Heartbeat and systemdedit

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.

The service unit is configured with UMask=0027 which means the most permissive mask allowed for files created by Heartbeat 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.

Start and stop Heartbeatedit

Use systemctl to start or stop Heartbeat:

sudo systemctl start heartbeat-elastic
sudo systemctl stop heartbeat-elastic

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

sudo systemctl enable heartbeat-elastic
sudo systemctl disable heartbeat-elastic

Heartbeat status and logsedit

To get the service status, use systemctl:

systemctl status heartbeat-elastic

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

journalctl -u heartbeat-elastic.service

Customize systemd unit for Heartbeatedit

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/heartbeat/heartbeat.yml

BEAT_PATH_OPTS

Other paths

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

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/heartbeat-elastic.service.d directory.

For example a file with the following content placed in /etc/systemd/system/heartbeat-elastic.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 heartbeat-elastic

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-elastic.service.
