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.
