New Relic APM Investigation

Use New Relic MCP data to investigate application errors, latency, throughput, and transaction behavior. Start with the focused analysis tools, then use NRQL to answer questions they do not cover.

Investigation

1. Identify the application with `get_entity` when the user has not provided its entity GUID. 2. Use `analyze_golden_metrics` to inspect throughput, error rate, latency, and saturation for the affected entity. 3. Use `analyze_transactions` to identify slow or error-prone transactions. 4. Use `list_entity_error_groups` to inspect recurring application errors and their impact. 5. Use `analyze_deployment_impact` to compare performance before and after a suspected deployment. 6. Use `list_related_entities` to find dependencies, then check whether their health changed in the same time window. 7. Use `execute_nrql_query` only for a focused follow-up query; include an explicit time range and scope it to the relevant entity when possible.

Treat correlation as evidence, not proof of causation. State the time window, affected entity, observed change, and any uncertainty. Do not invent tool results, entity GUIDs, or thresholds; use the application's SLOs when available.

Example NRQL follow-up:

SELECT percentage(count(*), WHERE error IS true) AS 'Error rate',
       percentile(duration, 95) AS 'p95 duration'
FROM Transaction
WHERE entity.guid = '<ENTITY_GUID>'
