This Knowledgebase article provides information about how to disable the Neverfail Monitor service for an Anti-Virus (or a third-party) application on a server pair protected by a Neverfail AM(X).
Situations may arise where an unprotected third party application that runs on your Neverfail server, may impact server performance and overall server activity. Potentially, it may lock or keep files from the protected set open, which can cause the pair to be 'out-of-sync'. Therefore, it may be necessary to disable Neverfail Monitor service for Anti-Virus or third party applications to isolate or diagnose an issue.
Neverfail Monitor Service
The Neverfail Application Module Monitor Service automatically polls the component services of the protected applications identified at install time. This regular check on the state of each component service ensures the services are running correctly. If a component service is found to have failed, remedial actions can be taken - up to three consecutive failures for each service. The remedial actions on component service failure range from simply raising events in the Windows Application Event log to performing a switchover.
By default, these actions are set to 'Restart' and can be changed using the Configure Monitoring window. The desired action can be set for each successive time the service is found to have failed.
When a third party application protected by Neverfail is disabled (not uninstalled), its services are stopped so the Neverfail Application Module Monitor will consider that the services have failed and will restart them again. To avoid this, before disabling the application, you should configure the remedial actions to be taken by the Application Module Monitor when it finds a stopped protected service to be set to 'No Action' for each failure.
To disable Neverfail Monitor Service for an application, follow these steps:
- Open the Configure Monitoring window on the active server (by going to Start -> Programs -> Neverfail -> Configure Monitoring .
- When prompted, choose the Application Module that protects the services you will disable.
- From the services listed under 'Services' tab, select the specific service you want to disable. For each of the three actions to be taken at failure, choose 'No Action' from the drop-down list.
- Click the Apply button to save the settings and File -> Exit to close the window.
The third party application can now be disabled (disable the service or a stop the service) and the Application Monitor will not restart it. When re-enabling the application, make sure that the remedial actions are set back to 'Restart' (or any suitable action such as changing its service status back to manual).
