KGMON(8) BSD System Manager's Manual KGMON(8)
NAME
kgmon -- generate a dump of the operating system's profile buffers
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.
SEE ALSO
config(1), gprof(1)
HISTORY
The kgmon command appeared in 4.2BSD.
BSD
June 6, 1993 BSD
