-p flag is specified, kgmon extracts profile data from the operating
system and produces a gmon.out file suitable for later analysis by
-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-

file data is being collected, profiling is momentarily suspended, the
operating system profile buffers are dumped, and profiling is immedi-
/vmunix the default system
/dev/kmem the default memory
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.
