-r for Function Coverage Reports
-r [module][:directory][:file][:function][:unknown][none][all]
Default value is module:directory:file:function:unknown.
module Shows data by load module.
directory Groups data by source directory.
file Generates Summary Report by source file.
function Shows function level detail by source file.
unknown When used together with the other report options, provides additional information
about functions from unknown source files in the summary and detail coverage
reports.
-s or --sampling-spec
-s period
-s rate [,variation [,cpu_event
[[:threshold=int][:privilege-level-mask=level]]]]
Specifies the sampling period.
-s period
The -s period version of this option is used only for two measurements:
• cpu
For the cpu measurement, you can use this option in conjunction with the --event-defaults
option to control how samples are taken. For more information, see “Performing CPU Metrics
Analysis ” (p. 151).
• cstack
For more information, see Chapter 11 (page 132).
period Sampling period in seconds or milliseconds or microseconds, measured in CPU cycles
(for cpu) or real time (for cstack). For example:
• -s 1s (1 second)
• -s 100ms (100 milliseconds)
• -s 1000us (1000 microseconds)
For the cpu measurement, the default period is 8 milliseconds. See also
“--cpu-aggregation ” (p. 56).
For the cstack measurement, the default period is 100 milliseconds.
-s rate
The -s rate version of this option is used for all other measurements.
rate Sampling period: specifically, how many sampling events
should occur between samples. The smaller the rate, the
more chance that HP Caliper will affect your program's
performance while collecting information.
variation Sampling period variation: specifically, how much to vary
the number of events between samples. The variation is
the number or percentage of cpu_counter events that HP
Caliper uses to vary the sampling rate. HP Caliper adds or
