Buffer Pool Hitratio Plot

SRM uses the buffer pool hitratio plot to keep track of the relation between the size of the buffer pool and the hitratio of DB2® buffer pool accesses. The hitratio is percentage of hits, when looking for data in the buffer pool, related to the total number of attempts to read data from the buffer pool. There is one plot per buffer pool.

Buffer Pool Hitratio Plot

x axis
The size of the buffer pool in Megabytes. This is not the absolute size of the buffer pool, instead this is the delta to the defined minimum size.
y axis
The hitratio.
