HP Caliper User's Guide

$ cat /path/ls.sh

#!/bin/sh

$ caliper ecount -p "(arg1)*ls.sh" /path/ls.sh

Reports information for: /bin/sh /path/ls.sh, but does not report ls.

• To select based on argv0:

$ caliper ecount -p "(arg0)ora*" ./sqlplus

Reports information on processes having ora as a prefix of their argument 0.

• To detach from unimportant processes:

$ caliper ecount -p "*" -p (ignore)basename ...

HP Caliper does not track or measure children of the detached process.

Using HP Caliper in Your Build Process

You can integrate HP Caliper into your build process by including the HP Caliper

commands in your makefile.

Using HP Caliper in Testing and Quality Assurance

Use these steps with new makefile targets for testing and quality assurance builds:

1. Make predefined HP Caliper performance measurements using your sample data

sets.

2. Compare HP Caliper results with results from previous builds to identify

performance improvements or regressions.

Using HP Caliper to Generate Test Suite Reports

To automatically generate HP Caliper reports during your builds on HP-UX (for

example, in test suites), use entries in your makefile such as these:

# Makefile rule for generating some common performance reports.

performance_reports: main_program

/opt/caliper/bin/caliper ecount -o main_program.ecount main_program

/opt/caliper/bin/caliper fprof -o main_program.fprof main_program

Attaching to a Running Process to Perform Measurements

HP Caliper offers the ability to attach to one or more running process to perform

measurements. This feature can be particularly useful to measure daemon processes.

For sampled measurements you can attach to a running process and detach from the

process after a specified duration for these measurements:

• alat

• branch

• cpu
