Feature Request - Support wildcards in exclude arguments

[ne-lgute]

When services need to be excluded, and the service name includes things like version numbers, the exclude argument needs to be changed every time the version number is updated.

Add support for wild cards and/or head/tail type matching rules, so the exclude argument does not need to be changed.

define command {
    command_name check_some_services
    command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -t 60 -c CheckServiceState -a CheckAlc 
    exclude=XYZService122.0.6253.9 exclude=$ARG1$ exclude=$ARG2$ exclude=$ARG3$ exclude=$ARG4$ exclude=$ARG5$
}

Can the number part of this service somehow be matched with regex? I can't figure it out. GoogleUpdaterInternalService124.0.6315.0

[smithmich]

This does not work in Nagios but it does match in regex calculator tests so maybe NRPE doesn't allow this regex expression. GoogleUpdaterService[0-9]{1,3}.[0-9]{1,2}.[0-9]{1,4}.[0-9]{1,2} or ^GoogleUpdaterService[0-9]{1,3}.[0-9]{1,2}.[0-9]{1,4}.[0-9]{1,2}$

Did you try to use the filter argument?

filter=(name not regexp str(GoogleUpdater.*))

[smithmich]

Yes. It doesn’t work with * Not really sure where I would put the filter part though.

Here is what what works for me. To exclude a service by name:

./check_nrpe -H IP_ADDRESS -c check_service -a 'exclude=gupdate'

Lets say the output (CRITICAL) lists both GoogleUpdaterInternalService124.0.6315.0 and GoogleUpdaterService124.0.6315.0

Then I can get rid off those two services with the following regex:

./check_nrpe -H IP_ADDRESS -c check_service -a 'exclude=gupdate!filter=(name not regexp str(GoogleUpdater.*))'

Using NRPE Plugin for Nagios version: 4.0.3

OK I'm getting this error now running Nagios core 4.5.0 Failed to open service filter: 424: The specified service does not exist as an installed service. Here is my check command: It's in test environment but mirrors production with many exclusions.. define command{ command_name check_some_services command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -t 60 -c CheckServiceState -a CheckAll exclude=RemoteRegistry exclude=wuauserv exclude=sppsvc exclude=gpsvc exclude=TrustedInstaller exclude=MapsBroker exclude=gupdate exclude=WbioSrvc exclude=CDPSvc exclude=tiledatamodelsvc exclude=BITS exclude=mfemms exclude=mfevtp exclude=ccmsetup exclude=edgeupdate exclude=WinDefend exclude=vm3dservice 'exclude=gupdate!filter=(name not regexp str(GoogleUpdater.*))' exclude=$ARG1$ exclude=$ARG2$ exclude=$ARG3$ exclude=$ARG4$ exclude=$ARG5$ }

[smithmich]

Update working. I was using the legacy CheckServiceStatus. I switched to the Check_Service and was able to filter the Google services like this: command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -t 60 -c Check_Service -a "filter=name not like 'Google'" exclude=RemoteRegistry exclude=wuauserv exclude=sppsvc exclude=gpsvc exclude=TrustedInstaller exclude=MapsBroker exclude=gupdate exclude=WbioSrvc exclude=CDPSvc exclude=tiledatamodelsvc exclude=BITS exclude=mfemms exclude=mfevtp exclude=ccmsetup exclude=edgeupdate exclude=WinDefend exclude=vm3dservice exclude=$ARG1$ exclude=$ARG2$ exclude=$ARG3$ exclude=$ARG4$ exclude=$ARG5$ #

Hello. Where should i put this filter? Can you provide short manual, please?

[smithmich]

This line is in the /usr/local/nagios/etc/objects/commands.cfg file. On the host I have this to call it: define service { use generic-service ; host_name HOSTNAME ; service_description AllAutomatic Services ; servicegroups Service ; check_command check_some_services!mfevtp!TrustedInstaller ; }
