Michael,
Thank you for the link. Unfortunately, the regex doesn’t work
either. If my config is:
apply Service "Disk Space - /partition" {
import "disk-check"
vars.nrpe_remote_arglist = "10% /partition"
assign where regex("^App 1 Name.*", host.groups)
}
I will see:
warning/Service: Apply rule 'Disk Space - /partition' for host does
not match anywhere!
In the checkconfig output.
If I spell out the full name of the host group like this:
apply Service "Disk Space - /partition" {
import "disk-check"
vars.nrpe_remote_arglist = "10% /partition"
assign where "App 1 Name DBs" in host.groups
}
The error goes away and the disk check appears on the correct machines.
While this workaround works, it would be much easier to manage over
time if either the match() rule or the regex() rule worked.
Can you confirm if this is a bug, in which case I’d be glad to file a
ticket, or if this is working as designed, or equally possible, I have
no idea what I’m doing and have mucked up the configuration. If the
latter is true, I’d appreciate the above code block being corrected.
I cannot confirm this being a bug or not, I just don't have time to test
it now for myself. If you think it is one, and it looks like one, please
do so in opening one at dev.icinga.org
But please be advised, that we don't immediately answer/comment/handle
bugs. We'll keep them reviewed in our weekly dev meetings though.
Also, for regex(), what type is it? Is it Perl or Java or something else?
Don't really get what you mean by that. If you want to know how regex()
as function is evaluated, look into the source code ;-)

kind regards,
Michael
Thank you.

Is there any documentation on when and how you can use “assign
where match”? I’m trying to do something like the following:
apply Service "Disk Space - /partition” {
import "disk-check"
vars.nrpe_remote_arglist = "10% /partition"
assign where match ("App 1 Name*", host.groups)
}
In our environment we have a number of host groups that start with
the same application name but end with something unique such as
“App 1 Name Web”, “App 1 Name DBs”, “App 2 Name Web”, “App 2 Name
DBs”. I want to check for a shared partition that is unique to
all the “App 1 Name” machines but is different than the data
partition that is unique to all “App 2 Name” machines.
This exact type of assign statement works fine for “object
HostGroup” blocks.
If “assign where match” doesn’t work in the “apply Service” block,
is there another shorthand way to locate my groups or do I have to
list each group specifically and manage that list over time?
Maybe regex() fulfills your requirement better than match().

Thanks for your help.
