The performance metrics are based on simple counters and values that are set by OpenAccess. At regular intervals a snapshot of all of the counters is captured into a buffer.
The available metrics are grouped into related categories and described in this section.

Mem Free KB and Mem Total KB are the most important metrics to monitor in this category. If the 2nd level cache is too large you may eventually run out of memory.
