I was watching jconsole= behavior...can tell me where exactly I can find "=A0 RecentHitRate= s" :

Tuning for Optimal Caching:

Here they have g= iven one example of that=A0 http://www.datastax= .com/docs/0.8/operations/cache_tuning#configuring-key-and-row-caches ....RecentHitRates...=A0 In my jconsole within MBean I am unable t= o find that one.....=A0
what is the value of long[36] and long[90].....=A0 From Jconsole attributes= how can I find the=A0 performance of the casssandra while stress testin= g?
Thank You
