HP Caliper User's Guide

The default depth is 32.
--group-by
--group-by executable | module | none
Specifies how “matching” processes or modules should have their data combined in
reports. (Matching processes or modules are processes or modules that have the same
basename.)
This option can be used anytime you use the caliper command to produce a report
(including the default stdout report). It can also be used when you use the following
commands to create a report from one or more databases: caliper report, caliper
merge, and caliper diff.
executable
Specifies that “matching” processes should have their data combined
when possible.
This is the default for all HP Caliper reports and for all caliper
report, caliper merge, and caliper diff commands.
module
Specifies that “matching” modules should have their data combined.
This produces a module-centric report. In a module-centric report,
there is no data about individual processes in the collection runs.
Instead, all matching modules with data that can be merged are
grouped together, across processes.
The following HP Caliper measurements cannot be combined across
processes or modules:
• cgprof(HP-UX only)
• cpu(HP-UX only)
• pmu_trace
• scgprof
Collections with the above measurements will always be processed
as if --group-by none were specified.
See “Module-Centric Reports” (page 140).
none
Specifies that data from matching processes or modules should not
have their data combined. This is used only for the caliper and
caliper report commands.
See “Creating Reports from Multiple Databases” (page 149).
--help
See “-H or --help” (p. 66).
