Please consider reposting on-list. I would like to see some discussion on
this thread.

I'm curious about the inhouse paging. We've been looking for something like
that. And I am looking at writing a job that wakes up, runs tests,
calculates the pause until the next boundary, and pauses for that.

We still have lots of "I ran" messages, apparently the default in Ecometry.
It's gotten so that those are ignored. The operator has asked me to cut down
on those. What I've been working to improve is monitoring events that
require response. As I posted, I had once worked on a system with the kind
of redundant monitoring I described. Pretty hard to lose both, if the system
is up. And, we have What's Up Gold for those sorts of problems.
