>                 URL: https://issues.apache.org/jira/browse/IGNITE-3495
>             Project: Ignite
>          Issue Type: Bug
>            Reporter: Denis Magda

> {{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}}
> - start {{ExampleNodeStartupClient}}. You will see that average metrics are not incremented.
