correctly. Related discussion:

> Implement replacement for obsolete CacheMetrics#getOffHeapAllocatedSize
> -----------------------------------------------------------------------

> Key: IGNITE-5490
> URL: https://issues.apache.org/jira/browse/IGNITE-5490
> Project: Ignite
> Issue Type: Improvement
> Components: cache
> Affects Versions: 2.0
> Reporter: Ivan Rakov
>
> With new 2.0 architecture, many caches can share one memory policy. Memory
> metrics allows to measure memory usage (loaded pages) for the whole policy.
> However, there's also a need to measure how much memory (or pages) is used by
> each cache.
> Before 2.0 such information was accessible with
> CacheMetrics#getOffHeapAllocatedSize, but current implemetation returns 0.
> We should either implement it or provide alternative metrics (e. g.
> approximate number of loaded pages per cache). Please note that precise
> number of loaded pages per cache is not defined - one page can contain
> entries of different caches.
