Anyone know to inform the pq applications are dowm or unknow server is up??
See image.
For the AD fail... drill into the component list for that application and look at which component(s) are listed as failing.
For the Linux Script component, it looks like a bug in the script. Does the script require user interaction? Does it require permissions that don't exist when run by the monitor?
For the Apache error... is the Apache Web Server configured on the port defined in the monitor? It seems to be not finding an instance of Apache on your server, suggesting a port misconfiguration at the most likely cause.
The Apache template requires that the Server-Status module, AKA mod_status is enabled and configured on the Apache web server to function properly. You will also need adequate permissions for the script to run properly. Ensure you're using a root level account.
The Active Directory failures are likely the result of user accounts being locked out and disabled, but without more screenshots or an error message it's difficult to say for certain.
