards

Lists paginated tenant-dashboard summaries (name, UUID, description, tags, timestamps). Use signoz_get_dashboard for panel and query definitions, and page by raising offset by limit until you have covered total before concluding a dashboard is absent.

• Parameters:
  • limit (default 50), offset (default 0) – offset-based pagination
  • filter (optional) – server-side filter DSL over dashboard metadata (name, description, tags, creator, timestamps, locked state)
  • sort (optional) – updated_at (default), created_at, or name
  • order (optional) – asc or desc (default desc)

The filter DSL is a boolean expression of key operator value terms and bare free-text words joined with AND/OR/NOT and parentheses (e.g. name CONTAINS 'overview' AND locked = true). Read signoz://dashboard/list-filter-guide for the full grammar, the filterable keys with their operators, value formats, and worked examples; the list response also echoes the authoritative reserved-key set in reservedKeywords.

signoz_get_dashboard

Gets one known tenant dashboard's complete layout, variables, panels, and queries. Use signoz_list_dashboards to discover the UUID.

• Parameters: id (required) - Dashboard UUID

signoz_create_dashboard

Creates a custom multi-panel dashboard. Use signoz_import_dashboard when a curated template fits, or signoz_create_view to save one Explorer query. Read signoz://dashboard/instructions, signoz://dashboard/widgets-instructions, and signoz://dashboard/widgets-examples before composing the payload.

• Parameters:
  • schemaVersion (required) – Must be "v6"
  • name (DNS-1123 label) or generateName: true to derive it from spec.display.name
  • tags (required) – Array of key/value tags (may be empty)
  • spec (required) – Perses spec: display, variables (array), panels (map keyed by panel id), layouts (array)

signoz_import_dashboard

Creates a dashboard from a curated template hosted in the SigNoz/dashboards repo (main branch). The server fetches the template JSON and creates the dashboard in one call.

When the relative template path is unknown, call signoz_list_dashboard_templates first. Pass its path, not a URL or absolute path.

• Parameters:
  • path (required) – Template path within the SigNoz/dashboards repo, e.g. hostmetrics/hostmetrics.json

signoz_list_dashboard_templates

Returns the full bundled catalog of curated SigNoz dashboard templates as {"templates": [...], "total": N}, where each entry has id, title, path, description, category, and keywords. It does not list dashboards already created in the tenant; use signoz_list_dashboards for those.

• Parameters: none

signoz_update_dashboard

Fully replaces an existing dashboard. Fetch it with signoz_get_dashboard, take the data object out of that response, merge only the requested changes into it, and send that object's fields at the top level, preserving every other field. The {status, data} response envelope is not accepted as input. Use signoz_update_view for a saved Explorer query.

• Parameters:
  • id (required) – Dashboard id (the legacy uuid key is also accepted)
  • schemaVersion, name, tags, spec – the complete post-update state (see the tool's JSON Schema)

signoz_patch_dashboard

Applies an RFC 6902 JSON Patch to a dashboard: a partial update without re-sending the entire dashboard. Prefer this over signoz_update_dashboard for targeted edits (rename, add/edit one panel or query, tweak a variable). Read signoz://dashboard/patch-instructions for worked recipes and exact paths; notably, adding a panel needs two ops (the panel plus its grid item) or it won't render.

• Parameters:
  • id (required) – Dashboard id (the legacy uuid key is also accepted)
  • patch (required) – Array of {op, path, value} operations; paths are JSON Pointers into the dashboard's postable shape, e.g. /spec/display/name, /spec/panels/<panelId>, /spec/layouts/0/spec/items/-, /tags/-

signoz_list_services

Lists paginated APM services with trace activity in a time range. Absence means no trace activity in that window, not that the same service.name never appears in logs; use signoz_get_field_values with signal="logs" for log values.

• Parameters:
  • timeRange (optional) - Relative time range <number><unit> where unit is m/h/d (e.g. '30m', '1h', '6h', '7d'; defaults to last 6 hours; ignored when both start and end are provided)
  • start (optional) - Start time in unix milliseconds (defaults to 6 hours ago).
  • end (optional) - End time in unix milliseconds (defaults to now)
  • limit (optional) - Maximum services per page (default: 50, max: 1000; higher values are clamped)
  • offset (optional) - Number of results to skip for pagination (default: 0)

signoz_get_service_top_operations

Gets the built-in operation table for one traced service, ranked by p99 latency with each operation's p50, p95, p99, call count, and error count. Use signoz_aggregate_traces for custom aggregation, grouping, time series, cross-service comparison, or arbitrary trace filters.

• Parameters:
  • service (required) - Exact traced service name, typically from signoz_list_services
  • timeRange (optional) - Relative time range <number><unit> where unit is m/h/d (e.g. '30m', '1h', '6h', '7d'; defaults to last 6 hours; ignored when both start and end are provided)
  • start (optional) - Start time in unix milliseconds (defaults to 6 hours ago).
  • end (optional) - End time in unix milliseconds (defaults to now)
  • tags (optional) - JSON-encoded TagQueryParam array passed as a string, for example [{"key":"http.method","tagType":"SpanAttribute","operator":"In","stringValues":["GET"]}]; omit for no tag filter

signoz_get_alert_history

Gets one configured rule's firing or state-transition history. Defaults to the last 6 hours. Use state and filter to narrow results. For the next page, pass data.nextCursor as cursor and repeat the original filters, time range, and order.

The response is { "status": "success", "data": { "items": [...], "total": <n>, "nextCursor": "<opaque>" } }; nextCursor is omitted on the final page.

• Parameters:
  • id (required) - Alert rule ID from signoz_list_alert_rules
  • timeRange (optional) - Relative time range <number><unit> where unit is m/h/d (e.g. '30m', '1h', '6h', '7d'; defaults to last 6 hours; ignored when both start and end are provided)
  • start (optional) - Start timestamp in unix milliseconds (defaults to 6 hours ago).
  • end (optional) - End timestamp in unix milliseconds (defaults to now)
  • state (optional) - Filter by alert state. Enum: inactive, pending, recovering, firing, nodata, disabled (omit for all transitions)
  • filter (optional) - SigNoz query-builder expression over timeline labels. Combine conditions with AND, OR, and parentheses; quote strings with single quotes. Example: severity = 'critical' AND (team = 'payments' OR service.name = 'checkout'). To discover keys, first call without a filter and inspect data.items[].labels[].key.name. The backend-shaped filterExpression alias remains accepted for compatibility, but filter is canonical.
  • cursor (optional) - Opaque continuation cursor. Repeat the original time range, state, filter, and order when fetching the next page. Omit cursor for the first page.
  • limit (optional) - Rows per page. Default: 20; max: 10000 (higher values are clamped).
  • order (optional) - Sort order. Enum: asc, desc (default: 'asc')
  • Legacy offset: no longer supported; use the returned cursor instead.
  • Completeness note: the response appends a note reporting hasMore from data.nextCursor and names the cursor for the next page.

Requires SigNoz ≥ v0.118.0, the first release to serve the v2 rule-history routes (/api/v2/rules/{id}/history/*, added in SigNoz #10488). If this tool returns NOT_FOUND, verify the rule id in the SigNoz UI or, on SigNoz v0.120.0+, with signoz_list_alert_rules; if the rule exists, upgrade SigNoz. Earlier deployments only expose the v1 POST /api/v1/rules/{id}/history/timeline.

signoz_list_views

List saved Explorer views or discover a view UUID for one Logs, Traces, Metrics, Cost Meter, or AI Observability page. A view stores one reusable Explorer query spec; it is not a multi-panel dashboard. Apply name filters before pagination and follow pagination.nextOffset while pagination.hasMore is true.

• Parameters:
  • source (required) - One of: traces, logs, metrics, meter. Cost Meter views are filed under meter (a distinct Explorer page), not metrics
  • name (optional) - Partial-match filter on view name (server-side)
  • limit (optional) - Page size (default: 50, max: 1000; higher values are clamped)
  • offset (optional) - Number of results to skip (default: 0)

Requires SigNoz ≥ v0.137.0, the first release to serve the v2 saved-view routes (/api/v2/saved_views/*; SigNoz #12342). Earlier deployments only expose the legacy GET /api/v1/explorer/views.

signoz_get_view

Get one saved Explorer view's complete definition by UUID. Call this before signoz_update_view, which fully replaces the view.

• Parameters: id (required) - Saved view UUID

signoz_search_docs

Search official SigNoz documentation and return ranked pages with URLs and snippets for product, setup, instrumentation, configuration, API, deployment, or troubleshooting questions. Send 2 to 6 keywords for one topic and keep product and technology names as the user wrote them; split multi-intent questions into separate calls. If the top result is off-topic, retry with fewer or different terms. Do not use for live tenant data; use signoz_fetch_doc for the full content of a selected result or exact docs URL.

• Parameters:
  • searchText (required) - 2 to 6 keywords for one topic, for example "Kubernetes pod logs". Keep product and technology names as the user wrote them.
  • limit (optional) - Maximum results to return as a string (default: 10, max: 25; a numeric value is also accepted). The 25 ceiling is deliberate: each result hydrates document text out of the in-process docs index, so a larger limit inflates this server's resident memory.
  • section_slug (optional) - Exact top-level docs section filter, such as setup, logs-management, apm-distributed-tracing, metrics, alerts, dashboards, signoz-apis, querying, or collection-agents. Reuse the section_slug from an earlier result when narrowing; an unknown slug returns zero results
  • searchContext - User's original question

Docs search telemetry counts executed searches in signoz_docs_searches_total with outcome=ok|error. Only successful searches have result_count_bucket (0, 1-4, 5-9, or 10+). signoz_docs_search_top_score records the top hit's raw Bleve score only for successful non-empty searches. Scores are uncalibrated and depend on query terms, boosts, and analyzer settings; they are not relevance probabilities or thresholds. Search spans record mcp.docs.search_text (the executed query, truncated to 256 Unicode runes), mcp.docs.section_slug, and mcp.docs.result_count. Successful non-empty searches also record mcp.docs.top_score. These span attributes distinguish the client's keyword query from the user's original request in mcp.search_context; query text is not a metric attribute. If the query is invalid Bleve query-string syntax, search drops that clause, continues with text matching, and records mcp.docs.query_string_dropped=true. Empty or whitespace-only queries remain validation errors.

signoz_fetch_doc

Fetch one known official SigNoz docs page's full Markdown or a requested heading. Use signoz_search_docs to discover a page first; accepted inputs are https://signoz.io/docs/... URLs or /docs/... paths.

• Parameters:
  • url (required) - Docs page URL or path
  • heading (optional) - Heading anchor ID or heading text
  • searchContext - User's original question

signoz_create_view

Save one reusable Explorer query spec. Use signoz_create_dashboard for a multi-panel dashboard. Cost Meter views use source="meter" with signal="metrics" and builder-spec source="meter".

• Parameters (v2 typed shape):
  • name (optional) - View name (DNS-1123 label). Required unless generateName is true
  • generateName (optional) - When true, the server generates name from spec.displayName and name must be empty
  • source (required) - Which Explorer this view belongs to
  • spec (required) - Typed view content: displayName, panelType, requestType, queries, selectedFields, display
  • schemaVersion (optional) - Always v2; defaults when omitted
• Required: Read both MCP resources signoz://view/instructions and signoz://view/examples before composing any payload.

signoz_update_view

Fully replace an existing saved Explorer view. Fetch it with signoz_get_view, modify its returned data object, preserve every unrequested field, and pass that full object as view. Upstream keeps name immutable on update; the display label lives in spec.displayName.

• Parameters:
  • id (required) - UUID of the view to replace
  • view (required) - Full source/spec pair (required); drop name and server-populated fields
• Resource rule: Read signoz://view/instructions and signoz://view/examples when changing source or spec. Skip them for a pass-through of the fetched body. Call signoz_get_view first; partial bodies wipe unspecified fields.

signoz_delete_view

Permanently delete a confirmed saved Explorer view by UUID. Use signoz_list_views to discover the ID; use signoz_delete_dashboard for a dashboard.

• Parameters: id (required) - Saved view UUID

signoz_aggregate_logs

Return aggregate statistics over logs (counts, rates, averages, percentiles, or grouped/top-N breakdowns) rather than individual records. Use signoz_search_logs for log rows and message inspection.

• Parameters:
  • aggregation (required) - Aggregation function: count, count_distinct, avg, sum, min, max, p50, p75, p90, p95, p99, rate
  • aggregateOn (optional) - Field to aggregate on (required for all except count and rate)
  • groupBy (optional) - Comma-separated fields to group by (e.g., 'service.name, severity_text')
  • filter (optional) - Filter expression using SigNoz search syntax. Combine conditions with AND, OR, and parentheses. Unknown keys hard-error; ambiguous keys default to resource context. Log keys are workspace-specific; even service.name is only present when the log pipeline sets it. See signoz://logs/query-builder-guide
  • service (optional) - Shortcut filter for service name (adds service.name = '<value>'; fails with key service.name not found when the workspace's logs lack that attribute)
  • severity (optional) - Exact severity_text; DEBUG, INFO, WARN, ERROR, and FATAL are common examples, not an exhaustive enum. Discover values with signoz_get_field_values(signal="logs", name="severity_text", fieldContext="log")
  • orderBy (optional) - Order expression and direction (e.g., 'count() desc')
  • limit (optional) - Maximum number of groups to return (default: 100, max: 10000; higher values are clamped to bound server memory)
  • timeRange (optional) - Relative time range <number><unit> where unit is m/h/d (e.g. '30m', '1h', '6h', '24h', '7d'; default: '1h'; ignored when both start and end are provided)
  • start / end (optional) - Start/end time in unix milliseconds. When both are provided, they override timeRange.
  • requestType (optional) - scalar (default; one aggregate value over the whole range) or time_series (one value per time bucket). Unknown values are rejected.
  • stepInterval (optional) - Time bucket size in seconds for time_series mode. Accepts a number or numeric string (backend auto-selects when omitted)
  • Time-series ranking note: the limit selects top groups over the whole requested window, not independently per bucket. Narrow the window or adjust the limit when a short-lived series could otherwise be hidden.
  • Key-not-found errors: a filter referencing a key absent from this workspace's logs metadata fails with recovery guidance in the error text plus a machine-readable missingKeys array in the structured error content

signoz_search_logs

Return individual paginated log records matching text, service, severity, or field filters. Use signoz_aggregate_logs for counts, trends, or grouped breakdowns.

Calls using only searchText, service, severity, time, or pagination parameters need no guide read. Read signoz://logs/query-builder-guide only before composing filter with unfamiliar workspace fields.

• Parameters:
  • filter (optional) - Filter expression using SigNoz search syntax. Combine conditions with AND, OR, and parentheses (e.g., "(severity_text = 'ERROR' OR body CONTAINS 'panic') AND service.name = 'payment-svc'"). Log keys are workspace-specific; even service.name is only present when the log pipeline sets it. Legacy query is still accepted for backward compatibility, but filter is canonical. See signoz://logs/query-builder-guide
  • service (optional) - Service name to filter by (adds service.name = '<value>'; fails with key service.name not found when the workspace's logs lack that attribute)
  • severity (optional) - Exact severity_text; DEBUG, INFO, WARN, ERROR, and FATAL are common examples, not an exhaustive enum. Discover values with signoz_get_field_values(signal="logs", name="severity_text", fieldContext="log")
  • searchText (optional) - Text to search for in log body (uses CONTAINS matching)
  • timeRange (optional) - Relative time range <number><unit> where unit is m/h/d (e.g. '30m', '1h', '6h', '24h', '7d'; default: '1h'; ignored when both start and end are provided)
  • start / end (optional) - Start/end time in unix milliseconds. When both are provided, they override timeRange.
  • limit (optional) - Maximum number of logs to return (default: 100, max: 10000; higher values are clamped; paginate with offset)
  • offset (optional) - Offset for pagination (default: 0)
  • Ordering: generated raw log queries use timestamp desc, then id desc, so offset pagination is deterministic when multiple rows share a timestamp.
  • Completeness note: the response appends a note reporting hasMore (inferred from returnedRows == limit) and the nextOffset to fetch, so a truncated page is never mistaken for the full result set
  • Key-not-found errors: a filter referencing a key absent from this workspace's logs metadata fails with recovery guidance in the error text plus a machine-readable missingKeys array in the structured error content

signoz_get_field_keys

Discover field names available for filtering or grouping metrics, traces, or logs. This returns keys, not observed values; use signoz_get_field_values after selecting a key.

• Parameters:
  • signal (required) - Signal type. Enum: metrics, traces, logs
  • searchText (optional) - Filter field keys by name substring
  • metricName (optional) - Filter by metric name (relevant for metrics signal)
  • fieldContext (optional) - Restrict to a field context: resource, attribute (alias tag), scope, log/span/metric (intrinsic/built-in columns), or body (JSON log body). Distinguishes intrinsic columns from user attributes.
  • fieldDataType (optional) - Restrict to a data type: string, bool, int64, float64, number, or array forms like []string
  • source (optional) - For metrics, use meter for Cost Meter fields; omit for the default metrics store

signoz_get_field_values

Get observed values for a known field key. Use signoz_get_field_keys when the key is unknown, and match signal and fieldContext to the query that will use the value.

• Parameters:
  • signal (required) - Signal type. Enum: metrics, traces, logs
  • name (required) - Field key name to get values for (e.g., service.name, http.method)
  • searchText (optional) - Filter values by substring
  • metricName (optional) - Filter by metric name (relevant for metrics signal)
  • fieldContext (optional) - Restrict the lookup to a field context (resource, attribute/tag, scope, log/span/metric, body) when the same key name exists in more than one
  • source (optional) - For metrics, use meter for Cost Meter values; omit for the default metrics store

signoz_search_traces

Return individual paginated span rows matching service, operation, error, duration, or field filters, and use them to discover trace IDs. Use signoz_aggregate_traces for statistics or signoz_get_trace_details for one known trace.

• Parameters:
  • filter (optional) - Filter expression using SigNoz search syntax. Combine conditions with AND, OR, and parentheses (e.g., "service.name = 'payment-svc' AND (has_error = true OR attribute.http.response.status_code >= 500)"). Legacy query is still accepted for backward compatibility, but filter is canonical. See signoz://traces/query-builder-guide
  • service (optional) - Service name to filter by
  • operation (optional) - Operation/span name to filter by
  • error (optional) - Filter by error status. Boolean (or the strings "true"/"false"). An invalid value is rejected rather than silently dropped
  • minDuration / maxDuration (optional) - Min/max span duration in nanoseconds (e.g., '500000000' for 500ms)
  • timeRange (optional) - Relative time range <number><unit> where unit is m/h/d (e.g. '30m', '1h', '6h', '24h', '7d'; default: '1h'; ignored when both start and end are provided)
  • start / end (optional) - Start/end time in unix milliseconds. When both are provided, they override timeRange.
  • limit (optional) - Maximum span rows to return (default: 100, max: 10000; higher values are clamped; paginate with offset)
  • offset (optional) - Number of span rows to skip (default: 0)
  • Ordering: generated raw trace queries use timestamp desc.
  • Completeness note: the response appends a note reporting hasMore (inferred from returnedRows == limit) and the nextOffset to fetch, so a truncated page is never mistaken for the full result set
  • Output note: raw result row keys follow canonical Query Builder field names (for example trace_id, span_id, duration_nano, has_error). Legacy caller-provided filters such as hasError still pass through to the backend alias layer, but new response parsers should read the canonical snake_case keys.
  • Key-not-found errors: a filter referencing a key absent from this workspace's traces metadata fails with recovery guidance in the error text plus a machine-readable missingKeys array in the structured error content

signoz_aggregate_traces

Return custom aggregate statistics over spans (counts, rates, latency percentiles, grouped/top-N breakdowns, or time series) rather than individual rows or a full trace hierarchy. For one traced service's built-in operation table ranked by p99, use signoz_get_service_top_operations. Read signoz://traces/query-builder-guide before calling this tool.

• Parameters:
  • aggregation (required) - Aggregation function: count, count_distinct, avg, sum, min, max, p50, p75, p90, p95, p99, rate
  • aggregateOn (optional) - Field to aggregate on (e.g., 'duration_nano'). Required for all except count and rate
  • groupBy (optional) - Comma-separated fields to group by (e.g., 'service.name, name')
  • filter (optional) - Filter expression using SigNoz search syntax. Combine conditions with AND, OR, and parentheses. Unknown keys hard-error; ambiguous keys default to resource context. See signoz://traces/query-builder-guide
  • service (optional) - Shortcut filter for service name
  • operation (optional) - Shortcut filter for span/operation name
  • error (optional) - Shortcut filter for error spans. Boolean (or the strings "true"/"false"). An invalid value is rejected rather than silently dropped
  • orderBy (optional) - Order expression and direction (e.g., 'avg(duration_nano) desc')
  • limit (optional) - Maximum number of groups to return (default: 100, max: 10000; higher values are clamped to bound server memory)
  • timeRange (optional) - Relative time range <number><unit> where unit is m/h/d (e.g. '30m', '1h', '6h', '24h', '7d'; default: '1h'; ignored when both start and end are provided)
  • start / end (optional) - Start/end time in unix milliseconds. When both are provided, they override timeRange.
  • requestType (optional) - scalar (default; one aggregate value over the whole range) or time_series (one value per time bucket). Unknown values are rejected.
  • stepInterval (optional) - Time bucket size in seconds for time_series mode. Accepts a number or numeric string (backend auto-selects when omitted)
  • Time-series ranking note: the limit selects top groups over the whole requested window, not independently per bucket. Narrow the window or adjust the limit when a short-lived series could otherwise be hidden.
  • Key-not-found errors: a filter referencing a key absent from this workspace's traces metadata fails with recovery guidance in the error text plus a machine-readable missingKeys array in the structured error content

signoz_get_trace_details

For a known trace ID, return its spans, metadata, and hierarchy. Use signoz_search_traces first when the ID is unknown, and choose a time window that contains the trace; the default last six hours can miss older traces.

• Parameters:
  • traceId (required) - Known trace ID, usually discovered with signoz_search_traces
  • timeRange (optional) - Relative time range <number><unit> where unit is m/h/d (e.g. '30m', '1h', '6h', '7d'; defaults to last 6 hours; ignored when both start and end are provided)
  • start (optional) - Start time in unix milliseconds (defaults to 6 hours ago).
  • end (optional) - End time in unix milliseconds (defaults to now)
  • includeSpans (optional) - Include detailed span information. Boolean (or the strings "true"/"false"), default: true

signoz_create_alert

Create a new alert rule in SigNoz via POST /api/v2/rules.

• Parameters: JSON payload matching the SigNoz alert rule schema.
• Schema varies by ruleType:
  • threshold_rule / promql_rule → v2alpha1 (structured condition.thresholds, evaluation, notificationSettings).
  • anomaly_rule → v1, metrics only: top-level evalWindow/frequency, condition anomaly fields, and direct top-level preferredChannels. Omit thresholds, evaluation, notificationSettings, and schemaVersion; policy routing is unsupported.
• Notification routing: For direct routing, reuse a fully paginated signoz_list_notification_channels result only from the same still-current prepared operation; otherwise call it, refreshing only if state may have changed. V2 needs an exact returned name on every tier and rejects top-level preferredChannels; v1 anomaly uses direct top-level preferredChannels. If none fits, ask the user or offer signoz_create_notification_channel with user-provided config; never create automatically. Confirmed v2 policy routing may omit tier channels; supplied names are still validated.
• Tip: Reuse alert resources only when already read for the same prepared operation; otherwise read signoz://alert/instructions and signoz://alert/examples. For PromQL, read signoz://promql/instructions when needed.

signoz_update_alert

Update an existing alert rule via PUT /api/v2/rules/{id}. This fully replaces the rule: reuse signoz_get_alert, signoz://alert/instructions, signoz://alert/examples, and fully paginated signoz_list_notification_channels results only from the same still-current prepared operation; otherwise read/call them, refreshing only if state may have changed, then preserve unchanged fields. Direct v2 needs an exact listed name on every tier; confirmed v2 policy routing may omit them. V1 anomalies use direct top-level preferredChannels and cannot use policy routing.

• Parameters:
  • id (required) - UUIDv7 of the rule to update (obtain from signoz_list_alert_rules / signoz_get_alert).
  • Plus all fields of the alert rule schema (same shape as signoz_create_alert).

signoz_delete_alert

Delete an alert rule via DELETE /api/v2/rules/{id}. Irreversible: discover the ID with signoz_list_alert_rules and confirm the exact rule first. When both steps are already complete, call the delete tool directly without repeating list/get preflight.

• Parameters:
  • id (required) - UUIDv7 of the rule to delete. The server rejects non-UUIDv7 values with invalid_input.

signoz_delete_dashboard

Permanently delete a confirmed tenant dashboard by ID. The deletion is irreversible; use signoz_list_dashboards to discover the UUID. Use signoz_delete_view for a saved Explorer view.

• Parameters: id (required) - Dashboard UUID to delete

signoz_list_notification_channels

List paginated notification-channel summaries (id, name, type, timestamps). Use this to verify alert channel names, avoid duplicate channel names, or discover an ID. It does not return provider-specific settings; use signoz_get_notification_channel for those.

• Parameters:
  • limit (optional) - Maximum number of channels to return per page (default: 50, max: 1000; higher values are clamped)
  • offset (optional) - Offset for pagination (default: 0)

signoz_create_notification_channel

Create a notification channel and send a test notification. First call signoz_list_notification_channels and confirm the requested name is unused.

• Parameters:
  • type (required) - Channel type: slack, webhook, pagerduty, email, opsgenie, msteams
  • name (required) - Unique channel name, verified against signoz_list_notification_channels
  • send_resolved (optional) - Send notifications when alerts resolve. Boolean (or the strings "true"/"false"), default: true
  • Type-specific fields (required by channel type), such as slack_api_url, webhook_url, pagerduty_routing_key, email_to, opsgenie_api_key, or msteams_webhook_url
• Test-send behavior: the channel is created first, then a test notification is sent. If the test fails, the tool still returns success (the channel WAS created) but appends a prominent warning note so the failure is not buried; verify the configuration and re-test.

signoz_update_notification_channel

Fully replace an existing notification channel and send a test notification. First find the ID with signoz_list_notification_channels, fetch the complete configuration with signoz_get_notification_channel, then preserve every field not requested for change.

• Parameters:
  • id (required) - Notification channel UUID
  • type (required) - Channel type
  • name (required) - Channel name
  • send_resolved (optional) - Complete replacement setting. Copy the fetched value unless changing it; omission resets to true
  • Full channel configuration fields for the selected channel type
• Test-send behavior: same as create: a failed verification test-send surfaces a prominent warning note instead of flipping the result to an error.

signoz_get_notification_channel

Get all provider-specific settings for one notification channel by ID (GET /api/v1/channels/{id}). Use signoz_list_notification_channels to discover IDs.

• Parameters:
  • id (required) - Notification channel UUID

signoz_delete_notification_channel

Delete a notification channel by ID (DELETE /api/v1/channels/{id}). Irreversible: resolve its ID and confirm the exact channel first. When both steps are already complete, call the delete tool directly without repeating list/get preflight. This tool does not check whether alert rules reference it; inspect configured rules first when dependency safety is required.

• Parameters:
  • id (required) - Notification channel UUID

signoz_execute_builder_query

Runs a SigNoz Query Builder v5 request that the dedicated tools cannot express, including multi-query requests, formulas, PromQL, and ClickHouse SQL. Prefer signoz_search_logs / signoz_search_traces for rows, signoz_aggregate_logs / signoz_aggregate_traces for grouped results, and signoz_query_metrics for ordinary metrics.

• Parameters: query (required) - Complete SigNoz Query Builder v5 JSON object
• Query types: the per-envelope compositeQuery.queries[i].type selects the spec shape:
  • builder_query: signal-specific spec (logs/traces/metrics) with filter, aggregations, groupBy, etc.
  • builder_formula: formula expression referencing other query names (e.g. A / B * 100).
  • promql: {name, query, disabled, step?, legend?}. PromQL for OTel metrics requires the Prometheus 3.x UTF-8 quoted-selector form {"metric.name.with.dots"}; read the signoz://promql/instructions resource for details.
  • clickhouse_sql: {name, query, disabled, legend?}.
• Builder result bounds: for predictable authored queries, explicitly supply a positive spec.limit and non-empty v5 spec.order (not dashboard/editor orderBy) on every builder_query and builder_formula. When omitted, null, or zero, standalone limits and formula-result limits default to 100; a builder query referenced by a formula defaults to 10000 because base-query limits are applied before formula evaluation. Raw logs order by timestamp desc, id desc; raw traces by timestamp desc; metric scalar/time-series queries and formulas by __result desc; and log/trace scalar/time-series queries by the primary aggregation descending. Valid caller-supplied values are preserved. The response appends a decisions note when defaults are inserted.
• Guide routing: read signoz://logs/query-builder-guide for logs, signoz://traces/query-builder-guide for traces, signoz://metrics-aggregation-guide for metrics/formulas, and signoz://promql/instructions for PromQL.
• Time-series ranking caveat: top-N groups are ranked over the entire requested window. A short-lived spike can be omitted even when it dominates one bucket; narrow the window or adjust the limit when that matters.
• Backend warnings: non-fatal warnings the backend returns (e.g. ambiguous-key resolution) are surfaced as a note alongside the raw response and WARN-logged, matching the search/aggregate/query_metrics tools (previously the body was returned verbatim and warnings were dropped).
• Key-not-found errors: a filter referencing a key absent from the workspace's metadata for the queried signal fails with recovery guidance in the error text plus a machine-readable missingKeys array in the structured error content
