Description
The totalHitCount and totalMissCount values jump by 2 for each hit/miss operation instead of jumping by 1.
Below are the steps:
- Create a partitioned region with statistics enabled.
- run gfsh>show metrics and note the values of totalHitCount and totalMissCount
- Put an entry into the region retrieve it using get and check the totalHitCount. The value would have doubled.
- Run a get on a key that is not in the region, and check the totalMissCount, it would have doubled.
