2.3.6 Examples of using Agent for Platform - PFM in a virtualized system: Determining whether to change virtualized system settings
If there are extra physical resources despite the consumption of a significant amount of resources on a specific guest OS or logical partition, we recommend that you change the virtualized system settings.
PFM - Agent for Platform can be used as a tool to determine these kinds of situations.
The following graph shows a case in which the allocation of processor resources is not sufficient.
Because the processor usage for logical partition A is 100%, the allocation ratio is being switched. However, the processor usage for logical partition A does not decrease, while the processor for logical partition B is not fully used. In cases like this, change the allocation ratio settings.
The following graph shows a case in which the allocation of processor resources is sufficient.
The processor resource ratio is being switched while there are many processes in the queue for logical partition A. As a result, the number of processes in the queue for logical partition A is decreasing.
