[Hawkular-dev] "Matter" support in Hawkular

[Gary Brown]

Although having "out of the box" canned triggers defined, it may also still be good to provide users with a customisation mechanism to define their own alert triggers - which create "events" for MiQ to consume and react to.

Users could just use the REST APIs - but still may be more user friendly to offer some form of UI. This shouldn't be an issue, if it is considered configuration/customisation of the provider?

Gary
