Newbie needs help...."unknown" status?

Hi, Nagios Newbie here.....I am setting up Nagios to monitor multiple servers on my network. (Win 2003 server machines). I am running Nagios 3.2.1 on Ubuntu linux.
Three of my services being monitored work perfectly:
Memory Usage
NSClient++ Version
Uptime
The other four only ever return a status of "Unknown":
C: Drive Space
CPU Load
Explorer
W3SVC
I have checked the configuration files for the windows.cfg and from all I can tell, it looks OK, as does the nagios.cfg and the command.cfg.
Here is a sample of my service definitions for the checks *not* working:
Code: Select all
define service{
use generic-service
host_name myserver
service_description CPU Load
check_command check_nt!CPULOAD!-1 5,80,90
}
define service{
use generic-service
host_name myserver
service_description C:\ Drive Space
check_command check_nt!USEDDISKSPACE!-l c -w 80 -c 90
}
define service{
use generic-service
host_name myserver
service_description W3SVC
check_command check_nt!SERVICESTATE!-d SHOWALL -1 W3SVC
}
define service{
use generic-service
host_name myserver
service_description Explorer
check_command check_nt!PROCSTATE!-d SHOWALL -l Explorer.exe
}
Any pointers are greatly appreciated!!

I would check the configuration file on the NSClient, not all of the checks are enabled on the client by default, so you'll have to turn them on for it to send the data.
If that doesn't fix it, can you send the full "status information" message for each of these services. The error messages "should" point to where the problem is.

You also probably need to enable the "allow_arguments" (or something like that) setting in the NSClient++ config.

All of the modules in the nsc.ini are enabled with the exception of CheckWMI.dll:
Code: Select all
[modules]
NRPEListener.dll
NSClientListener.dll
FileLogger.dll
CheckSystem.dll
CheckDisk.dll
CheckEventLog.dll
CheckHelpers.dll
;# NSCLIENT++ MODULES
;# A list with DLLs to load at startup.
; You will need to enable some of these for NSClient++ to work.

CheckTaskSched.dll
I enabled the allow-arguments (set it to = 1 ?) and re-ran the check on that particular server with the same results.
Here are the status information messages showing in the web interface for these services:

I appreciate the help!!
Let me know if there is any other info that could be helpful in tracking this problem down.

I guess the next step would be to check your arguments in the actual commandline to see what the output is.
Code: Select all
cd /usr/local/nagios/libexec
./check_nt (your commandline arguments)
I'd try messing with that until you get something returned for a status. There may be an invalid or missing argument or something in the command definition and that's the best way to check it.
