Example use cases
Debugging a server error log
“Can you parse this log line and tell me what went wrong: '2024-01-20T09:15:33Z CRITICAL [db-pool] Max connections exceeded: 500/500 active, request queued for 30s'?”
Extracting fields from nginx access logs
“I have this nginx access log line — parse it into structured fields like IP, timestamp, method, path, status code, and response size: '192.168.1.1 - - [20/Jan/2024:10:00:01 +0000] "GET /api/health HTTP/1.1" 200 1234'”
Triaging an application alert
“Here's a log line from our app — extract the severity and error message so I can decide if it needs immediate attention: 'Jan 20 10:45:00 app-server myapp[1234]: WARN: Retry attempt 3 of 5 for payment processor webhook delivery'”
