APM Server and systemd
editAPM Server and systemd
editThe DEB and RPM packages include a service unit for Linux systems with systemd. On these systems, you can manage APM Server by using the usual systemd commands.
Start and stop APM Server
editUse systemctl to start or stop APM Server:
systemctl start apm-server
systemctl stop apm-server
By default, the APM Server service starts automatically when the system boots. To enable or disable auto start use:
systemctl enable apm-server
systemctl disable apm-server
APM Server status and logs
editTo get the service status, use systemctl:
systemctl status apm-server
Logs are stored by default in journald. To view the Logs, use journalctl:
journalctl -u apm-server.service
The unit file included in the packages sets the -e flag by default.
This flag makes APM Server log to stderr and disables other log outputs.
Systemd stores all output sent to stderr in journald.
Customize systemd unit for APM Server
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 |
|
To override these variables, create a drop-in unit file in the
/etc/systemd/system/apm-server.service.d directory.
For example a file with the following content placed in
/etc/systemd/system/apm-server.service.d/debug.conf
would override BEAT_LOG_OPTS to enable debug for Elasticsearch output.
[Service] Environment="BEAT_LOG_OPTS=-e -d elasticsearch"
To use settings from the APM Server file, empty the environment variable. For example:
[Service] Environment="BEAT_LOG_OPTS="
To apply your changes, reload the systemd configuration and restart the service:
systemctl daemon-reload systemctl restart apm-server
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 apm-server.service.
