Yes, based on that doc, as it's the only place that talks about regex or
wildcards.
Elsewhere in our configs, we had a *-do-not-page that worked fine with the
use_regexp_matching=1. When I set use_regexp_matching to 0, I then got this
error:
Could not find any hostgroup matching '*-do-not-page'
So the statement you made doesn't quite make sense: if you enable regex, you
need to make sure they are valid - '*' is not a valid regular expression, only
a wildcard specifier, if not using regexp matching. note the 'contain' in the
below paragraph.
For the situation I described earlier, setting use_regexp_matching=1 and
setting the dependent_service_description to .* is working. Thank you!
Icinga 1.4 was most likely the stable version at the time that we put it in
place about a year ago or so.
Personally I find the ability to use regex/wildcards needing a bit more
documentation. There are generally good examples throughout the docs, and I
feel like this is lacking how to configure things based on the global settings.

Icinga 1.4.0:
In the main icinga.cfg, we have:

I try to create the following dependency:
define servicedependency {
host_name HOSTA
service_description SERVICEA
dependent_host_name HOSTA
dependent_service_description *
notification_failure_criteria w,c
}
Yet, I get this failure:
Error: Invalid regular expression '*' found while expanding service names in
file '/path/to/file.cfg' starting on line 173. NOTE: regex could be inherited
from a template in a different file.
Based on the docs, '*' is valid. There is no template used, so it's not
hidden somewhere else.
based on which docs? those?

if you enable regex, you need to make sure they are valid - '*' is not a valid
regular expression, only a wildcard specifier, if not using regexp matching.

Regular Expression Matching
The examples we give below use "standard" matching of object names. If you
wish, you can enable regular expression matching for object names by using the
use_regexp_matching config option. By default, regular expression matching will
only be used in object names that contain *, ?, +, or \.. If you want regular
expression matching to be used on all object names, enable the
use_true_regexp_matching config option. Regular expressions can be used in any
of the fields used in the examples below (host names, hostgroup names, service
names, and servicegroup names).
Note
Be careful when enabling regular expression matching - you may have to change
your config file, since some directives that you might not want to be
interpreted as a regular expression just might be! Any problems should become
evident once you verify your configuration.

a single dot, matching all with asterisk should do the trick - but keep in mind
that enabled regex could require changes in your entire configuration.
btw - why 1.4.0 ?
Thoughts?
