SNMP is a universal 'agent'. I dont know of any other specifically
written agents, but Argus will easily accommodate anything you can throw
so long as the Big brother or nagios agent talks over IP, Argus can
communicate with it. I cant think of a time I'd rather have a daemon
besides SNMP on the remote machines, though.

Argus doesnt receive any events. It proactively polls things. One
could easily write a daemon to listen for traps, and have argus monitor
that daemon, though.
When you receive a trap, you are depending on everything working
correctly, which [for anything besides informational purposes] is silly.
When you proactively poll a service, you're sure.

yep. docs on "cron" are included.

no flapping recognition that i know of. I'm not sure how that could be
implemented correctly (I can obviously think of a few ways to implement
In addition to your other prerequisites, you can ack via AIM. acking
via AIM and email doesnt come out-of-the-box, but it's trivial to
implement. note unless you set up PGP, ACKing via email or AIM is

not paging between certain hours is easy. See "cron" in the docs.
Queuing pages is not supported without your own code.
This can be overcome by creating a 'Log' method that will log all the
status changes to a text file, or to sql database or [...], and looking
at the log in the morning.

each notification has it's own unique* id.

yep. see 'Method' in the docs.

We've requested a 'warning', but Argus' author is taking an "I dont know
how to do it because I'm not that good" approach.

it's clear you havent even tried Argus :) Argus is a good thing.
Argus plays well with external utilities. Provided, is an 'argusctl'
program, which lets external utilities play with Argus.
