  The sfarpt utility may be used to analyze SFA files. SFA files are used to hold program profiler measurements.

Usage

usage: sfarpt [options] sfafile [ ... ]
options:
 -f        - file report
 -s        - segment report
 -n        - suppress report header
 -l n      - ignore less than n% execution time    (default = 0%)
 -g n      - ignore greater than n% execution time (default = 100%)
 -b line   - start line number                     (only line report)
 -e line   - end line number                       (only line report)
Default report type is line report.
Files without suffix .SFA are silently ignored if not present.
The options are:
-help
The -help option displays a brief help text.

-f
Output file report.

-s
Output segment report.

-l percent
All lines with elapsed time less than percent are ignored (default = 0%).

-g percent
All lines with elapsed time greater than percent are ignored (default = 100%)

-b line
The analysis begins at line number (line report only).

-e line
The analysis ends at line number. (line report only).

-n
Suppress report header.

Notes

There are three different report types:
  • The file report lists for each program file the execution seconds, the percentage of execution time, the number of lines executed and the percentage of executed lines.

  • The segment report lists for each program segment in the specified program files the percentage of execution time, the number of lines executed and the percentage of executed lines.

  • The line report lists for each program line the percentage of execution time, the number of times the line was executed and and the average execution time.
  • A File extension of .SFA is implied and is appended if not present.
  • Files without suffix .SFA are silently ignored if not present.

Examples

sfarpt -s YSUBR
Create a segment report for YSUBR.
sfarpt -l 0.5 YSUBR
Analyze the YSUBR program file. Any lines whose portion of the elapsed time is less than 0.5% are ignored.
sfarpt -g 0 YSUBR
List all lines which were not executed.
