KGMON(8)

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

SYNOPSIS
/usr/etc/kgmon [ -bhpr ] [ filesystem ] [ memory ]

DESCRIPTION
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 gprof(1).

OPTIONS

-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 is momentarily suspended, the operating system profile buffers are dumped, and profiling is immediately resumed.

FILES
/vmunix
    the default system
/dev/kmem
    the default memory
gmon.out

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.
