NRPE vs. check_by_ssh vs. nagios_statd

[Steven Grimm]

If you want to check multiple services on remote hosts using ssh, you
might want to look at my batch_by_ssh script, which will check all of
a remote host's services with one ssh command (rather than one ssh
per remote service) which should reduce your scaling woes.  It's still
not as cheap as NRPE, but especially if you have several services per
host on a ton of remote hosts, it'll cut way down on ssh overhead.
It also lets you centrally manage the commands that are run on remote
hosts, rather than doing it on config files on those hosts as with NRPE;
whether that's a plus or a drawback is a matter of taste.

There's extensive documentation (by Nagios plugin standards, anyway)
at the top of the script.

If you use it you'll want to make sure you've applied the following
check_by_ssh buffer overflow patch:
