2. Click the Stop Collections tab.
The Stop Collections table displays the following details for the XP or the P9000 disk arrays, or
a combination of these arrays, for which real-time performance data collection is in progress:
Description Screen elements
The serial number of the XP or the P9000 disk array for which the
real-time performance data collection is in progress.
Array Id
The selected component category. Component Type
The components for which the real-time performance data collection is
in progress.
Components
The host agent through which the real-time performance data collection
is in progress.

3. Select the XP or the P9000 disk array for which you want to stop the real-time performance data
collection.
4. Click Stop Plotting.
The real-time data collection stops and the record removed from the list for the selected XP or
P9000 disk array.
Troubleshooting using host group or WWN
Introduction
P9000 Performance Advisor helps identify bottlenecks in the performance of applications that reside
on hosts and use the XP and the P9000 disk arrays for storing their data. The hosts are identified
using their host groups or WWNs. These hosts might not have P9000 Performance Advisor host
agents installed.
NOTE:
•
In this context, the term 'application' does not include P9000 Performance Advisor. It refers to
applications that reside on hosts and use the XP and P9000 disk arrays to store data. P9000
Performance Advisor helps you identify issues in the performance of such applications.
• If configuration data is collected using the Inband mode for XP and P9000 disk arrays, the applic-
ations can be configured either through WWN or host group name. Similarly, If configuration
data is collected using the Outband mode, the applications can be configured only through the
host group name.
• Applications cannot be associated with components that belong to the XP48 Disk Array, as the
WWNs of the hosts connected to the XP48 Disk Array are not available.
An application's response to user requests is determined by the performance of all the associated
LDEVs, which is attributed to the time taken by the LDEVs to process requests. Higher response time
from the LDEVs leads to increase in response time from the applications to user requests. Further, an
LDEV’s response time is based on components associated with that LDEV.
