NAME
ppu - Pay per use software for HP-UX
DESCRIPTION
Pay per use (PPU) is a program under which customers pay only for computing capacity that they use. The PPU software provides services for
metering resource utilization on supported HP systems. Depending on the type of contract a PPU system is under, utilization can be either
of the actual percentage utilization of each core, or a count of the number of active cores in the system. The PPU software communicates
with a utility meter to report utilization data. The utility meter in turn transmits the utilization data to HP for proper billing.
PPU systems must be configured to use a utility meter. Utility meter configuration is accomplished using the command (see ppuconfig(1M)).
The data that is sent to HP is aggregated and sent to billing; it is also posted on the Utility Pricing Solutions portal for viewing at
http://www.hp.com/go/payperuse.
PPU can be run in an HP Integrity Virtual Machines environment (HPVM). In this case, the usage information for billing purposes is still
the overall usage for the VM Host. However, you can examine the usage report at the portal to see a detailed breakdown of the usage for
each virtual machine (also called a "guest").
In an HPVM environment, PPU needs to be installed and configured only on the VM Host, not on the guests. The command will report an error
if invoked on a VM guest.
