Metricbeat and systemd
editMetricbeat and systemd
editThe 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
editUse 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
editTo 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
editThe 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 |
|
BEAT_PATH_OPTS |
Other paths |
|
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.
