NAME
     kkggmmoonn - generate a dump of the operating system's profile buffers

SYNOPSIS
     kkggmmoonn [-bbhhpprr] [-MM -ccoorree] [-NN -ssyysstteemm]

DESCRIPTION
     KKggmmoonn is a tool used when profiling the operating system.  When no argu-
     ments are supplied, kkggmmoonn indicates the state of operating system profil-
     ing as running, off, or not configured.  (see config(8)) If the -pp flag
     is specified, kkggmmoonn extracts profile data from the operating system and
     produces a gmon.out file suitable for later analysis by gprof(1).

     The options are as follows:

     -bb      Resume the collection of profile data.

     -hh      Stop the collection of profile data.

     -pp      Dump the contents of the profile buffers into a gmon.out file.

     -rr      Reset all the profile buffers.  If the -pp flag is also specified,
             the gmon.out file is generated before the buffers are reset.

     -MM      Extract values associated with the name list from the specified
             core instead of the default ``/dev/kmem''.

     -NN      Extract the name list from the specified system instead of the
             default ``/vmunix''.

     If neither -bb nor -hh is specified, the state of profiling collection
     remains unchanged.  For example, if the -pp 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     /vmunix     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.

HISTORY     The kkggmmoonn command appeared in 4.2BSD.
