tagging checks about flapjackfeeder

[jessereynolds]

At the moment you can’t add custom tags to be passed by flapjackfeeder, but note that every word in your check definition / name will be created as ephemeral tags on the event in flapjack, also the domain and host parts of the fqdn (eg foo-app-01.example.com creates tags “foo-app-01” and “example.com”)

eg if check name is “HTTP Regex for www.example.com” then you get that split into 4 tags also
‘HTTP’, ‘Regex’, etc

It may be possible to extend flapjackfeeder to create event tags to carry through the servicegroups etc, eg "servicegroup:group_1", "servicegrouop:group_2" etc

Matching hostname is good way but it's not enough.

Are you sure that NEB provides information about servicegroups beacuse I didn't find it defined it here: https://github.com/Icinga/Icinga-core/blob/master/include/nebcallbacks.h

@pulecp sorry no I'm not at all sure that it's possible. I was discussing this with @bs-github yesterday, perhaps he can shed some more light.

[jessereynolds]

@bs-github is now working on this. The plan is to pick up the following custom variables from the Nagios/Naemon/Icinga configuration:

• _tags - containing tags delimited by !
• _initial_failure_delay - in seconds
• _repeat_failure_delay - in seconds

[bs-github]

The code is still not 100%, but a good part of it should be done.

One thing is implemented differently:
For _tags - containing tags delimited by ! the code ignores the !s completely.
But you can use multiple _tags lines instead.

[jessereynolds]

Excellent work.

With _tags - do you mean that Nagios doesn't send through the full value including the !s? Or that you haven't done the split yet?

[bs-github]

I haven't done a split on ! and I do even think multiple _tags lines are more elegant.
Also that already works.
So, I tend to not implement the split thing.

[jessereynolds]

OK. Perhaps we should change it to _tag (singular) then.

[bs-github]

done.
