We've just installed IPMonitor on the same box as Orion and would like to do a similar thing but I'm not much of a programmer and at the moment haven't got the time to experiment.
When I do and if I get it working I'll let you know.
I seem to recall in a different post that these two products will not merge, per se. Rather, the plan right now is to put the functionality of ipMonitor into Orion. I am like you, running both products. What I really want is to have a unified dashboard of alerts.
If I get anything working, I will post it.
