Tools (13)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • get_intelligence_snapshotLatest detected anomalies

    Return the latest precomputed health score, anomalies, insights, and recurring warning or error log patterns.

  • get_observability_overviewSystem health overview

    Summarize service health for a bounded telemetry window. Start here for incident triage.

  • get_service_dependenciesService dependency traversal

    Find upstream or downstream dependencies of one service with minimum hop counts. Uses the full scoped edge rollup, handles cycles, and reports truncation from depth or node limits.

  • get_service_performanceService performance explorer

    Display separate latency, error rate and request rate panels plus a Slow operations table showing p95 duration grouped by operation over server and consumer spans, covering HTTP, gRPC and message consumers, for one service or the system.

  • get_service_topologyService dependency topology

    Return services and observed dependency edges with health, traffic, latency, and error data.

  • get_telemetry_schemaTelemetry schema

    List the signals, columns with their common values, attribute keys seen per service, metric names, services, measure functions, units and SQL-only relations in sql_relations. Read this before drafting panels so filters use values that exist. Compare time columns with TIMESTAMP 'YYYY-MM-DD HH:MM:SS' (UTC), or cast TIMESTAMPTZ literals with ::TIMESTAMPTZ_NS. See create_dashboard for the spec guide.

  • inspect_traceTrace detail

    Inspect an exact trace, or select the most relevant recent error or slow trace, with spans, waterfall, flame graph, and correlated logs.

  • list_panel_exemplarsPanel exemplars

    Find bounded traces for a panel selection.

  • preview_panelsPreview panels

    Check and run panels without saving them. Each panel reports ok with rows and a sample, empty with the reason, error, or invalid with the exact field and a suggestion. The result includes total elapsed_ms and executed per-panel elapsed_ms; invalid and not_run panels omit elapsed_ms because they were not executed. Fix every invalid panel and replace or drop every empty one before saving. Spec guide: see create_dashboard.

  • query_panel_fragmentRefresh telemetry panels

    Run every panel in a dashboard fragment; panel subsets are forbidden.

  • query_telemetryTelemetry panel

    Display one v1 panel in chat as an executable dashboard fragment. Use get_telemetry_schema to discover fields; see create_dashboard for the spec guide. The authored spec plus vars must fit 128 KiB (131072 serialized JSON bytes); larger inputs are rejected with their actual size.

  • resolve_panel_variablesPanel variable options

    Resolve variable options within a dashboard fragment window.

  • search_logsLog explorer

    Search and filter logs with a severity timeline and links back to correlated traces.
