https Client The https client, which runs on the PPU system as a daemon, reports
the following information to the utility meter:
• System-identification information
• Hardware-partition information
• Virtual-partition information
• Per-processor utilization information for the operating system
instance
You interact with the https client only when entering configuration
information. The https client does not require a web server or additional
web components for its operation.
IMPORTANT If the https connection to the utility meter is broken, the PPU system
may be assumed to have 100% processor utilization.
Utility Meter To track the actual processor usage, the utility meter receives reports
from the https client. The utility meter consists of hardware (generally
an IA-32 system) connected to your network and pre-loaded with HP
software. The utility meter is installed and configured by your HP
service representative. One utility meter is required per 100 PPU
systems or partitions.
Usage Database The usage database receives information from the utility meter. The
information is then aggregated and posted to the PPU web portal for
your viewing. See “PPU Web Portal” on page 36 for details on the PPU
web portal.
NOTE If usage data for any partition in the PPU system is not received for any
given day, an e-mail notification is sent to your PPU system contact’s
e-mail address. This e-mail address is configured in the utility meter’s
initial set-up.
