Auditbeat and systemd
The DEB and RPM packages include a service unit for Linux systems with systemd. On these systems, you can manage Auditbeat by using the usual systemd commands.
The service unit is configured with UMask=0027 which means the most permissive mask allowed for files created by Auditbeat is 0640. All configured file permissions higher than 0640 will be ignored. Please edit the unit file manually in case you need to change that.
Use systemctl to start or stop Auditbeat:
sudo systemctl start auditbeat
sudo systemctl stop auditbeat
By default, the Auditbeat service starts automatically when the system boots. To enable or disable auto start use:
sudo systemctl enable auditbeat
sudo systemctl disable auditbeat
To get the service status, use systemctl:
systemctl status auditbeat
Logs are stored by default in journald. To view the Logs, use journalctl:
journalctl -u auditbeat.service
The systemd service unit file includes environment variables that you can override to change the default options.
| Variable | Description | Default value |
|---|---|---|
| BEAT_LOG_OPTS | Log options | |
| BEAT_CONFIG_OPTS | Flags for configuration file path | -c /etc/auditbeat/auditbeat.yml |
| BEAT_PATH_OPTS | Other paths | --path.home /usr/share/auditbeat --path.config /etc/auditbeat --path.data /var/lib/auditbeat --path.logs /var/log/auditbeat |
You can use BEAT_LOG_OPTS to set debug selectors for logging. However, to configure logging behavior, set the logging options described in Configure logging.
To override these variables, create a drop-in unit file in the /etc/systemd/system/auditbeat.service.d directory.
For example a file with the following content placed in /etc/systemd/system/auditbeat.service.d/debug.conf would override BEAT_LOG_OPTS to enable debug for Elasticsearch output.
[Service]
Environment="BEAT_LOG_OPTS=-d elasticsearch"
To apply your changes, reload the systemd configuration and restart the service:
systemctl daemon-reload
systemctl restart auditbeat
It is recommended that you use a configuration management tool to include drop-in unit files. If you need to add a drop-in manually, use systemctl edit auditbeat.service.
