kgmon - generate a dump of the operating system's profile buffers
/usr/sbin/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 config-
ured. (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.
/vmunix - the default system
/dev/kmem - the default memory
Users with only read permission on /dev/kmem cannot change the state of profiling collec-
tion. They can get a gmon.out file with the warning that the data may be inconsistent if
profiling is in progress.
