Ran into a weird issue today with report generation during load testing. Using JMeter 5.6.2 to simulate 200 concurrent users fetching /api/v2/analytics/report/realtime. The system throws HTTP 429 Too Many Requests after just 50 concurrent calls. Is there a specific rate limit for real-time analytics endpoints? I need to adjust my test plan but cannot find documentation on the exact threshold for this endpoint.
As far as I remember, the real-time analytics endpoint has a strict per-tenant ceiling, not just a global one. Hitting 429s at 50 concurrent calls is standard behavior for this specific API path. The rate limit is enforced at the gateway level to protect the live data streams.
Cause:
The default throttle for /api/v2/analytics/report/realtime is significantly lower than batch endpoints. JMeter threads hitting the endpoint simultaneously trigger the hard cap immediately. The system rejects excess requests to prevent latency spikes in live reporting.
Solution:
Implement exponential backoff in your test script. Do not fire 200 threads at once. Pacing requests via JMeter is the only way to stay compliant. Use the Retry-After header in the 429 response to calculate the wait time before the next request. This approach mimics actual client behavior and avoids gateway bans. Check the response headers for X-RateLimit-Remaining to monitor your quota dynamically during the load test.
