checking unix load/disk space

[Jeff Scott]

You should also specify "-e ssh", and make sure blade1 resolves.

I am using trusted SSH connection but getting the following error while
running the script. Is there a pre-requisite for these scripts?


[root at NGMON downloads]# ./check_disk_remote -H blade1 -w 20 -c 25 -v

I have uploaded a few "network" aware scripts to nagiosexchange.org to
do
just this.  They check disk, load, etc...via ssh, with trusted keys
setup,
or with rsh (if .rhost/host.equiv are setup).  Obviously ssh is
preferred
method.

Only if the plugin is network aware and understands -h parameters ;) In
this case, it won't work as check_disk is a local check only and not
network aware.

Yes, you do. The host-resource plugins are not network aware. You can
always see if a plugin is network aware by running it with '--help'. In
this case, check_disk must be run on the host you intend to check. There
are a number of ways to do that but the most common are NRPE or
check-by-ssh.
