Journalbeat and systemd
editJournalbeat and systemd
editThe DEB and RPM packages include a service unit for Linux systems with systemd. On these systems, you can manage Journalbeat by using the usual systemd commands.
Start and stop Journalbeat
editUse systemctl to start or stop Journalbeat:
systemctl start journalbeat
systemctl stop journalbeat
By default, the Journalbeat service starts automatically when the system boots. To enable or disable auto start use:
systemctl enable journalbeat
systemctl disable journalbeat
Journalbeat status and logs
editTo get the service status, use systemctl:
systemctl status journalbeat
Logs are stored by default in journald. To view the Logs, use journalctl:
journalctl -u journalbeat.service
Customize systemd unit for Journalbeat
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/journalbeat.service.d directory.
For example a file with the following content placed in
/etc/systemd/system/journalbeat.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 journalbeat
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 journalbeat.service.
