KGMON 8 ""
C 5 NAME
kgmon - generate a dump of the operating system's profile buffers
SYNOPSIS
/etc/kgmon [
-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
gprof (1). The following options may be specified:
-b Resume the collection of profile data.
-h 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 example, if the -p flag is specified and profile data is being collected, profiling will be momentarily suspended, the operating system profile buffers will be dumped, and profiling will be immediately resumed.
FILES
/vmunix - the default system
/dev/kmem - the default memory
"SEE ALSO"
gprof(1),
config(8)
DIAGNOSTICS
Users with only read permission on /dev/kmem cannot change the state
of profiling collection.
They can get a
gmon.out file with the warning that the data may be
inconsistent if profiling is in progress.
