API health by endpoint
Find the endpoints with the highest error rate and latency against your targets.
Reliability & managed IT servicesHow it's worked out
- Error rate = 5xx ÷ requests per endpoint. Breach = error rate or p95 above target
- Same period for every endpoint; client errors (4xx) excluded
NoteRank by user impact: a busy endpoint with a moderate error rate can hurt more than a rare one with a high rate.
