respectively. This procedure describes how to create a list of selected (or all) licensed servers and
their data collection periods, and is for use when you want to quickly see the data collection
periods for a set of servers without creating or accessing a scenario to do so.
Prerequisites
• You must have command-line access to the CMS managing the systems of interest.
• The systems of interest must be licensed for Capacity Advisor.
Procedure 5-12 From the command line
• Type
capprofile -lv
to see a list showing the name of each licensed system managed by this CMS, dates for which
data has been collected, and the percent of data considered valid by Capacity Advisor.
For other options, see capprofile in Appendix B (page 129) .
To return to a planning checklist:
•
Obtaining reports on current resource usage [p. 35]
Possible sources of discrepancies in collected data
Several possibilities exist to explain discrepancies that may appear in the data or that may affect
data collection. Check these possibilities to understand what actions you can take to correct the
discrepancy.
No data collected for a managed node
If you do not obtain data on systems from which you expect to collect data, it is possible that the
system has not been licensed for use with Capacity Advisor, either through Insight Dynamics
or through HP Insight Capacity Advisor Consolidation software.
Data timestamp appears to be incorrect
For best accuracy in providing simulation solutions and historic reporting of actual system
resource use, it is assumed that the time clocks of managed nodes are synchronized with the
time clock of the central management server. If, on gathering or collecting data, the date stamp
on your data is not current, the time or time zone on a managed node may be set incorrectly in
relation to the CMS.
Dynamic memory in HP Integrity virtual machines
A dynamic memory feature is available in HP Integrity virtual machines. This allows the memory
allocated to each virtual machine to be changed without rebooting the virtual machine. Capacity
Advisor is aware of this feature and records both the memory allocated to each virtual machine,
as well as how much of this memory is in use for each five-minute interval. Both of these values
are correct when the virtual machines are using the dynamic memory feature.
When a virtual machine is running HP-UX 11.23, most built-in commands such as top and sar
will not be aware of the dynamic memory feature and can show memory sizes that are different
from what is recorded by Capacity Advisor. For example, if a virtual machine is initially booted
with 16 GB of memory, and is then re-sized to 4 GB, the built-in commands will not know about
the change and will show 16 GB for physical RAM. Capacity Advisor, however, will show that
the available memory for the VM is 4 GB. Also, when a virtual machine is sized less than its
maximum size, some built-in commands will show the kernel using more memory than it is
actually using.
Producing graphs and reports
HP Insight Capacity Advisor software can generate both graphical and tabular data for
presentation in either a report format or within an adjustable profile viewer.
