check_nt checking multiple services using regex

Hello,
Is it possible to use regular expressions in check_nt to see if multiple services are running?
We have a lot of servers running services which all start whit the same three letters, but have different names on all servers.
Instead of creating all these different service check, I would like to create 1 service check to see which services are running starting with the three letters.
Best regards,
Rob Hassing

You should be able to do something like this to match all services that contain YYYYYY
Code: Select all
./check_nrpe -H HOST -u -t 30 -c check_service -a "filter=name like 'YYYYYY'"

When I try the command on the commandline, this works as expected.
But when I try the same command in Nagios XI it fails with: "Failed to validate filter see log for details: Filter expression is not valid: name like \'uds.c\'
I have tried the following as well:
-a filter=”name like \‘uds.c\’”
-a filter=”name like \"uds.c\"”
With the same result.
Does anyone have another suggestion?

Rob,
Is it just failing when you run a test of the command from inside the CCM? There are some commands that just cannot work from there for security concerns, certain chars must be escaped when coming from a web GUI, this command has several of them. If you save the command as I showed you it should just work when Nagios executes it even though it fails through the CCM
