Starting real-time performance data collection
Prerequisites
•
HP recommends that you dedicate a command device for the real-time performance data
collection, so that it is not used by HP XP7 Performance Advisor for the regular configuration
or performance data collection.
•
If
there have been configuration changes on the XP/XP7 disk array for which you want to
collect
the real-time performance data, the following informational message appears when
you
select components and start plotting the real-time graphs:
The
<XP or XP7 disk array> configuration data available in the Real Time Server is not in
sync
with the configuration data available on Performance Advisor. This could occur due to
the
following reasons: Command device is invalid, <XP or XP7 disk array> is no longer
connected,
or selected components are not available on the selected <XP or XP7 disk
array>.
Perform
the following steps to ensure that the same configuration data for the selected XP/
XP7 disk array is available on both the host agent real-time server and HP XP7
Performance
Advisor:
1.
Request a host update. For more information, see
“Requesting host agent updates”
2.
Initiate the configuration data collection from HP XP7 Performance Advisor, so that the
latest
configuration data is available for the XP/XP7 disk array. For more
information,
3.
For the HP XP7 Performance Advisor host agent that is connected to the selected XP or
XP7 disk array, update its real-time server with the latest configuration data of the XP/
XP7 disk array. Click Update RealTime Server on the RealTime screen for the host agent
to
receive the latest configuration data. Updating the real-time server lasts for about 20 -
30
minutes and the following informational message appears after the update is
complete:
Real Time Server Configuration Collection update done for Hostagent. You can then
proceed with the real time data collection and plotting of charts.
