[Nagiosplug-help] Macros not evaluated in hostextinfo definition?

[Ralph.Grothe at itdz-berlin.de]

Hello all,

I apologize for posting my question about a basic nagios
configuration question
relatively unrelated to nagios plugins rather here than in the
nagios users' list.
But the knowledgeable members of this list seem to be much more
supportive
I have experienced, which I hereby shamelessly exploit.

I defined something like the below in various hostextinfo blocks.
The notes_url should direct to the useful Perl based ISA tool for
Informix databases.
Because the uri is base64 authentication "protected" I would like
to make use of
a few macro definitions to avoid hard coded credentials appearing
in clear in the nagios config files.

So the $USER15$ contains these credentials as expected as a
string of "username:password".
As you can see I also refer to an on-demand macro definition
"HOSTADDRESS:somehost$
which refers to the primary cluster node that hosts that
respective db instance as a cluster package.
$USER17$ simply contains the port the ISA webserver is listening
on.
And finally, the sole query path argument value contains the db
instance.


define hostextinfo {
    ...
    notes_url
http://$USER15$@$HOSTADDRESS:somehost$:$USER17$/isa/bin/summary.p
l?env=some_ids_inst
    ...
}


Unfortunately nagios isn't expanding the macros as I would have
wished.
Instead it simply omitted any substitutions and made up this sham
url:

http://:/isa/bin/summary.pl?env=ahw32_shm


So I guess that macro substitution is generally not supported in
hostextinfo context.
Is there another way how to configure this then without hard
coding the exact urls?

Regards

Ralph
