The action model
Definition
An action model is a predefined command that can be used in the configuration of a user service, a piece of equipment or a unitary service.
This command will only be executed when the status changes from confirmed OK to CRITICAL.
Its implementation is related to the resolution of problems which include for example the restart of a service (Windows or Linux) or the execution of a linux command.
This model catalogue will be enriched according to the needs of our customers.
Predefined action commands
Action templates support the following commands:
| Applicable A | Description | Action command |
| User Service | Writing a variable in the external application PCvue | write_arcinfo_pcvue_variable |
| Hosts | Write to the syslog file of the Linux device associated with the action. | write_syslog_host |
| Run a Dos or Powershell command on any Windows device via winexe on winrm. | launch_command_windows_host | |
| Call a URL in GET or POST by passing product variables in the URL or content. | call_url_host | |
| Unitary Service | Execute a command via SSH on any port, on the device associated with the service | launch_command_linux_debian |
| Run a Dos or Powershell command on any Windows device via winexe on winrm. | launch_command_windows_service | |
| Restarting a service on Debian Linux OS, via SSH, and on the device associated with the service. | restart_service_linux_debian | |

Select the unit service to be configured. The configuration window opens. Position yourself on the Action and choose the action model.
Enter the service to be restarted and click on Click Apply.
Note The configuration is the same for a user service or a device.
