[Hawkular-dev] "Matter" support in Hawkular

[Heiko W.Rupp]

Hi,

[ I picked "Matter" on purpose in the subject, as the other term (E.) is 
too much overloaded. ]

ManageIQ has Events (going forward I call them ME), that are similar to 
our Alerts.
There are some event parsers that take incoming data and then forward it 
into the
MiQ events system, where automatic actions can be triggered

Now we have a pretty similar concept with our alerts.

For ME on metrics, MiQ pulls the metrics and the provider integration 
creates
the ME on them.

I wonder if for other purposes we can use our existing alerts subsystem
with some "canned alerts", that translate input into such MiQ-Events and
forward them into MiQ.
With "canned" I mean that those are not set up via UI, but rather we
have "trigger templates" that are applied each time a new resource of a
given type is added to inventory.
This implies that those templates can only work on things that do not 
have
a variable threshold like system going up/down, WildFly reporting 
"reload
needed" and so on.

While it would be certainly possible to implement this at the level of 
emitting
inventory "matters" and metric "matters" and so on I think having that 
central
piece of logic to do it - could be better to handle.
