KGMON(8) System Manager's Manual KGMON(8)NAME
kgmon - generate a dump of the operating system's profile buffers
SYNOPSIS
/usr/sbin/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 pro-
file 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 warn-
ing that the data may be inconsistent if profiling is in progress.

SYNOPSIS
kgmon [-bdhpr] [-M core] [-N system]
DESCRIPTION
kgmon is a tool used when profiling the operating system. When no arguments are supplied, kgmon indicates the state of operating system pro-
filing as running, off, or not configured (see config(1)). If the -p flag is specified, kgmon extracts profile data from the operating sys-
tem and produces a gmon.out file suitable for later analysis by gprof(1).
The options are as follows:
-b Resume the collection of profile data.
-d Enable debug output.
-h Stop the collection of profile data.
-M core
Extract values associated with the name list from the specified core instead of the default /dev/kmem.
-N system
Extract the name list from the specified system instead of the default /netbsd.
-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
/netbsd the default system
/dev/kmem the default memory
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.
