kgmon - generate a dump of the operating system's profile buffers
/etc/kgmon [ -b ] [ -h ] [ -r ] [ -p ] [ system ] [ memory ]
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
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 speci-
fied, the gmon.out file is generated before the buffers are
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.
/vmunix - the default system
/dev/kmem - the default memory
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.
