                 Key: SAMZA-1161

             Project: Samza
          Issue Type: Improvement
            Reporter: Shanthoosh Venkataraman
            Priority: Minor


Rocksdb LocalStoreMonitor is responsible for clearing up unused/stale local task partition stores in a yarn Node Manager. Metrics are required to understand the behavior of this monitor in production(especially when it's clearing up unused rocksdb local stores).

The following two metrics will be emitted from this:

a) Total disk space cleared in bytes.
b) Total number of rocksdb task partition stores cleared.
