-m or --metrics

This option has two forms: -m cpu_event and -m event_set

-m cpu_event

This form is used to specify one or more CPU events to measure:

-m cpu_event[[:threshold=int][:privilege-level-mask=level]][,cpu_event[:...]]

You can change the default CPU events recorded for any of the following measurements:

• alat

• branch

• cycles

• dcache

• dtlb

• ecount

• fprof

• icache

• itlb

• pmu_trace

If you use this option but do not specify an event, or if the option value is set to the

empty string (""), then no metrics will be reported.

You can use the caliper info command to list available CPU events and their

descriptions.

cpu_event

Specifies a CPU event to measure. The name is

not case-sensitive. For information about CPU

events you can specify, see “Specifying Which

CPU Events to Measure” (p. 123).
