remote checks without local nagios clients?

[Tedman Eng]

You can create your own rather easily using perl or shell wrapper around ssh
(or check_by_ssh) and parsing output.  I currently have ssh-based checks
using output from "df -k" and "vmstat" executed w/o plugins on the remotes.
I think I might have originally used one of the contrib scripts as a
template.

Subject: [Nagios-users] remote checks without local nagios clients?


I am not allowed to install nagios software on the remote hosts (remote
ssh keys are okay).

I can connect via ssh.

We do not run SNMP on the remote hosts.

I can do something like this from the nagios server:

./check_by_ssh -H 192.168.1.10 -4 -2 -C /usr/bin/uptime

returns this:
 10:04am  up 35 day(s), 21:27,  1 user,  load average: 0.00, 0.00, 0.01

>From what I can tell, "check_by_ssh" is supposed to call a nagios plugin
installed on the remote host.

Do I need to create a perl plugin to either call "check_by_ssh" and
parse output or make the ssh connection directly and parse output?

Or even better, does anyone have sample scripts they already use?

I have looked at push_check by jjoseph, but that seems to push software
to the remote system.

Big Brother has this from www.deadcat.net

"bb-central-1.5c.tar.gz
A set of extension scripts that allows monitoring of Big Brother UNIX
clients, without the need of locally installed Big Brother clients. All
is needed is ssh or rsh to regularly poll a client host and obtain the
information desired. Supports load average, disk, swap, procs and msgs.
Allows for local extensions, as well. Sample included local entensions:
Mail Queue, Disk I/O, Memory, and CPU modes."

Does something similar exist for nagios?

Thanks

Craig
