2.3.14 Virtualized system functionality and collected performance data
In virtualized systems, the setup of provided resources differs depending on how the system is implemented. Also, resource changes might or might not require temporary stoppage of a logical partition. If a logical partition needs to be stopped, this should not affect much because PFM - Agent for Platform is also stopped. However, if a logical partition does not need to be stopped, and the system resources change dynamically, the performance data obtained by PFM - Agent for Platform might be significantly affected. In this case, we recommend collecting performance data not significantly affected by dynamic resource changes.
The following table lists the resources that can be collected for each virtualized system.
