THE Linux services monitor tracks the status of Linux services by observing application availability and detection of failures. The status uses one of the following return codes:

  • 0: Running
  • 1: Stopped

The agent raises an alert if the original status does not match the return code.

To manage Linux services, a Linux services monitor can be added using Setup > Monitoring > Templates > Other Monitors. For more information, see Validate Template.

After applying the template to a device, the template can be validated if it is assigned to a resource.
