Performance Analysis Facility/VM
Performance Analysis Facility/VM helps in analyzing system performance. It provides statistical information and interactive graphics to help identify patterns in system performance for VM/ESA systems. VMPAF also allows you to view data from multiple systems. This can be used to compare data from the same system before and after changes have been made.
The interactive graphics environment shows how performance variables behave over time. It also provides statistical information about these variables, including minimum, maximum, and average values for the time period. The program calculates the coefficient of correlation between each of these variables and a variable representingthe quality of performance that users are experiencing.
VMPAF uses VM performance data as input. It processes output data files from:
- VM Performance Reporting Facility (VMPRF, 5684-073)
- VM/ESA Realtime Monitor (RTM/ESA, 5798-DWD)
- VM Monitor Analysis Program (VMMAP, 5664-191)
- VM Realtime Monitor (VM/RTM, 5796-PNA)
For year 2000, the VMPAF product tape was updated in 1996. Please reorder it if you received it prior to 1997.
