Disk Cache Change Analysis
This report identifies the dynamic server processes running during the measurement, as
follows:
Disk Cache Change Analysis
Example 4-45 is a detailed report displaying the disk cache change analysis.
The disk cache change analysis factors are the following:
(1) Program File Name: The full file name of the dynamic server.
(2) AVG Cnt: Number of dynamic servers running.
(3) AVG Pri: Average priority of this server.
(4) AVG Mem Pages: Average number of memory pages for this server.
(5) AVG Cpu Pct: Average percentage of CPU time busy for this server.
(6) AVG Disp Rate: Average dispatch rate of this server.
(7) AVG Msg Rate: Average message rate of this server.
(8) AVG R/S Ratio: Average ratio of the received and sent messages.
(9) AVG Ms/R Ratio: Average cost in milliseconds of CPU time per received
message.
