This role provides an easy way to configure the systemd-journald logging service.

Requirements

See below

Collection requirements

If you want to manage rpm-ostree systems with this role, you will need to install additional collections. Please run the following command line to install them:

ansible-galaxy collection install -vv -r meta/collection-requirements.yml

Role Variables

The role allows system administrator to configure basic systemd-journald settings, through the following set of variables which form the role's public API.

  • journald_persistent - boolean variable which governs where journald stores log file. When set to true the logs will be stored on disk in /var/log/journal/. Defaults to false, i.e. volatile journal storage.

NOTE: The following settings apply to both persistent and volatile modes unless otherwise indicated.

  • journald_max_disk_size - integer variable, in megabytes, that governs how much disk space can journal files occupy before some of them are deleted. No implicit value is configured by the role, hence default sizing calculation described in man 5 journald.conf applies.

  • journald_max_files - integer variable that governs how many journal files can be kept at maximum while respecting max disk size settings for journal. No implicit value is configured by default.

  • journald_max_file_size - integer variable, in megabytes, describes the maximum size of single journal file. No implicit configuration is set up by the role.

  • journald_per_user - boolean variable, allows to configure whether journald should keep log data separate for each user, e.g. allowing unprivileged users to read system log from their own user services. Defaults to true. Note that per user journal files are available only when journald_persistent: true.

  • journald_compression - boolean variable instructs journald to apply compression to journald data objects that are bigger than default 512 bytes. Defaults to true.

  • journald_sync_interval - integer variable, in minutes, configures the time span after which journald synchronizes the currently used journal file to disk. By default role doesn't alter currently used value. This setting is only applicable for journald_persistent: true. You will get a warning if set otherwise.

  • journald_forward_to_syslog - boolean variable, control whether log messages received by the journal daemon shall be forwarded to a traditional syslog daemon. Defaults to false.

  • journald_rate_limit_interval_sec - integer variable, in seconds, configures the time interval within which only journald_rate_limit_burst messages are handled. See man 5 journald.conf for more information.

  • journald_rate_limit_burst - integer variable, sets the upper limit of messages from a service which are handled within the time defined by journald_rate_limit_interval_sec. See man 5 journald.conf for more information.
