-----------------------------------

             Summary: CacheMetrics.getAverage###Time is not calculated properly
                 Key: IGNITE-3495
                 URL: https://issues.apache.org/jira/browse/IGNITE-3495
             Project: Ignite
          Issue Type: Bug
            Reporter: Denis Magda
            Assignee: Andrey Velichko


{{CacheMetrics.getAverageGetTime}}, {{CacheMetrics.getAveragePutTime}} and {{CacheMetrics.getAverageRemoveTime}} are not calculated properly in the following scenario:

- start a server node;
- start a client node that will perform gets and puts;
- {{CacheMetrics.getAverage###Time}} will always be 0 for the server node's cluster group.

The issue happens because {{CacheMetricsImpl.add###TimeNanos}} method is not called on the server side when a metric related event happens.

In the attache you can find source that showcases the bug.

- start basic {{ExampleNodeStartup}} using attached configuration {{example-default.xml}} conjuration;
- start {{ExampleNodeStartupClient}}. You will see that average metrics are not incremented.
