HP Integrity Essentials Capacity Advisor is a
tool in the HP Virtual Server Environment Management (VSEMgr) suite
designed for doing capacity planning by simulating placement of application
workloads to help IT administrators improve server utilization.
Capacity Advisor captures server utilization data
and manages what-if configuration scenarios to perform ongoing capacity
planning. One source for server utilization data is HP OpenView Performance
Agent (OPVA). OVPA data can be imported into the Capacity Advisor
database using the capovpaextract(1M) command.
Before the Capacity Advisor Version A.03.00.00
release, capovpaextract could import data only from nodes listed in
VSEMgr, that is, nodes running HP-UX 11i or the Integrity versions
of Microsoft®™ Windows®™ and Linux. With the 3.0 release, capovpaextract can now import
data from a wider variety of systems including systems running HP-UX
11.0 and 10.20, systems running Solaris, and x86 systems running Linux.
This white paper describes a process for importing
OVPA data into Capacity Advisor from nodes not listed in VSEMgr. This
is useful when collecting data from:
Systems where administrators do not want to expose
the root password, required for capovpaextract execution
Systems without a ssh (secure shell) connection, usually
running behind firewalls
Any data source where the user can acquire utilization
data manually
To use data from nodes not listed in VSEMgr and
Capacity Advisor, the user must:
Import OVPA data into
Capacity Advisor as a non-VSE workload[1]. This task is described in Section 2 and an example is
shown in Section 3.
Import this non-VSE workload
into a scenario, because non-VSE workloads can be used only in Capacity
Advisor scenarios. This second task is described in Section 4.
Section 5 lists the operating systems supported
for these tasks, while later sections provide References and a Glossary.
