NAME
kgmon - generate a dump of the operating system's profile buffers
SYNOPSIS
/usr/etc/ksmoD (
-b ) ( -h) [
-r ) [
-p ) (
system) ( memory )
DESCRIPTION
Kgmon is a tool used when profiling the operating system. When no arguments are supplied,
kgmon indicates the state of operating system profiling as running, off, or not configured (see
config(8)). If the
-p
flag is specified, kgmon extracts profile data from the operating system and
produces a gmon.out file suitable for later analysis by gproJ{l).
OPTIONS
FILES
-
..
-~
Resume the collection of profile data.
Stop the collection of profile data.
-p
Dump the contents of the profile buffers into a gmon.out file.
-r
Reset all the profile buffers. If the
-p
flag is also specified, the gmon.out file is generated
before the buffers are reset.
If
neither -b nor -h is specified, the state of profiling collection remains unchanged. For exam-
ple, if the
-p
Oag is specified and profile data is being collected, profiling is momentarily
suspended, the operating system profile buffers are dumped, and profiling is immediately resumed.
