Sorry if this is a silly or basic question.

We're still using the old KNM Distributed Edition v4.1 on a separate server.  I'd like to get rid of it because  I was led to believe we could use the VSA Network Monitor module to do the same. But this module seems to be way overkill for what I'm trying to do.

In the standalone module all we do are PING checks on the Public IP address of ISP modems for our clients.  A failed PING sends an email.  That's it.  Super simple.  Nothing complex. There are no agents involved.

I've tried to replicate this in the Network Monitor module but it seems bizarre on how to configure. I seemed to be forced to tie these PING checks to an agent.  Maybe I'm off course or too dense to figure this out.  Support sent me an 80 page PDF that is 4 years old.  

I would greatly appreciate a push in the right direction.
