[OASIS Issues Tracker <workgroup_mailer@lists.oasis-open.org>]

Alex Heneveld commented on CAMP-9:
----------------------------------

When discussed at the F2F there seemed general consensus that:

* OPERATIONS (effectors) on components ARE something for which the API spec should define a means to explore and invoke. Including a callback/webhook mechanism was recommended, as Tobias notes above.  Alex (me) to submit a draft proposal.  Others welcomed to contribute -- post here or ping me.

* SENSORS/METRICS can be treated as custom attributes and so do NOT merit further investigation at this point.

> I'd like to be able to discover and access available sensors (or metrics or attributes) and available effectors (operations) on components in my application.
> For instance a WebServer might expose totalRequests as a sensor and updateWar(url) as an effector. It would be nice to be able to list these, query/subscribe to sensor values, and invoke effectors.
> (I like the autonomic computing terminology -- sensor/effector -- but happy to follow JMX terminology -- attribute/notification/operation -- or others.)
> This was raised by Alex Heneveld and was drupal issue # 1061
