HP Caliper 5.3 User Guide (5900-1558, February 2011)

Specifies whether to extend the callstack samples collection into kernel space. By default, both the
userspace and kernelspace callstack samples will be collected. This option is used only with the
cstack measurement.
--latency-buckets
--latency-buckets True|False
Specifies whether or not the latency bucket information should appear in dcache measurement
reports.
This option is used only with the dcache measurement.
The default value is --latency-buckets True (the information appears).
For more information, see “dcache Measurement Report Description” (page 186).
--measure-on-interrupts
--measure-on-interrupts on|off|only
Controls whether the performance monitoring unit (PMU) is enabled or disabled while processing
interrupts/traps.
This option is used with the measurements that depend on the PMU for their data: alat, branch,
cpu, cycles, dcache, dtlb, ecount, fprof, icache, itlb, pmu_trace, and scgprof.
on The PMU is enabled during interrupt processing, and enabled during regular processing.
off The PMU is disabled during interrupt processing, and enabled during regular processing.
only The PMU is enabled only during interrupt processing, and disabled during regular
processing.
The default is on for the cpu measurement, no matter which --scope option you use.
For all the other measurements, the default is on if you use the --scope system option, and
off if you use the --scope process option.
This option is not available on Linux. The behavior on Linux is equivalent to
--measure-on-interrupts on.
--memory-usage=
--memory-usage=all|[begin][:timed][:end][:PERIOD[s|m|h]]
Controls the collection and reporting of memory usage data.
NOTE: With this HP Caliper option, you must use a qualifier or an equals sign (=). You cannot
use --memory-usage as the option. You must use --memory-usage=.
If you specify --memory-usage=, then --memory-usage=all is assumed.
Use of this option causes two different sets of memory measurements to be taken, each reported
in its own table in the report:
• Overall memory available (and currently in use and free) on the system
• Memory currently being consumed by the process(es) being measured by a particular HP
Caliper run
For details, see “Measuring Memory Usage Concurrently with Other Measurements ” (p. 152).
--metrics
See “-m or --metrics” (p. 49).
