KTRDUMP(8)              FreeBSD System Manager's Manual             KTRDUMP(8)

NAME
     ktrdump - print kernel ktr trace buffer

SYNOPSIS
     ktrdump [-cfqrt] [-e execfile] [-i ktrfile] [-m corefile] [-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.

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

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

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

     -o outfile         The file to write the output to.  The default is
                        standard output.
