HP XP P9000 Performance Advisor v6.0 Software Troubleshooting and FAQs Guide
Real-time chartingHP XP P9000Watch
Through real-time charting, you can view real-time metrics
collected for RAID groups or LDEVs that belong to an XP
or a P9000 disk array. At a time, you can monitor a
maximum of five RAID groups or LDEVs in an XP or a
P9000 disk array.
I need to monitor response time for a particular RAID group over a shorter duration. Can I collect
performance data for less than 60 seconds using HP XP P9000 Performance Advisor?
No. The minimum duration for collecting performance data using HP XP P9000 Performance
Advisor is at least one minute. To view data for less than a minute duration, use HP XP P9000Watch
or the real-time charting feature in HP XP P9000 Performance Advisor.
Can I view real-time performance graphs for multiple XP and P9000 disk arrays simultaneously?
Yes. You can collect real-time performance data and view real-time graphs for multiple XP and
P9000 disk arrays. However, ensure that the real-time data collections are happening through
dedicated host agents.
For example, if host agent_A and host agent_B are connected to both XP disk array_1 and XP disk
array_2, initiate a real-time data collection on XP disk array_1 through host agent_A and on XP
disk array_2 through host agent_B. You cannot use host agent_A to collect real-time data for both
XP disk array_1 and XP disk array_2.
Can I initiate multiple instances of real-time data collections for an XP or a P9000 disk array, or
multiple XP and P9000 disk arrays using the same host agent?
No. You cannot initiate another instance of real-time data collection using a host agent that is
already collecting real-time data for an XP or a P9000 disk array. At a time, a host agent can only
handle one instance of real-time data collection.
If an XP or a P9000 disk array is connected to two host agents, is it possible to simultaneously
initiate real-time data collections on the XP or P9000 disk array through both the host agents?
Yes. It is possible to initiate real-time data collections on the XP or P9000 disk array through both
the host agents, as each host agent will still be handling only one instance of real-time data
collection.
Can I use a host agent for real-time data collection, if the real-time server is getting updated on
that host agent?
No. Wait for the real-time server update to complete, if you want to use the same host agent for
a real-time data collection.
Can I save a real-time chart for my future reference?
No. There is no option to save real-time charts.
Can I view historic data for an XP or P9000 disk array using the real-time charting functionality?
No. Real-time charting functionality can only be used to view the point in time data for your XP or
P9000 disk array. If you want to view the historic data, use the Charts functionality provided by
HP XP P9000 Performance Advisor.
When real-time charting is in progress, will it be impacted by either configuration or performance
data collections that are happening simultaneously?
No. When real time collection is in progress for an XP or a P9000 disk array through a host agent,
you can still initiate configuration and performance data collections on the same XP or P9000 disk
array through the same host agent, provided you select a different command device. You can also
select a different host agent for the configuration and performance data collections.
Why are XP10000 and XP20000 type disk arrays not listed under Select Components on the
RealTimeCharting screen?
