Data Engine runtime

Service management

Data Engine runs as a service and the management is different depending on the system it runs on.

CClinux 4

The runtime starts as a service and can be controlled by systemctl. Use either enable or disable to control if Data Engine should autostart or not:

sudo systemctl enable dataengine
sudo systemctl disable dataengine

The service may also be started or stopped while the system is running:

sudo systemctl start dataengine
sudo systemctl stop dataengine

Output from the service can be checked with journalctl:

sudo journalctl -fu dataengine
