Hi Anil,

The row (Non heap) does not contains information about cache. If you want
to see how many memory was used by particular cache.

You can switch up metrics for it:

*<bean class="org.apache.ignite.configuration.CacheConfiguration"> *
* <property name="statisticsEnabled" value="true"/>*
...

and tracking a metrics of cache by API:

*ignite.cache("name").metrics().getOffHeapAllocatedSize()*

or by JMX bean.
