Subject [jira] [Commented] (IGNITE-49) Implement statistics and management
Date Thu, 22 Jan 2015 18:52:35 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-49?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14287965#comment-14287965

Dmitriy Setrakyan commented on IGNITE-49:

Additionally, after consulting with Yakov, I think that ClusterNode should continue to return
ClusterMetrics as a snapshot (I was wrong in my initial suggestion that it should be ClusterNodeMetrixMBean).

So, to summarize:
# {{IgniteCache.metrcis()}} should continue to return {{CacheMetrics}} snapshot
# {{IgntieCacheMxBean}} should inherit from {{CacheStatisticsMxBean}} and return current values
(not snapshot) together with additional cache management functionality we have.
# We should add method {{IgniteCache.mxBean()}} which will return {{IgniteCacheMxBean}}
# {{ClusterNode.metrics()}} method should return an instance of {{ClusterMetrics}} snapshot.
# {{ClusterNodeMetricsMBean}} should become {{ClusterNodeMetricsMxBean}} and continue to work
as before.
# We should also probably rename all MBean classes to MxBean (Yakov, please comment if you
disagree here)

> See CacheMXBean, CacheStatisticsMXBean. Note: statistics/management can be enabled/disabled
at runtime, also see spec '12.4. Statistics Effects of Cache Operations', need to check if
it is consistent with current GridGain metrics.
