I read one person suggest having one server monitor them all, which in general is good, BUT, you still need to have something monitor the monitor server, at least a little bit.

I mean if you regularly get notified of things and then all of a sudden don't, you might not notice it for a while, even if the secondary monitoring is just are the services running and responding should be probably good enough..

I keep reading this in the posts..
