Good afternoon,
I have defined the following 4 commands:

#Alert if Explorer.exe PROCESS is NOT running on WINDOWS hosts using check_nrpe
define command{
        command_name check_nrpe_explorer_off
        command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -p 5666 -c check_process process=explorer.exe "crit=state = 'stopped'" warn=none
}

#Alert if Explorer.exe PROCESS IS running on WINDOWS hosts using check_nrpe
define command{
        command_name check_nrpe_explorer_on
        command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -p 5666 -c check_process process=explorer.exe "crit=state = 'started'" warn=none
}

#Alert if IIS SERVICE is NOT running on WINDOWS hosts using check_nrpe
define command{
        command_name check_nrpe_IIS_off
        command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -p 5666 -c check_service service=W3SVC "crit=state = 'stopped'" warn=none
}

#Alert if IIS SERVICE IS running on WINDOWS hosts using check_nrpe
define command{
        command_name check_nrpe_IIS_on
        command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -p 5666 -c check_service service=W3SVC "crit=state = 'started'" warn=none
}

that are respectively referenced by the following 4 services:

Code: Select all

#check_nrpe alert if Explorer Is NOT running
define service{
    use                 generic-service
    #host_name           MN2GAM12099U
    hostgroup_name      099U
    service_description NRPE_Explorer_Not_Running
    check_command       check_nrpe_explorer_off
}

#check_nrpe alert if Explorer IS running
define service{
    use                 generic-service
    #host_name           MN2GAM12099U
    hostgroup_name      099U
    service_description NRPE_Explorer_Is_Running
    check_command       check_nrpe_explorer_on
}

#check_nrpe alert if IIS/W3SVC is NOT running
define service{
    use                 generic-service
    #host_name           MN2GAM12099U
    hostgroup_name      099U
    service_description NRPE_IIS_Not_Running
    check_command       check_nrpe_IIS_off
}

#check_nrpe alert if IIS/W3SVC IS running
define service{
    use                 generic-service
    #host_name           MN2GAM12099U
    hostgroup_name      099U
    service_description NRPE_IIS_Is_Running
    check_command       check_nrpe_IIS_on
}

to check if the process Explorere.exe and the service W3SCV are or are not running.
Nagios Core 4.3.4 verifies OK, but in the GUI, the application services both return "OK: all processes are ok." and the process services both return "OK: All 146 service(s) are ok.", so it looks as though the parameters to specify explorer.exe and w3svc are being ignored.

Also, from the command line, ./check_nrpe -H 99.99.99.99 --command check_service service=nscp also returns: "OK: All 146 service(s) are ok."
Again, the part of the command specifying the service is ignored.

Can anyone suggest where I might be going wrong?
Thanks in advance and Happy New Year to all!
Pete

Which version of NSClient++ is running on the Windows machines? This is important because many of the native NSClient++ commands are different between 0.3, 0.4, and 0.5. One parameter may work on 0.3 but be completely gone in 0.5. Though I don't think that's the problem, It's worth mentioning.

Try passing the NSClient++ arguments with the check_nrpe -a parameter. Like so:

Code: Select all

./check_nrpe -H 99.99.99.99 --command check_service -a service=nscp
./check_nrpe -H 99.99.99.99 -p 5666 -c check_service -a service=W3SVC "crit=state = 'started'" warn=none
./check_nrpe -H 10.25.14.10 -c check_service -a service=RemoteAccess "ok=state='stopped'" "warning=not state='stopped'" "critical=not state='stopped'" "perf-config=*(ignored:true)"

Thanks for coming back to me!
It's 0.4.3.143
Adding -a returns the following:
./check_nrpe -H 99.99.99.99 check_service -a service=nscp
I (0.4.3.143 2015-04-29) seem to be doing fine...

./check_nrpe -H 99.99.99.99 check_service -a service=W3svc
I (0.4.3.143 2015-04-29) seem to be doing fine...

so again ignoring the specified service.

Cheers

Be sure to include the -c flag when passing a command to NSClient++ via check_nrpe. Like so:

Code: Select all

./check_nrpe -H 99.99.99.99 -c check_service -a service=nscp

I just realised that I hadn't included -a in my command definitions - adding that in and restarting Nagios makes things work fine!

Thanks very much for the hint about the differences between different versions of NSClient++ - that's what got me sorted!
