# Investigate an APM issue

`GET /applications/{application-identifier}/apm/issues/{issue-identifier}`

Returns one APM issue with typed occurrence metrics and recent affected traces in the requested window. Slow issues use milliseconds; count-based anti-patterns use call counts.

## Query parameters

- `start` string, date-time, required
- `end` string, date-time, required
- `recentTraceCount` integer

## Response `200`
