SYNOPSIS
     ktrdump [-cfqrtH] [-i ktrfile] [-M core] [-N system] [-o outfile]

DESCRIPTION
     The ktrdump utility is used to dump the contents of the kernel ktr trace
     buffer.

     The following options are available:

     -c 	 Print the CPU number that each entry was logged from.

     -f 	 Print the file and line number that each entry was logged
		 from.

     -q 	 Quiet mode; do not print the column header.

     -r 	 Print relative timestamps rather than absolute timestamps.

     -t 	 Print the timestamp for each entry.

     -H 	 Print the thread ID for each entry.

     -i ktrfile  File containing saved ktr trace events; for more information
		 see the ktr(4) manual page.

     -N system	 The kernel image to resolve symbols from.  The default is the
		 value returned via getbootfile(3).

     -M core	 The core file or memory image to read from.  The default is
		 /dev/mem.
