I would like to gather some advice form the more experienced Opmanager users on this forum, We currently have Whats Up Gold 16. I am looking at moving it over to OpManager for several reasons. 

My problem i have is that we have Custom Active Monitors on Whats Up configured to Telnet to a server and execute a script on that server to determine if the service is up or down. Now its not a complicted script it merely contains the following: Send=Monitor, Expect=ACK, That's it. I have managed to setup a Custom Monitor in OPManager but i dont know how to get the monitor to execute the script with the content mentioned above 

Does anyybody know how to configure Op Manager to perform the same

Any advice will be greatly appreciated

Thanks in Advance
