Monitoring & Maintenance
Log File Management
Unmanaged logs fill disks, crash databases, and hide attack evidence in noise. Disciplined log management, rotation, remote copies, retention policy, and periodic review, keeps servers healthy and incidents investigable.
Key points
- Rotate and compress all service logs with size and age caps.
- Ship security-relevant logs to remote storage immune to local tampering.
- Set retention by purpose: 90+ days security, 30 days operational typical.
- Alert on error-rate spikes and authentication anomalies automatically.
- Review logs proactively weekly, not only after incidents.
- Exclude or sample health-check noise that drowns real signals.
- Protect log contents, they contain credentials, PII, and attack data.
- Include log review in every post-incident and audit cycle.
Field note
Set up rotation before you need it, because you discover missing rotation at 2 a.m. when the disk hits 100% and the database stops. Every time.
Frequently asked questions
Why did the disk fill overnight?
Almost always logs, debug modes left on, runaway errors, or missing rotation. Fixable permanently in one pass.
How long should logs be kept?
Security: 90 days minimum for forensics. Operations: 30 days. Compliance may demand more.
Do attackers delete logs?
Routinely, which is why remote, append-only copies are non-negotiable.
Can log analysis find hacks?
Often the first sign: odd user agents, off-hour admin hits, and outbound anomalies all show in logs.
