How to manage operating system services

In this document, you’ll find the steps on how to manage operating system services.

Manage operating system services

To start, stop, and restart operating system services, you should use the orbit service command.

mt4adm@vmdf-giskard:~$ sudo orbit service --help
Usage: orbit service <service> <command>

Send commands to the systemd manager

Arguments:
 <service> The service name
 <command> Systemd command: [start|stop|restart|status]

Flags:
 --help Show context-sensitive help.
 --force Force the command execution, never prompt
 --show

For example, let's view the status of the SNMP service.

mt4adm@vmdf-giskard:~$ sudo orbit service snmpd status

Restart a service

To restart a service, use the restart command. The same syntax as the example can be used for the start and stop commands, which will start and stop services respectively.

mt4adm@vmdf-giskard:~$ sudo orbit service snmpd restart
