KGMON(8) KGMON(8) NAME kgmon - generate a dump of the operating system’s profile buffers SYNOPSIS /etc/kgmon [ -b ] [ -h ] [ -r ] [ -p ] [ system ] [ 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). 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 speci‐ fied, 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 pro‐ file 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 SEE ALSO gprof(1), config(8) 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. 4.2 Berkeley Distribution April 27, 1985 KGMON(8)
