Monitor Log Rotation Cron Jobs

The Problem

If log rotation fails, log files grow unbounded until they fill the disk. This crashes databases, stops services, and can require emergency intervention.

The Solution

Add CronRabbit monitoring to your logrotate cron entry or custom log cleanup script.

Critical Infrastructure

Log rotation is invisible infrastructure — it only gets attention when it fails. By then, disk is at 100% and services are crashing.

Code Examples

Bash

# Crontab entry
0 0 * * * /usr/sbin/logrotate /etc/logrotate.conf && curl -fsS -m 10 --retry 5 --retry-all-errors https://ping.cronrabbit.com/logrotate-id
