Cache Statistics
The following statistics are collected for the Cache MBeans:
- Count of each cache operation - current, acquired, and released
- Count of hits and misses for each cache
The Cache MBeans includes the following three categories:
- Distributed
- Local
- Near
These categories list a summary of operations for each cache and provide cache performance. You can reset the counts provided for each cache using JMX operations on the MBean.
Each cache in these categories lists the following common attributes:
