[Xymon] Question on controlling alerts.

If I have multiple files being checked or multiple services being checked how do I control alerts for a specific item.? Such as two processes:? Process1 and Process2.? One of them goes red.? How do I send an alert based on the correct item.? Is it indexed or something.? I have looked in forums and email history for last several years but have not found how to do this?

Thanks Paul Jordan
