Hello, I'd like to discuss IGNITE-1071 IgniteCache.metrics() method returns local metrics <https://issues.apache.org/jira/browse/IGNITE-1071>
I agree to make IgniteCache.metrics() global but want to keep MBeans local. According to specification: An MBean can represent a device, an application, or any resource that needs to be managed. So, I think it's a good point that MBean represents node instead of cluster. I case we will make MBeans global (representing whole cluster) we have no chances to see metrics of specific node which can be interesting for some reasons. For example - per node cachePuts metric can show is there any problems with affinity function or hashCode collisions. Val, Semen, could you please explain reasons of MBeans refactoring? We will loose api to gain per node metrics in this case. Thoughts?
