[,variation[,cpu_event[[:threshold=int[:privilege-level-mask=level]]]]
Controls the sampling of the branch trace buffer (BTB)/execution trace buffer (ETB), which produces
the statistical call graph. This option is used only with the scgprof measurement.
The default sampling of the BTB is:
branch_sampling_spec "1000, 5%, BRANCH_EVENT"
The default sampling of the ETB is:
branch_sampling_spec "1000, 5%, ETB_EVENT"
which means that every 1000 BRANCH_EVENT CPU events (on the Integrity servers Itanium 2)
and ETB_EVENT CPU events (on the Integrity servers dual-core Itanium 2 and Itanium 9300
quad-core processors) are sampled, using a 5% variation value.
Use this option to change the default.
rate Specifies how many sampling events should occur between
samples.
The default value is 1,000 events.
variation Specifies how much to vary the number of events between
samples. The number or percentage of CPU_counter events
that HP Caliper uses to vary the sampling rate. HP Caliper
adds or subtracts this number from the interval to vary the
sampling frequency.
The default value is 5 percent.
cpu_event Specifies CPU events to measure. The default value is
BRANCH_EVENT (or ETB_EVENT on the Integrity servers
dual-core Itanium 2 and Itanium 9300 quad-core
processors). Do not change this default value: doing so will
result in a useless call graph.
threshold=int An integer value that specifies how HP Caliper counts events.
The default value is zero. Do not change this default value:
doing so will result in a useless call graph.
privilege-level-mask=level Determines the privilege level setting for a given counter.
By default, counters are measured when your application
