But yes, this is what I am asking.
Metrics will be gathered every 30sec to 20min depending on what metric and what the user
needs
(actually users would like to see even much shorter intervals).
Always sending whole configuration too puts a lot more stress on the AS, the HC/DC , the
network
etc.
Ok, maybe i should have explained better - Currently we have an
operation which returns the configuration of a resource and can
optionally contain metrics (this might be more useful to other clients
than RHQ). Additionally we have a single read attribute operation -
which can be used to retrieve a single metric value.
We can certainly add a 'query-metrics' operation which will only return
the metrics for a given resource. Additionally you will have the option
to do a 'composite operation' of multiple single read attribute queries
you are interested in.
