Subject Re: Hit/Miss counts
Date Tue, 02 May 2017 21:46:17 GMT
I think the problem on gfsh show metrics is caused by GEODE-2676. Since it
talks about mbeans it would be helpful if you added to it how it impacts
the gfsh show metrics command.
Currently PartiionedRegions do not support hit/miss count. Vote
for: GEODE-2685.

I think the totalHit/Miss count incing by two instead of one is an unfiled
bug. Internally PRs are implemented by both ParitionedRegion and
BucketRegion. Perhaps each of these is incrementing.
