[Hawkular-dev] "Matter" support in Hawkular

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.
