Start/Stop Real-Time Performance Data Collection - HPE XP7 User Manual

IMPORTANT:
• Real-time monitoring is supported for the XP7 disk arrays and the following XP disk array
models: P9500, XP24000, XP20000. Real-time monitoring of metrics is made available in the
following components and features in XP/XP7 arrays: Ports, Host Groups, Processors, Cache,
LDEVs, RAID Groups, THP/SMART Pools.
• PA maintains the configuration data for an XP or an XP7 disk array on the management station.
The real-time server also maintains the same data on the PA host. Ensure that both these
instances of configuration data are the latest.
• By default, the real-time server on the PA 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 PA service on the management station.
4. On the PA host agent, open the xprmihaserver.properties file in a text editor and repeat
step 2.
5. Restart the PA host agent service.
You can also restore the default port setting to 8331 using the above-mentioned steps.

Start/Stop real-time performance data collection

Prerequisites
• HPE recommends that you dedicate a command device for the real-time performance data collection,
so that it is not used by PA for the regular configuration or performance data collection.
• 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 PA:
Procedure
1. Request a host update.
2. Initiate the configuration data collection from PA, so that the latest configuration data is available for
the XP/XP7 disk array.
3. Configure the real-time database by setting a host agent and a command device for the array.
