Stuck on 429 Too Many Requests errors when pushing 200 concurrent WebSocket connections to the analytics metrics endpoints. The rate limit header resets too slowly for our load test ramp-up.
Tried increasing JMeter thread group ramp-up time from 10s to 60s.
Verified API key permissions include full analytics scope.
The documentation actually says WebSocket streaming is not intended for high-throughput load testing; use the batch metrics API instead. Switching to an analytics query allows you to aggregate data in chunks, bypassing the per-tenant WebSocket throttle entirely.
