I've been using Nagios for 5+ years and as such, have a massive config
from the old 1.x version. I use NSClient+ on the Windows side.
All of my commands for disk space require defining Critical and
Warning levels.
i.e.
define command{
command_name check_nt_disk_d
command_line /usr/local/nagios/libexec/check_nt -H
$HOSTADDRESS$ -p 1248 -v USEDDISKSPACE -l d -w 95% -c 98%
}

Hi all, looking for my Nagios gurus out there.
I'm trying to monitor some Windows systems using Nagios through
OSSIM. OSSIM is just an SIEM platform that rolls a bunch of open
source security stuff like snort, nagios, ntop, openvas, etc. into
one nice package with a great web interface. It ships with Nagios3,
and it sort of has its own idea of where/how nagios configs should
be placed.
Regardless, I am trying to use the "check_nt" command to poll
various information on my Windows servers. So far, a lot of the
checks are working properly, but some are not and I can't figure out
why. The cfg file for the server has the following service check for
disk usage:
# Create a service for monitoring D:\ disk usage
# Change the host_name to match the name of the host you defined above
define service{
use generic-service
host_name SERVERNAME
service_description D:\ Drive Space
check_command check_nt!USEDDISKSPACE!-l d
}
Within the actual OSSIM web site where you can see statistics/info
on your monitored systems, it shows an "OKAY" for many of the
checks, but for this USEDDISKSPACE check, it says: missing -l
parameters
That references check_nt, I am fairly certain means "nt.cfg" which
is located at /etc/nagios-plugins/config and has the following
content:
# 'check_nt' command definition
define command {
command_name check_nt
command_line /usr/lib/nagios/plugins/check_nt -H
'$HOSTADDRESS$' -p 12489 -v '$ARG1$' '$ARG2$' '$ARG3$'
}
I hardcoded the port into that command as none of the checks were
working at all without it. Now the checks for memory, CPU, etc. work
- but this one still doesn't. Moving on.
The file located at /usr/lib/nagios/plugins/check_nt seems to be a
binary file of some sort. I am assuming that because catting it just
spits out a bunch of garbage.
The "-l d" argument above tells it to check the disk space on drive
letter D. I know that check_nt is working properly because if I
manually run it from the command line, it's successful:
hostname:/etc/nagios-plugins/config# /usr/lib/nagios/plugins/
check_nt -H 10.0.10.10 -p 12489 -v USEDDISKSPACE -l d
d:\ - total: 2.00 Gb - used: 0.01 Gb (1%) - free 1.99 Gb (99%) | 'd:
\ Used Space'=0.01Gb;0.00;0.00;0.00;2.00
So, that works. Where is the disconnect between what I'm doing on
the command line and what's in the config script? I'm at a loss. Any
feedback or assistance is greatly appreciated.
Thanks all!
