8.15 HP Utility Meter User's Guide (January 2010)

The frequency of usage reports sent from the Utility Meter to HP are:
• For PPU: 48 times per day per partition
• For URS: 12 times per day per disk array; 4 times per day per SAN switch
1.8 Missing Usage Reports
IMPORTANT: HP requires that an email address is configured and monitored as the Utility Meter's system
contact. This ensures that HP can send a notification email to the customer in case HP does not receive PPU
or URS usage reports from the Utility Meter.
You can have up to 10 email addresses for the Meter Contact Email. An email alias or distribution
list, which can contain more than one single person's email address, is recommended so that the email
address can be managed independently from the Utility Meter's configuration data. For details about
configuring a Utility Meter system contact, see Section 2.6: “Configuring the Utility Meter Parameters”.
PPU and URS usage reports are written to the /var/opt/meter/sent directory. The Utility Meter system
retains the last 90 days of usage reports. For a complete history of your usage reports, go to the Utility
Pricing Solutions (UPS) Web portal. (For details of the UPS portal, see Section 1.6: “Utility Pricing Solutions
Web Portal”.)
HP computes the average system usage per day. If on any given day usage data was collected for a minimum
of 23/24 percent of the time the meter was running, the PPU or URS computing resources are considered
to have sufficient usage data to compute the daily average. If HP does not receive sufficient data, the missing
data rule is triggered.
Depending on the type of HP Utility contract (PPU or URS), the following usage is billed:
• PPU — For the first 14 calendar days of missing data, the missing data is copied from the last day HP
could compute usage. After 14 days, HP assumes 100% utilization for PPU computing resources that
did not report usage.
• URS — The missing data is copied from the last day HP could compute usage for URS resources (disk
arrays or SAN switches).
If, for whatever reason, HP does not receive PPU or URS usage data for two consecutive days, the Utility
Meter system contact is notified through email and HP applies the missing data rule to derive usage for the
PPU or URS resources. At the same time, a support case is logged within HP for the problem. An HP support
representative will contact the customer regarding the issue.
You can use the Utility Pricing Solutions Portal (http://www.hp.com/go/payperuse) to determine whether
HP is receiving usage data or if the missing data rule has been applied for a particular day.
IMPORTANT: It is imperative that the customer works with HP to repair any communications breakdown
so that an accurate invoice is delivered to the customer.
Most often a problem occurs after one of the following situations:
• A new PPU WBEM partition was created without installing the required WBEM components.
• A new PPU Agent partition was created without installing the PPU Agent software on the partition.
• A new PPU WBEM partition was created, the required WBEM components were installed, but the
partition was not configured for being metered at the Meter device. For details, see Section 4.7.1:
“Verify PPU WBEM Partition/Server Configuration”.
• A new PPU Agent partition was created, the PPU Agent software was installed, but not properly
configured by using the appropriate command on the PPU partition. For details, see Section 4.7.2:
“Verify PPU Agent Configuration”.
• The PPU WBEM partition configuration information has changed since the PPU WBEM Partition/Server
was added using the Utility Meter GUI.
• The WWN of the management board of the switch has changed since the switch was added using the
Utility Meter GUI.
• A network configuration, for the network that the Utility Meter is installed on, has been changed.
