I can't say I've tried it myself, but I guess you could set them up so
they send passive checks to Nagios?

If they're unix/linux hosts you can use send_nsca and maybe the
nsca_wrapper script from nagios exchange which makes it easy to run
your checks from cron.

If they're WIntel hosts, you'll find send_nsca is built in to
NSClient++ or there's a standalone binary available on nagiosexchange
if you'd rather.

You could use freshness checking, so If Nagios doesn't receive a check
from one of your hosts for more than a few days it alerts you about
that as well.

hth, and please report back to say what you find works for you.

Cheers,

Jim
