• scgprof
The scgprof measurement measures and reports (an inexact) call graph profile,
produced by sampling the PMU to determine function calls. See “Producing a
Sampled Call Graph Profile Analysis” (p. 157) and “scgprof Measurement Report
Description” (page 288).
• traps
The traps measurement collects and reports a profile of traps, interrupts, and
faults. See “traps Measurement Report Description ” (page 292).
These measurement configuration files are grouped into three categories based on the
primary type of measurement, as shown in Table 4-1 “Available Measurements in Each
Measurement Type”.

NOTE: The cgprof measurement performs both sampled and precise measurements.
The measurements in the sampled category, with the exception of cpu and pmu_trace,
show results grouped by function. A report produced by any of these measurements
is referred to as a PMU histogram report.
The measurements in the precise category use dynamic instrumentation to perform
their measurements.
Overview Measurement
The overview measurement enables collecting fprof, dcache, and cstack data in
one single collection run. To run overview on an application enter:
