List business applications visible to the configured API Client. Optionally filter to apps that have been "alive" in the last N minutes (SaaS only).

Fetch business transactions, tiers, nodes, and backends for one application in parallel. Anchor for nearly all RCA workflows.

Walk the metric hierarchy for one application. Without metricPath returns top-level folders; with metricPath returns the children at that level. Cached for 5 minutes.

Fetch one or more metric paths over a time range using metric-data-v2. Defaults to BEFORE_NOW 30 minutes with rollup=true. Surfaces granularity and long-window warnings.

Retrieve slow/error/diagnostic transaction snapshots for an application. Default cap 100, hard max 600. Use needExitCalls=true to feed dependency-map analysis.

Retrieve open / recently-closed health rule violations for an application within a time window.

Retrieve anomaly violations for an application within a time window. Set fetchSuspectedCause=true to include the suspected-cause RCA payload (eventDetailMap.{id}.suspectedCauses[]).

Retrieve up to 600 events for an application by type and severity within a time window.

List health rule summaries (id, name, enabled) for an application via the Alerting REST v1 API. Optionally fan out to fetch full rule definitions.

Composite read: parallel-fetches health rules + policies + actions + schedules for one application via the Alerting REST v1 API. Use this for "what alerts and to whom" inventories.

Run an ADQL query against the Events Service. Mode A: single ADQL string. Mode B: array of ≤20 query objects. Requires APPD_EVENTS_SERVICE_URL and APPD_EVENTS_API_KEY to be configured.

Synthesize a tier→tier/backend dependency map from the application model + transaction snapshots (with exit calls). MCP-level aggregation — confidence depends on snapshot density (warning surfaces when sparse).
