NSClient++ Help (#1) - NRPE Checks fail - UNKNOWN: No Handler when running as service [SOLVED] (#592) - Message List
Hi there,
I'm having trouble with executing NRPE checks with NSClient++.
root@NAGPROD03:/usr/local/nagios/libexec# ./check_nrpe -H MF06NODE01 -c check_oracleping UNKNOWN: No handler for that command root@NAGPROD03:/usr/local/nagios/libexec#
There's nothing in nsclient.log. When I run NSClient++ /test the checks work fine:
C:\Program Files\NagiosClient>net stop nsclientpp && "NSClient++.exe" /test The NSClient++ (Win32) service is stopping. The NSClient++ (Win32) service was stopped successfully.
Launching test mode - client mode

When running as a service NRPE still responds, but none of the other checks (like check_es_ok) work.
root@NAGPROD03:/usr/local/nagios/libexec# ./check_nrpe -H MF06NODE01 I (0.3.8.69 2010-05-19) seem to be doing fine...
Has anyone else seen this? Have tried upgrading NSClient++ to latest stable, and confirmed service is running as local system.
Many thanks Gareth

Uhmm...
Why would there be a "check_oracleping" command?

Hi Michael,
Oops sorry for not making that clear in the previous post. I have configured a custom NRPE check below:
[modules]
FileLogger.dll
CheckSystem.dll
CheckDisk.dll
NSClientListener.dll
NRPEListener.dll
SysTray.dll
CheckEventLog.dll
CheckHelpers.dll
[NRPE]
port=5666
allow_arguments=1
allowed_hosts=10.10.12.97
[NRPE Handlers]
check_oracleping=scripts\oracleping.bat $ARG1$
nrpe_ok=scripts\ok.bat
But get the error above. It works when running nsclient++ /test
Also nrpe_ok gives the same thing? I've probably stuffed something up somewhere :/
Thanks for your help Gareth

Humm, ok...
Looks like some configuration miss match.,
Are you maybe running two instances?
nsclient++ /svc will give you the path of the service check that it is the correct one you use.
Also enable (debug) logging so you can see if there is anything wrong when you run it as a service.

I wanted to chime in as I have been having a similar problem.
My goal is to execute scripts on a Windows computer using the check_nrpe command.
[root]# /usr/local/nagios/libexec/check_nrpe -H 10.14.6.4
I (0.3.8.76 2010-05-27) seem to be doing fine...
[root]# /usr/local/nagios/libexec/check_nrpe -H 10.14.6.4 -c check_es_ok
UNKNOWN: No handler for that command
I can communicate with the Daemon, which means it isn't a connection issue. Any attempt to run any check command through the command line on my remote server gives the same UNKNOWN: No handler for that command.
Here is the relevant (to my knowledge) part of NSC.ini:
[modules]
NRPEListener.dll
NSClientListener.dll
FileLogger.dll
CheckSystem.dll
CheckDisk.dll
CheckEventLog.dll
CheckHelpers.dll
script_dir="C:\Program Files\NSClient++\scripts\"
[Script Wrappings]
vbs=cscript.exe T:30 NoLogo scripts\lib\wrapper.vbs %SCRIPT% %ARGS%
ps1=cmd /c echo scripts\%SCRIPT% %ARGS%; exit($lastexitcode) | powershell.exe -command -
bat=scripts\%SCRIPT% %ARGS%
[External Scripts]
check_es_long=scripts\long.bat
check_es_ok=scripts\ok.bat
check_es_nok=scripts\nok.bat
check_vbs_sample=cscript.exe T:30 NoLogo scripts\check_vb.vbs
check_powershell_warn=cmd /c echo scripts\powershell.ps1 | powershell.exe -command -
[External Alias]
. . .
check_ok=CheckOK Everything is fine!
[NRPE Client Handlers]
check_other=-H 192.168.0.1 -p 5666 -c remote_command -a arguments
Do I need to add something to the NRPE Client Handlers section?
Here are the entries from Nagios:
# 'check_nt' command definition
define command{
command_name check_nt
command_line $USER1$/check_nt -H $HOSTADDRESS$ -p 12489 -s
nagiosadmin -v $ARG1$ $ARG2$
}
# 'check_nrpe' command definition
define command{
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
define service{
use generic-service
host_name PC4
service_description Test
check_command check_nrpe! -c check_es_ok
}
define service{
use generic-service
host_name PC4
service_description Test2
check_command check_nrpe!-c ok.bat
}
Sorry for the lengthy post. What could be causing this?

Sorry for pseudo-spamming your board, I figured out why my set-up wasn't working: I had specified the external script directory under [External Scripts] but NOT under [NRPE].
Once I added the external scripts directory under the [NRPE] tag my scripts were properly executed by the check_nrpe command.
Hopefully others can learn from my mistake.

humm...
[External Script] ;# SCRIPT DIRECTORY ; All files in this directory will become check commands. ; *WARNING* This is undoubtedly dangerous so use with care! ;script_dir=c:\my\script\dir
That should work (if it does not it is a bug). But it should not be under [External Scripts].
NRPE has the same functions as the CheckExternalScripts module but it is "deprecated".
