Metricbeat and systemd

edit

The DEB and RPM packages include a service unit for Linux systems with systemd. On these systems, you can manage Metricbeat by using the usual systemd commands.

Start and stop Metricbeat

edit

Use systemctl to start or stop Metricbeat:

systemctl start metricbeat
systemctl stop metricbeat

By default, the Metricbeat service starts automatically when the system boots. To enable or disable auto start use:

systemctl enable metricbeat
systemctl disable metricbeat

Metricbeat status and logs

edit

To get the service status, use systemctl:

systemctl status metricbeat

Logs are stored by default in journald. To view the Logs, use journalctl:

journalctl -u metricbeat.service

Customize systemd unit for Metricbeat

edit

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/metricbeat/metricbeat.yml

BEAT_PATH_OPTS

Other paths

-path.home /usr/share/metricbeat -path.config /etc/metricbeat -path.data /var/lib/metricbeat -path.logs /var/log/metricbeat

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/metricbeat.service.d directory.

For example a file with the following content placed in /etc/systemd/system/metricbeat.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 metricbeat

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 metricbeat.service.
