HP-UX System Administrator's Guide: Overview HP-UX 11i v3 (B3921-90011, September 2010)

HP Caliper The primary purpose of HP Caliper is profiling individual applications,
however Caliper is also capable of displaying overall system performance
information. HP Caliper can be downloaded from: http://www.hp.com/go/

HP Caliper is also supported on versions of Linux for HP Integrity servers.
NOTE: HP Caliper is available only for HP Integrity Servers. For HP 9000
servers, consider using Prospect, a performance monitoring tool. See http://
www.hp.com/go/prospect.
HP GlancePlus GlancePlus is a full featured operating-system-wide performance
monitoring package that provides immediate performance information
about your server. It lets you easily examine system activities, identify and
resolve performance bottlenecks, and tune your system for more efficient
operation. GlancePlus is a part of the HP OpenView Suite of products.
Information about how to obtain GlancePlus and detailed information
about its features is available at: http://www.hp.com/go/openview.
HP GlancePlus supports a variety of operating systems including HP-UX
and Linux.
The following HP-UX commands can also help you gather statistics about how the resources of
your system are being used:
iostat iostat iteratively reports I/O statistics for each active disk on the system.
sar sar, the system activity reporter, samples and reports on cumulative activity counters
in the operating system or from a previously recorded file. These values can give you
a rough idea of where the HP-UX is spending its time.
top Supplied as part of HP-UX, top is a utility that lists all of the processes currently
running on a server, ordered by their processing core usage. Those processes listed
first in the top output are consuming the most processing time. top also shows global
system load factors.
vmstat The vmstat command reports certain statistics kept about process, virtual memory,
trap, and CPU activity. It also can clear the accumulators in the kernel sum structure.
Tools for Monitoring the Performance of a Network
Monitoring the performance of a network can be an involved process involving many different
variables. For sophisticated network troubleshooting and performance monitoring, HP offers
the OpenView Network Node Manager. For information about the Network Node Manager’s
features and capabilities, and how to acquire it see:

If your needs are simply to verify communications between two computers, you can use the
ping command which will send packets from one computer to another and time how long it
takes to receive a reply. You can do some basic tuning of network performance by tweaking
various network settings and running ping to see if the response time improves or worsens. For
