The DEB and RPM packages include a service unit for Linux systems with systemd. On these systems, you can manage Filebeat 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 Filebeat 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.
systemctl to start or stop Filebeat:
sudo systemctl start filebeat
sudo systemctl stop filebeat
By default, the Filebeat service starts automatically when the system boots. To enable or disable auto start use:
sudo systemctl enable filebeat
sudo systemctl disable filebeat
To get the service status, use
systemctl status filebeat
Logs are stored by default in journald. To view the Logs, use
journalctl -u filebeat.service

The systemd service unit file includes environment variables that you can override to change the default options.
Flags for configuration file path
You can use
BEAT_LOG_OPTS to set debug selectors for logging. However,
to configure logging behavior, set the logging options described in
To override these variables, create a drop-in unit file in the
For example a file with the following content placed in
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 filebeat
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 filebeat.service.
