Overview
Domain expertise for diagnosing application failures through CloudWatch log analysis. Discovers relevant log groups, searches for error patterns and stack traces, performs root cause analysis, and generates prioritized remediation recommendations.
Troubleshoot a failing application
To diagnose and resolve application failures using CloudWatch logs, follow the procedure exactly. See Application failure troubleshooting procedure.
Troubleshooting
No log groups found
Ask the user for specific log group names. Common patterns: /aws/lambda/function-name,
/aws/apigateway/api-name, or custom application log groups.
Access denied errors
Verify AWS credentials have logs:DescribeLogGroups, logs:DescribeLogStreams,
logs:StartQuery, and logs:GetQueryResults permissions.
Query timeouts
Reduce the time window or limit results. Large log groups may require multiple smaller queries.
