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

Customize systemd unit for Heartbeatedit
The systemd service unit file includes environment variables that you can override to change the default options.
Flags for configuration file path
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=-e -d elasticsearch"

To apply your changes, reload the systemd configuration and restart the service:
systemctl daemon-reload systemctl restart heartbeat
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 heartbeat.service.
