2.3.16 Data that can be collected with virtualization systems that use Virtage

Virtage functionality

Like other virtualized systems, the functionality provided by Virtage includes the following:

Virtage manages the above functionality to implement a virtualized system. The logical partition must be stopped to change the virtual network or virtual memory, or to change the number of assigned virtual processors. The logical partition does not need to be stopped to change the virtual processor assignment percentages.

Virtage configuration

Like VMware, Virtage has a parent/child configuration.

To set up a virtualized system on Virtage:

  1. Start the installed instance of Virtage.
  2. Create and set up a virtual machine.
  3. Start the virtual machine.

Using PFM - Agent for Platform on Virtage

Keep the following in mind when using PFM - Agent for Platform on Virtage.

Installing PFM - Agent for Platform
Because Virtage is configured in a special environment called an SVP frame, do not install PFM - Agent for Platform on an SVP frame.
Processor information
Because a virtualized system based on Virtage runs after the logical partition is set up, the number of processors is not changed while PFM - Agent for Platform is running. Accordingly, operation can be performed as usual, but the number of allocated processors might not match the number of processors that physically exist.
Memory
Because a virtualized system based on Virtage runs after the logical partition is set up, the amount of memory is not changed while PFM - Agent for Platform is running. Accordingly, operation can be performed as usual.
Devices
Disk performance data is only for logical partition groups. System-wide performance data that includes the host OS cannot be collected. For the network adapter information, information about network adapters allocated to the guest OS is obtained.
