Interpreting Plots

SRM creates the following plots to track how well work is being processed:

• System paging delay plot
• Period MPL delay plot
• Period ready user average plot
• Period swap delay plot
• Period paging rate plot
• Period proportional aggregate speed plot
• I/O delay plot
• Queue delay plot
• Address space paging plot
• I/O velocity plot
• Buffer pool hitratio plot

All plots except the address space paging plot are “one-curved” plots where one variable is plotted against another. The address space paging plot is a “three curved” plot where one variable is plotted against three variables.
