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

             Summary: Implement cache size metric in bytes
                 Key: IGNITE-12507
                 URL: https://issues.apache.org/jira/browse/IGNITE-12507
             Project: Ignite
          Issue Type: Improvement
          Components: cache
            Reporter: Ivan Rakov
             Fix For: 2.9


There is a need to have cache size in bytes metric for pure in-memory case.

When all data is in RAM, it is not obvious to find out exactly how much space is consumed by cache data on a running node as the only things that could be watched on is number of keys in partition on a specific node and memory usage metrics on the machine.
