-p

For simple uses:

[some:][(opt1,...)]pattern

-p glob1[:glob2:...]

 

Matches the executable base name of each new process

 

against each glob pattern. A glob pattern follows the Unix

 

shell-style rules to expand file names. If one or more of those

 

patterns match, the process is measured. Otherwise the

 

process is tracked.

 

For more information, see “Using -p some ” (p. 98).

If you specify multiple -poptions, the last one takes precedence.

Using -p some

The syntax for -p some is the most complex.

-p [some:][(opt1[,opt2,...])]pattern

where:

opt1, opt2 represent the options from the following tables that either specify the action to take or a condition the process must meet

pattern represents the string that HP Caliper uses to compare with options that require a pattern

When you specify multiple some: arguments for process, the result of each some: argument is

passed the subsequent some: argument, typically reducing the number of matching results.

The (opt1[,opt2,...]) are optional and only required to change the default behavior. The absence of options is equivalent to providing the options (measure, file).

Options can be grouped in categories, as shown in the tables below.

Table 3 Action Options Used with -p some

Option

Description

 

 

measure

Default. Measures the process.

 

 

track

The process is not measured. However, HP Caliper learns about events in this process, in particular,

 

creation of new processes via fork, vfork, and exec.

 

 

ignore

The process is not measured. HP Caliper does not track events for this process or any child the

 

process may create.

 

 

The last option specified takes precedence.

Table 4 Pattern String Interpretation Options Used with -p some

Option

Description

 

 

glob

Default. Interprets the string as a “:”-separated list of glob patterns.

 

 

regexp

HP Caliper interprets the string as a single Python or Perl type regular expression that is used

 

with search.

 

 

The last option specified takes precedence.

Table 5 Name Source Options Used with -p some

Option

Description

 

 

file

Default. The name is the executable base name of the process.

 

 

arg0 or argv0

The name is argument 0 of the process.
