How to detect:
Monitor gen_ai_client_operation_time for sudden spikes or failures. Track HTTP 429 errors in langchain_chain_error logs. Correlate rate limit errors with request volume increases and failed token spend.
Recommended action:
Implement exponential backoff retry logic for rate limit errors. Add request queuing with rate limit awareness. Monitor provider-specific rate limit headers and proactively throttle requests. Alert when retry attempts exceed thresholds indicating sustained rate limiting.
