What I do is the following:

- If a critical node (I haven't got it working for interfaces, although it
seems there's some discrepancy between interfaces, segments and networks
that I have to investigate) goes down and no up trap is received after x
minutes, I put that node in a perl database.
- Each node in the perl database is pinged every 10 minutes to see if
they've come up, and an email is sent out with its status (usually it's down
because of the next step)
- If a node up trap is received, the node is checked against the database,
if it is in the database (ie. a critical node that had been down), then it
is removed from the db, and a confirmation email is sent...

Cheers

Matt
