lb/Analyze Timeout Health Check Log

Analyzes logs with the detailed health check state TIMEOUT

Product: Load balancing
Step Type: AUTOMATED STEP

Description

None

Uncertain Reason

In the health check logs, we found logs with the detailed health state TIMEOUT. The backend might be timing out because:

  1. The application is overloaded and taking too long to respond.
  2. The backend service or health check timeout is too low.
  3. Connection to the endpoint cannot be established - the backend instance has crashed or is otherwise unresponsive. The following responses were received from your backends: {probe_results_text_str}

Uncertain Remediation

  1. Make sure that the backend service timeout (current value: {bs_timeout_sec}s) and health check timeout (current value: {hc_timeout_sec}s) are appropriately configured to accommodate your application’s expected response time.
  2. Investigate your application’s configuration to ensure it is correctly handling health check probe requests. {success_criteria}
  3. Check if firewall rules or iptables configurations are not blocking the health check probes from reaching the backend instances, resulting in timeouts.
