<h1 class="topictitle1">Collecting performance data across partitions</h1>
<div><p>IBM<sup>®</sup> Performance
Management for <img src="eserver.gif" alt="eServer" /> <span class="keyword">iSeries™</span> (PM eServer™ <span class="keyword">iSeries</span>) automatically triggers Collection
Services to gather nonproprietary performance and capacity data from your
server and then sends the data to IBM for analysis.</p>
<div class="section"><p>One of the analyses PM <span class="keyword">iSeries</span> provides
is to plot the growth of the system to determine when an upgrade may be necessary.
For a system that is not partitioned, this is a straightforward process. However,
if your system has been partitioned into multiple <span class="keyword">i5/OS™</span> partitions,
the data arrives at IBM from each partition separately, which makes forming
a reliable view of the entire system performance more difficult. If the partitions
are running AIX<sup>®</sup> or Linux<sup>®</sup>,
or if any of the <span class="keyword">i5/OS</span> partitions
have PM <span class="keyword">iSeries</span> turned off,
then no data is sent, which makes forming a view of the entire system nearly
impossible.</p>
<p>To address these problems, Collection Services, with <span class="keyword">IBM Director</span> Multiplatform, can now retrieve
data about CPU usage and number of processors available from your server partitions
regardless of the operating system running on them. PM <span class="keyword">iSeries</span> summarizes
the data before it gets shipped to IBM. Providing a cross-partition view of
CPU utilization helps you and IBM do a much better job of managing your
system resources. This includes balancing workload across the current set
of processors as well as being able to plan for the purchase of more or faster
processors when necessary.</p>
<p><strong>How does it work?</strong></p>
<p>The graphic
below illustrates how the collection of CPU utilization data across logical
partitions works. The "central system" has the <span class="keyword">IBM Director</span> Server
installed on an <span class="keyword">i5/OS</span> partition
that is running Collection Services with the *LPAR category selected. Each
of the other partitions must have the <span class="keyword">IBM Director Agent</span> installed
and configured so that <span class="keyword">IBM Director</span> Server
can collect performance data from them. Each partition must also have the
Director Multiplatform extension for Collection Services installed. <span class="keyword">IBM Director</span> Server retrieves the CPU
utilization data for each partition, including itself, at regular intervals
and stores that data in the Collection Services *MGTCOL object. The data is
then processed and written to the QAPMLPAR database file. Finally, PM <span class="keyword">iSeries</span> collects and aggregates the
data and prepares to transmit it to IBM. Although this graphic shows Management
Central and IBM Electronic
Service Agent™ (ESA) set up to transmit data on the same partition as
the <span class="keyword">IBM Director</span> Server and Collection
Services, the transmission mechanism to IBM could actually be running on a completely
different system and still be set up to gather the cross-partition data from
PM <span class="keyword">iSeries</span> and send it to IBM,
business as usual.</p>

<p>The following list provides you with an
overview of the steps you must complete to collect performance data across
logical partitions:</p>
</div>
<ol><li class="stepexpand"><span>Ensure your IP network is properly configured for all partitions
on the same physical system.</span></li>
<li class="stepexpand"><span>Ensure you are running a supported operating system on each partition
for which you want to collect performance data:</span> <ul><li><span class="keyword">i5/OS</span>, Version 5 Release
4</li>
<li>AIX
5L™, version 5.3</li>
<li>Red Hat Enterprise Linux AS, version 3.0, for IBM PowerPC<sup>®</sup></li>
<li>SUSE LINUX Enterprise Server 8 for IBM pSeries<sup>®</sup> and IBM <span class="keyword">iSeries</span></li>
<li>SUSE LINUX Enterprise Server 9 for IBM pSeries and IBM <span class="keyword">iSeries</span></li>
</ul>
</li>
<li class="stepexpand"><span>Ensure that you have applied the following Collection Services
fixes to the partition that acts as your management server:</span> <ul><li>SI12971</li>
<li>SI13838 (superseded by SI16328)</li>
<li>SI15131 (superseded by SI16499)</li>

</li>
<li class="stepexpand"><span>Use the Virtualization Engine™ to install <span class="keyword">IBM Director</span> Server on the <span class="keyword">i5/OS</span> partition
that you want to act as the management server. Consider the management server
the central control point that communicates to managed systems, devices, and
Collection Services. When the Virtualization Engine installation
wizard is complete, <span class="keyword">IBM Director</span> Server
and <span class="keyword">IBM Director Agent</span> are installed
on the <span class="keyword">i5/OS</span> partition
that you want to act as the management server.</span></li>
<li class="stepexpand"><span>Install <span class="keyword">IBM Director Agent</span> on
the partitions that you want to be managed by <span class="keyword">IBM Director</span> Server.
These partitions must be on the same physical system as the partition where <span class="keyword">IBM Director</span> Server is installed.</span></li>
<li class="stepexpand"><span>Install <span class="keyword">IBM Director</span> Console
