PARAMETERS

	      o $flags
		-  Optional  flags  to	add  additional information to the profiling. See the XHprof constants for further information about these
		flags, e.g., XHPROF_FLAGS_MEMORY to enable memory profiling.

	      o $options

Name
       kgmon - generate a dump of the operating system's profile buffers

Syntax
       /etc/kgmon [ options ] [ system ] [ memory ]

Description
       The command is used when profiling the operating system.  When no arguments are supplied, indicates the state of operating system profiling
       as running, off, or not configured.  For further information, see If the option is specified, extracts profile data from the operating sys-
       tem and produces a file suitable for later analysis by

       The  file  is first converted to a format suitable for by using the filter. The command dumps the kernel profiling data for all the proces-
       sors in the system. The command is used to create a file suitable for analysis by for any or all the processors in the system.

Options
       -b   Resumes the collection of profile data.

       -h   Stops the collection of profile data.

       -p   Dumps the contents of the profile buffers into a file.

       -r   Resets all the profile buffers.  If the option is also specified, the file is generated before the buffers are reset.

       If neither nor is specified, the state of profiling collection remains unchanged.  For example, if the option 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.

Diagnostics
       Users with only read permission on cannot change the state of profiling collection.  They can get a file with the warning that the data may
       be inconsistent if profiling is in progress.

Files
       Default system

       Default memory
