Configuring logrotate for hourly rotation

You can configure logrotate to handle log rotation on an hourly basis to manage storage issues caused by excessive log files.

Below are the step-by-step instructions for modifying the logrotate configuration.

  1. Open the rsyslog logrotate configuration file in a text editor.

    sudo vim /etc/logrotate.d/rsyslog
  2. Modify the configuration to set up hourly rotation.

    1. Change the rotate directive to 6. rotate 6

    2. Change the weekly directive to hourly. hourly

    3. Add the maxsize directive if it is not already present. maxsize 0

  3. Test the configuration to ensure there are no syntax errors.

    sudo logrotate -d /etc/logrotate.conf
  4. Open the logrotate timer configuration file in a text editor.

    sudo nano /lib/systemd/system/logrotate.timer
  5. Modify the timer to trigger log rotation hourly. Change OnCalendar=daily to OnCalendar=hourly

  6. Restart the logrotate.timer to apply the changes.

    sudo systemctl daemon-reload
    sudo systemctl restart logrotate.timer
  7. If needed, clear other log files using the following commands to free up more storage.

    sudo rm -f /var/log/*.gz /var/log/*.1 /var/log/*.old
