Log Management Without the Complexity: A Practical Guide for Growing Teams
Every production incident eventually ends with someone searching logs. The difference between a 5-minute resolution and a 3-hour one often comes down to whether logs are structured, searchable, and retained long enough to matter.
Logs are the most verbose source of truth in your system. They are also the most expensive to store and search. Here is how to get maximum value from logs without drowning in them.
Structured logging: the foundation
Unstructured logs are text you search with grep. Structured logs are JSON you query like a database.
import logging, json
logging.info(json.dumps({
'event': 'payment_processed',
'user_id': user.id,
'amount': amount,
'duration_ms': elapsed,
'trace_id': current_trace_id()
}))
Every log line should include: timestamp, log level, service name, trace ID, and the specific event. Nothing else is required.
Log levels as a triage tool
- ERROR — something failed, action required - WARN — unexpected but recoverable, investigate soon - INFO — normal operational events - DEBUG — verbose, only in development
Production should log at INFO level. Alert on ERROR rate; review WARN trends weekly. Never enable DEBUG in production — it will fill your storage and contain sensitive data.
Retention strategy by log type
- Application errors: 30 days searchable, 1 year cold archive - Access logs: 7 days searchable, 90 days cold archive - Audit logs (auth, billing): 1 year searchable, 7 years cold archive (compliance) - Debug logs: do not store
Cold archive (S3 Glacier equivalent) costs <$0.004/GB/month — keep compliance logs forever there.
Connecting logs to AlertsDock monitors
When an AlertsDock monitor fires, your first action is to search logs for the period of the incident.
Include your AlertsDock monitor name or ID in logs generated during requests that are monitored, so you can immediately filter to the relevant log stream when an incident fires.
Log-based alerting
Complement uptime monitors with log-based alerts: - Alert when ERROR rate in logs exceeds 1%/minute - Alert when a specific error message appears (e.g. 'database connection refused') - Alert when log volume drops to zero (your app stopped logging = crashed)
