Table 15 Information in cgprof Measurement Report: Children Listings
DescriptionColumn
Number of hits due to this child entry and its descendants, expressed as a percentage
of the number of hits accounted for by the self entry and its descendants.
% Func Hits In Children
Number of times the function represented by the self entry was called by this child.Called*
Number of times this child is called by all functions./Total**
Fraction of Called/Total expressed as a percentage. This represents the percentage of
times the self entry called this child entry as compared to the total number of calls for
this child entry.
% Call Total
Name of this child function.Children
Cycle that this child is a member of, if any.Cycle
The cycle as a whole is listed with the same fields as a function entry. Beneath it are
listed the members of the cycle, and their contributions to the time and call counts of the
cycle. Above it are listed the non-member functions that called the different members of
this cycle, the number of hits propagated to every one of these callers and the call counts
for every one of these callers from outside the cycle.
*This field is omitted for parents, or children, in the same cycle as the function. If the function, or
child, is a member of a cycle, the propagated times and propagation denominator represent the
self time and descendant time of the cycle as a whole.
**Static-only parents and children are indicated by a call count of 0.
cpu Measurement Report Description
Available only on HP-UX.
With the cpu measurement, produced by the cpu measurement configuration file, HP Caliper
measures and reports per-process or system-wide metrics based on sampled CPU events.
Specify the events and sampling period with the -m event_set and -s period options,
respectively. You can measure multiple metrics in the same run.
The --cpu-aggregation option specifies how many low-level samples will be aggregated into
one user-reported sample.
The default value used with the cpu measurement is overview.
The report shows this information:
• Summary statistics for all of the samples in the measured application:
MEAN — Mean value of all samples.◦
◦ STDEV — Standard deviation of the samples.
◦ 90%CI — 90 percentage confidence interval. This indicates that, statistically, 90% of the
time, the mean value will lie within this distance from the present mean value.
◦ MINIMUM — Minimum value across all samples.
◦ LOW90 — Lowest value in the 90% confidence interval. This indicates that, statistically,
90% of the time, the mean value will be higher than or equal to this value.
◦ HIGH90 — Highest value in the 90% confidence interval. This indicates that, statistically,
90% of the time, the mean value will be lower than or equal to this value.
◦ MAXIMUM — Maximum value across all samples.
