Sampled Call Graph Profile Report Details
This section gives some information about the Sampled Call Graph Profile report. For more
information, see “scgprof Measurement Report Description” (p. 211).
Flat Profile Part of the Report
The flat profile part of the report contains two levels of information:
• Function Summary: exact counts of CPU metrics summed across an entire run of a measured
application
• Function Details: sampled IPs that are associated with particular locations in the measured
application
You can specify how to arrange the results in the flat profile with the --sort-by option. The valid
sorting parameters are:
• call-count
• msecs-per-call
• samples (default)
• seconds
See “Metrics You Can Use for Report Sorting and Cutoffs” (p. 105) for details.
Call Graph Part of the Report
The lines full of dashes divide the call graph into entries, one for each function. Each entry has
one or more lines.
In each entry, the primary line is the one that starts with an index number in square brackets. The
end of this line says which function the entry is for.
The preceding lines in the entry describe the callers of this function.
The lines following the primary line describe its subroutines (called children in the call graph). The
entries are sorted by time spent in the function and its subroutines.
Hot Call Paths Part of the Report
This section reports the most probable hottest call paths. A call path represents a subset of the
program's execution. The Hot Call Paths section reports the percentage of a program's CPU time
that is attributed to specific call paths. Since scgprof does not store the whole call stack, it only
tries to report the most probable hot paths in the program. There could be some false positives
and false negatives as well in the report.
You can use the --callpath-cutoff option to specify cutoff values that limit the hot callpaths
reported in this section. See “--callpath-cutoff ” (page 55)“ .
Function Indexes
The Function Indexes, which follows the Call Graph, is an alphabetical list of each function in your
program with its index value.
