Windows NRPE argument error

[inas.labib]

Hi ,

We enabled nrpe @ windows server and trying to execute the command from nagios. but we receive error as below.
Attached the ncs.ini configuration file for reference.
Please advice

Nagios command line :
nagios@nagios_server:/usr/local/nagios/libexec$ ./check_nrpe -H <clientip> -p 5666 -t 60 -c check_Visa_Session_Count_Pos -a '"arg1" "arg2" "arg3"'
Could not construct return packet in NRPE handler check client side (nsclient.log) logs...

@Windows server:

Entry @ NCS.ini
[NRPE Handlers]
command [check_Visa_Session_Count_Neg]=cmd /c echo scripts/netsta_review_Neg $ARG1$; $ARG2$; $ARG3$; exit $LastExitCode | powershell.exe /noprofile -command -
command [check_Visa_Session_Count_Pos]=cmd /c echo scripts/netsta_review_Pos $ARG1$; $ARG2$; $ARG3$; exit $LastExitCode | powershell.exe /noprofile -command -

The following directives need to be under the [NRPE] section, NOT under [NRPE Handlers section]:

Code: Select all

allow_arguments=1
allow_nasty_meta_chars=1

Also, I believe these two commands:

Code: Select all

command [check_Visa_Session_Count_Neg]=cmd /c echo scripts/netsta_review_Neg $ARG1$; $ARG2$; $ARG3$; exit $LastExitCode | powershell.exe /noprofile -command -
command [check_Visa_Session_Count_Pos]=cmd /c echo scripts/netsta_review_Pos $ARG1$; $ARG2$; $ARG3$; exit $LastExitCode | powershell.exe /noprofile -command -

need to be under the [External Scripts] section.

After saving the changes in the NSC.ini file, you need to restart the NSClient++ service, so that changes can take effect.

Let us know if this helped.

Hi,
We modified as suggested. we are getting error as below in nagios command line :

UNKNOWN: No handler for that command

[lmiltchev]

I believe you are getting this error because you haven't enabled the external scripts module. Change the line below in the NSC.ini file from this:

Code: Select all

;CheckExternalScripts.dll

to this:

Code: Select all

CheckExternalScripts.dll

save, exit, restart the NSClient++ service, and test your check again.
