HP XP Performance Advisor Software - Manual (Page 318)

you
can collect the real-time performance data for a set of five LDEVs, RAID groups, ports, cache,
and
MP blades in an P9500 and XP7 disk array. This data is collected for a set of real-time
metrics
that HP XP7 Performance Advisor supports. When you start a real-time performance data
collection
for an XP or an XP7 disk array, the following sequence of steps follows:
1. The
associated host agent collects real-time performance data from the XP or the XP7 disk
array and sends the data to HP XP7 Performance Advisor.
2. HP XP7 Performance Advisor plots a graph of the real-time performance data points. This
process continues till you stop the real-time data collection.
IMPORTANT:
•
Real-time
monitoring is supported for the XP7 disk arrays and the following XP disk array
models:
P9500, XP24000, XP20000, XP12000 and XP10000.
•
Real-time
monitoring can be initiated on multiple XP and XP7 disk arrays.
•
The
configuration data for an XP or an XP7 disk array is maintained by HP XP7
Performance
Advisor on the management station. The same data is also maintained by the
real-time
server on the HP XP7 Performance Advisor host. Ensure that both these instances of
configuration
data are the latest.
•
By default, the real-time server on the HP XP7 Performance Advisor host agent uses port 8331
to communicate with the management station. This port number is stored in the
xprmihaserver.properties
file.
◦ On the management station, the xprmihaserver.properties file is located in the
hpss/pa/properties
folder.
◦ On the host agent, the xprmihaserver.properties file is located in the xppa/
realtime/config
folder.
However, if you want to use a different port, complete the following steps:
1.
On the management station, open the xprmihaserver.properties file in a text
editor.
2. Update the new port number or the default port number in the Port.Number field.
3. Restart the HP XP7 Performance Advisor service on the management station.
4. On the HP XP7 Performance Advisor host agent, open the xprmihaserver.properties
file in a text editor and repeat step 2.
5. Restart the HP XP7 Performance Advisor host agent service.
You can also restore the default port setting to 8331 using the above-mentioned steps.
