HP Capacity Advisor 7.2 User Guide

8 Troubleshooting in Capacity Advisor
Behaviors that you might see when working within the Capacity Advisor user interface that may
not have error or warning messages associated with them are explained in this appendix.
When there is no connection
Within an interdependent solution like Matrix Operating Environment, there are conditions that
can create errors in connection that make it difficult or impossible for some functions to complete
in Capacity Advisor.
Errors in CMS or managed node configuration
Matrix Operating Environment provides a tool called vseassist that you can use to identify and
troubleshoot system configuration errors that may be preventing data collection or other use of
Capacity Advisor. For full information on the vseassist tool, see the HP Matrix Operating
Environment Getting Started Guide.
Internet Explorer times out before report generation completes
In the case where you request a report using data from many managed systems (>100), Microsoft
Internet Explorer may end the session connection before the report is complete. This ends the report
creation; no report is generated for viewing or download.
Suggested action: One way to address this behavior is to create a registry key on your local
Microsoft Windows system to extend the amount of time that Internet Explorer will wait before
closing the connection, as follows:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]
"MaxConnectionsPer1_0Server"=dword:00000005
"MaxConnectionsPerServer"=dword:00000005
"ReceiveTimeout"=dword:5265C0
These settings cause the following to occur:
• MaxConnectionsPer1_0Server and MaxConnectionsPerServer increase the
maximum number of connections that can be used to handle the traffic from the browser.
(Normally, the value is two connections per server; this example shows five connections per
server.)
• ReceiveTimeout extends the timeout boundary of the browser. (Use hexadecimal values
to adjust the time to the desired number of hours, with 24 hours being the maximum time that
will work successfully.)
Other alternatives include:
• Reducing the number of systems included in a single report to <100.
• Running large reports in Mozilla Firefox browser, where this behavior does not seem to occur.
capprofile hangs when exporting non-contiguous data into Capacity Advisor
for profiling
capprofile may hang when exporting large amounts of non-contiguous data (data set containing
significant periods when data was not collected interspersed with periods of data collection).
Suggested action: Export contiguous chunks of data.
Licensing - general
To collect data from a managed node, that node must be licensed to fully use Capacity Advisor
or must have a limited license (the HP Insight Capacity Advisor Consolidation software) for data
