Below are common positioning questions asked about HP's
performance products. Some of these questions have been
previously published in the HP PerfRX Information Guide
(RXINFO on the SWT Performance Hotline).
Questions and Answers
=====================
What's the difference between HP PerfRX, HP PerfView,
and HP GlancePlus?
Both HP PerfRX and HP GlancePlus are node-specific
applications geared for analyzing and monitoring a
single system at a time. HP PerfRX provides an in-
depth, historical perspective to global, application,
and process level system activity information. HP
GlancePlus is an on-line diagnostics tool which
provides current system activity information. HP
PerfView is a site level application which provides the
ability to centrally monitor multiple systems in a
distributed computing environment. HP PerfView utilizes
a management-by-exception approach and a sophisticated
alarms technology to provide problem notification and
characterization within the distributed environment.
Is HP PerfView or HP GlancePlus required for HP PerfRX?
No, HP PerfRX is a separate product and does not
require HP PerfView or HP GlancePlus. However, the
features in HP PerfRX, HP GlancePlus, and HP PerfView
complement each other to provide the complete
performance management solution for customers.
How does HP PerfView tie in with HP OpenView Network
Node Manager (NNM) and HP Operations Center?
HP PerfView is a fully integrated application with the
HP OpenView platform. Together HP PerfView, NNM and HP
Operations Center complete an industry leading
distributed management solution. HP PerfView provides
performance and resource management of the nodes on a
network, including resource management alarms and a
graphical Motif interface for detailed analysis of
performance data.
Network Node Manager (NNM) provides system and network
management functions, for instance automatic discovery
of nodes in the distributed computing environment,
tracking of network statistics and utilization levels,
and identifying network problems such as duplicate IP
addresses.
HP Operations Center is designed to provide operations
management and administration. It includes central
system console management, message management, and the
integration point for other system management
applications such as distributed print spooling and
network backup.
Does HP PerfRX collect the performance data?
No, HP PerfRX is an interface to the performance data
collected by the HP Performance Collection Software
(previously known as the HP LaserRX Collection
Software). If a customer does not already own the HP
Performance Collection Software, it can be purchased as
a separate product for UNIX or as part of the HP
GlancePlus Pak bundle.
Can HP PerfRX analyze the data collected by the HP
PerfView Agent?
No. While the HP PerfView Agent and the HP Performance
Collection Software share common technology, HP PerfRX
accesses only the data in the log files created by the
HP Performance Collection Software.
Why is HP Performance Collection Software (PCS)
becoming an industry standard for collecting
performance data on open systems?
Standard facilities within most UNIX based operating
systems provide some performance information. Iostat,
vmstat, and sar are examples. These tools were
designed to help system developers tune the system
kernel, not to help IS staff manage performance and
capacity. PCS reports on all aspects of system
performance including information at three levels:
Global, Application, and process. At each of these
levels, metrics are available on the utilization of
individual resources such as CPU, memory, disk, and
LAN. Information is also available on service levels
such as response times and transaction rates. In all,
over 175 metrics are available.
What's the difference between HP PerfRX and HP LaserRX?
HP LaserRX is a PC-based analysis tool and HP PerfRX
runs on an HP-UX workstation using the Motif user-
interface. While both products fulfill the same
function of long-term data analysis, HP PerfRX does
contain some features not in the LaserRX product. For
example, HP PerfRX can analyze both HP-UX and MPE log
files. It will also be the interface for future
versions of the HP Performance Collection Software on
third party platforms (for example, Sun SPARC systems).
Other features in HP PerfRX include customizable graphs
and an editable script for a command line interface.
