Puppet Class: cis_security_hardening::rules::journald_compress

Defined in:
manifests/rules/journald_compress.pp

Summary

Ensure journald is configured to compress large log files

Overview

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.

Note: The main configuration file /etc/systemd/journald.conf is read before any of the custom *.conf files. If there are custom configs present, they override the main configuration parameters.

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

Examples:

class { 'cis_security_hardening::rules::journald_compress':
    enforce => true,
}

Parameters:

  • enforce (Boolean) (defaults to: false) —

    Enforce the rule
