What I would do is monitor the queue using qmail-qstat or one of the other
utilities like it. Perhaps a good idea would be to check for a number of
messages you think is too high, and if the queue has the same or greater
messages within x timeframe then send the page.
Can you share some of the scripts you use for paging? We use one called
'checknet' that was written here...it does a cycle of pings across our
network, then it prioritizes which sytems, hubs, etc and pages with the ip
addresses of the non-responsive item. We are interested in moving to a
paging system that checks services, not just network 'upness'.
