5.1.2.3 Ensure journald is configured to compress large log files

Information

The journald system includes the capability of compressing overly large files to avoid filling up the system with logs or making the logs unmanageably large.

Uncompressed large files may unexpectedly fill a filesystem leading to resource unavailability. Compressing logs prior to write can prevent sudden, unexpected filesystem impacts.

Solution

Edit the /etc/systemd/journald.conf file and add the following line:

Compress=yes

Restart the service:

# systemctl restart systemd-journald.service
