Host Groups in hobbit-alerts.cfg as per BB? 🔗 link

Is it possible to create "host groups" for alerting as per the
bbwarnsetup.cfg and bbwarnrules.cfg files in Big Brother?

The hobbit-alerts.cfg file mentions I can use regular expression type
wildcards, but some servers for which I want the same alerting do not
follow any such pattern.  Does using "%hostA1|hostA2|hostB3|otherhost" fake
the grouping?

TIA,
Andy.

Yes. There are actually two way you can do that - the documented
one, and the simple one :-)

That's the documented way of doing it, yes. Although your example is
not quite correct - it should be "%(hostA1|hostA2|hostB3|otherhost)".

The simple way is this: "hostA1,hostA2,hostB3,otherhost"

Note: You cannot mix the two - it's either a regular expression,
or a simple list.

Is it also possible to have page groups setup the same way?

as in:

HOST=* SERVICE=conn REPEAT=10 RECOVERED
MAIL=
"user-bb555dc64cde@xymon.invalid,user-f5cd6d1f5b53@xymon.invalid,user-53ac79997b90@xymon.invalid" DURATION>30 COLOR=red

Yes. The parameter after the MAIL keyword is passed directly to the
"mail" command, so assuming your "mail" utility supports it, then
a comma-separated list of recipients should work. I think all Unix
"mail" implementations allow that.

I'm trying to migrate from a large BB installation which made extensive use of host groups via the BBConfigure script.  While some of the groups would allow for a regex to describe its members, there are quite a few sizable groups where this isn't feasible.

Is there any way hobbit could support the bbwarnsetup.cfg file style of host groups?  Or possibly the HOST (and MAIL arguments for that matter) could accept shell commands somehow?

For example:

HOST=`/usr/local/bin/bbgroup netapps`
	MAIL `cat oncall.txt`

(And bbgroup would assemple a comma seperated list of netapp hosts.)

Though I suppose the SCRIPT keyword would allow something similar for mailing.

Thoughts?

I doubt that. PCRE's are extremely flexible, see below.

No. Frankly, I think this would be unnecessary bloat, because it is
fairly easy to do a script that converts the bbwarnsetup hostgroup
definitions into Hobbit macros that can be used directly in the alert
definitions.

I've attached such a script - it appears to work on the
bbwarnsetup.cfg I have, but there might be some special cases with
bbwarnsetup features I dont use.

E.g. if you have a definition like this one

hg-asd: mwsicha* asp* mwscsg* slsportal* asdad* asdnam* asdmgmt*

the script outputs a macro definition:

$HG-ASD=mwsicha(.*)|asp(.*)|mwscsg(.*)|slsportal(.*)|asdad(.*)|asdnam(.*)|asdmgmt(.*)

Put this in your hobbit-alerts.cfg, and you can define rules like
this:

HOST=%$HG-ASD
	MAIL user-ef86c43926b6@xymon.invalid SERVICE=http

etc.


(I admit - it's untested, but it should definitely work. The
expression at least is correct, and matches the hostnames it is
supposed to match).

You mean put the above macro definition in the hobbit-alerts.cfg file?
