HP Caliper User's Guide

7 Using the HP Caliper Advisor in the GUI
This chapter describes how to use the HP Caliper Advisor in the HP Caliper graphical
user interface (GUI). It assumes that you have some familiarity with the Advisor.
For information about the HP Caliper Advisor, see Chapter 6 (page 101).
For information about the HP Caliper graphical user interface (GUI), see Chapter 3
(page 43).
Basic Steps in Using the HP Caliper Advisor in the GUI
Using the Advisor in the GUI is similar to using it by means of the command-line
interface, but easier. The basic steps are:
1. Make one or more HP Caliper performance measurement runs in the GUI, or
import previously collected data.
2. [Optionally] select the performance data that you want analyzed.
3. Click on the Generate Advice button or menu choice.
4. Review and follow the advice given in the Advisor report.
This advice might suggest additional measurement runs to gather more performance
data for further analysis. If so, simply repeat steps 1 through 4.
Making Performance Measurement Runs
The Advisor has a wide range of analysis rules that cover the different measurements
that HP Caliper can make. You might already have an idea of the type of performance
problem you have and might have already made some measurement runs. Start with
that data.
If you do not know where to start, the following measurements are good to make:
Sampled call graph (the default measurement)
CPU metrics (HP-UX only)
CPU cycles (flat profile) (Integrity servers dual-core Itanium 2 and Itanium 9300
quad-core processor systems only)
The more performance data the Advisor has available to analyze, the better the advice
it can give. However, you can start using the Advisor with as little as one set of
measurement data. This data will guide you in additional measurements to make.
