KnovvuCAErrorLogs

Meaning

This alert is triggered when the number of error-level logs generated by a service within Knovvu Analytics exceeds a high threshold over a short period. It indicates that a component is likely experiencing a failure or repeated operational issue. The alert is marked as critical if the number of error logs exceeds 250 in a 5-minute window.

Impact

If a service is generating excessive error logs:

• It may be experiencing runtime issues such as unhandled exceptions, resource exhaustion, or misconfigured inputs.
• Upstream or downstream processing could be affected due to cascading failures.
• User-facing features may become unreliable or unresponsive.
• The logs may fill storage rapidly, potentially impacting observability or system performance.

Diagnosis

• Identify the affected service from the alert label.
• Inspect the logs for the specific service and look for repeating stack traces, exceptions, or error messages.
• Correlate the error spike with recent activity (e.g., deployment, configuration change, traffic surge).
• Use service-level dashboards to check health metrics such as CPU, memory, thread pool exhaustion, or request latency.
• Review dependency health if errors indicate failure in communication with external services (e.g., database, message queue, downstream APIs).

Mitigation

• Roll back recent changes if the issue coincides with a deployment or configuration update.
• Restart the affected service if it appears to be in a faulted or degraded state.
• Apply hotfixes or patch known bugs causing recurring errors.
• Tune error handling to reduce the impact of recoverable issues and prevent cascading failures.
• If the error volume is expected (e.g., due to invalid input spike), document and silence the alert temporarily with clear justification.
• Escalate to engineering if the root cause cannot be resolved quickly or if user impact is significant.
