Nagios Support Forum

Hi everyone,

I'm running on a single monitor host:

Nagios 3.5.0
Ubuntu 12.04
NRPE 2.14
Nagios Plugins 1.4.16

I'm trying to get the Check All Services.wsf script (http://tinyurl.com/nbsq75c) working. I've defined this command in commands.cfg:

define command{

You did not list if you are using NSClient++ or what version, this is a windows check so we would need to know that portion, as well as your command and service definitions for this check, and the nsclient/nsc.ini file's command definition for this plugin from the window server.

Checks all automatic Windows services are running. Accepts exclusions. Written Natively to work on any modern Windows system and can be used with any standard Nagios remote execution method.

Thanks slansing. I submitted the post in error halfway through writing it. Doh!

I'll get more info when in the office tomorrow.

Sounds good! Let us know.

Hi slansing. I have some more info for you:

My commands.cfg has the following command definition:

define command{
command_name check_nrpe
command_line /usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}

I've this service definition for the remote host I want to monitor:

define service{
use generic-service
host_name gbflwmgm01
service_description All Services
check_command check_nrpe!check_all_services_wsf
}

In the nsclient.ini file on the (Windows) remote host I want to monitor I have this:

[/settings/external scripts/alias]
check_all_services_wsf=cscript //NOLOGO c:\nagios\check_all_services.wsf

However, in the Nagios console the All Service check is listed for the remote host, but its status is UNKNOWN and Status Info reports 'No handler for command: cscript'. If I run the script manually on the Windows box, it runs ok and reports 'x automatic services running', etc.

Any ideas? Many thanks in advance as this problem is driving me mad

Hmm, it would be easiest to move the check_all_services.wsf script to the nsclient++\scripts directory, then modify the nsc.ini external script listing to this:
Restart nsclient++ and you should be fine!

Hi. Yeah I tried that and it didn't fix the issue. I've been digging in further to try and fix this and found out the following...

From the monitoring server, if I run the command check_nrpe -H <client IP> I get the response
I (0,4,2,90 2013-02-04) seem to be doing fine. So, communications look ok between the 2 computers.

However, if I run any other check_nrpe command from the monitoring server e.g.
./check_nrpe -H <Client IP> -c check_time then I get the same error as I see in the Nagios GUI - No handler for command:....... I can run check_nt commands no problem, so the NRPE looks to be problem.

I'm wondering if this is a problem with the Nagios/NRPE server configuration and not with the client I'm monitoring? I set up same external script check on a 2nd client computer and got the same errors.

Any other ideas?

Well that error is stemming from definitions on the remote host, can you post your nsc.ini file in code wraps and block out front facing IP's and your password?

Post the NSC.ini (nsclient.ini) file, so that we can take a look at it (obscure the sensitive data).

Thanks guys. Here is my nsclient.ini file:

# If you want to fill this file with all avalible options run the following command:
# nscp settings --generate --add-defaults --load-all
# If you want to activate a module and bring in all its options use:
# nscp settings --activate-module <MODULE NAME> --add-defaults
# For details run: nscp settings --help
