NRPE Woes Monitoring Windows Servers

[Nick Price]

Hi


You need to check the following is uncommented

allow_arguments and it should = 1

port=5666 if you are using NRPE
port=12489

did you also add allowed_hosts=   you need to add here the Nagios server IP
address

hope this helps

Nick

Sorry about the lack of info:

I've turned on log debugging and it produced the following:

2012-01-29 09:39:03: debug:NSClient++.cpp:1106: Injecting: CheckVersion: 
2012-01-29 09:39:03: debug:NSClient++.cpp:1142: Injected Result: OK
'0.3.8.75 2010-05-27'
2012-01-29 09:39:03: debug:NSClient++.cpp:1143: Injected Performance Result:
''
2012-01-29 09:39:15: error:modules\NRPEListener\NRPEListener.cpp:393:
Request contained arguments (not currently allowed, check the
allow_arguments option).
2012-01-29 09:39:15: error:modules\NRPEListener\NRPEListener.cpp:365:
NRPEException: Request contained arguments (not currently allowed, check the
allow_arguments option).

In the above case the Nagios command issued was:

./check_nrpe -H <server IP> -p 5666 -c CheckUpTime -a MinWarn=1d MinCrit=12h

I'm aiming to get to a point where for all Windows machines (Servers and
PCs) I have a default check template of:

NSClient++ version
Uptime
CPU Load
Memory Usage
Disk Usage (all partitions)
Explorer process is running.

In the NSC.ini file, the following have all been uncomment:

FileLogger.dll
CheckSystem.dll
CheckDisk.dll
NSClientListener.dll
NRPEListener.dll
SysTray.dll
CheckEventLog.dll
CheckHelpers.dll
CheckWMI.dll
;
; Script to check external scripts and/or internal aliases.
CheckExternalScripts.dll

Also:

allowed_hosts=<Nagios Server IP Address>



Regards,
Rab.

Yes, it is rather.

Does the nsclient.log file contain anything interesting?

There are umpteen ways to configure NSClient++ and run checks against it.
What specific checks are you trying to run and how are you running them?
