creating a macro made of macro's in hobbit-alerts.cfg 🔗 link

Is it possible to create some macros of hosts, then bundle combinations of those smaller macros into larger ones?

Say I have 3 groups of systems:

$DB=%(db1|data1|dbase).domain.com

$MAIL=%(mail1|smtp|webmail).domain.com

$WS=%(ws1|fred|wilma).domain.com

I'd like to make 2 macros of those systems, one for critical systems, the other for everthing on my network:

$CRITICAL=%($DB|$MAIL)

$ALL=%($DB|$MAIL|$WS)

Then use only the variables $CRITICAL or $ALL as my HOST=<variable name> entry.

If this can be done, I'm having problems getting the syntax right.  Any pointers?

Thanks,
Tom

I could benefit from this too. What I found out is that it does not like
macro made out of macro.

Thanks

It's supposed to work, yes. And yes - there's a bug in how this is
handled. You need the attached patch first.

When doing this, remember that the macros are simple text-substitutions.
So I'd leave out the "%" in the macros, because you end up with too many
of them they way you have it. Instead, I'd do it like this:

   $DB=(db1|data1|dbase).domain.com
   $MAIL=(mail1|smtp|webmail).domain.com
   $WS=(ws1|fred|wilma).domain.com

   $CRITICAL=($DB|$MAIL)
   $ALL=($DB|$MAIL|$WS)

   HOST=%$CRITICAL
      MAIL user-590e80d9822c@xymon.invalid

If in doubt, you can always run "hobbitd_alert --dump-config" to see
what your configuration ends up with - it shows the configuration after
expanding the macros.

Thanks for the patch and the tip on grouping.  I've got nested macros working now, and it has really cleaned up my hobbit-alerts.cfg file!  :)
