PCTRACK(8)		  BSD System Manager's Manual		    PCTRACK(8)

NAME
     pctrack — print kernel system/interrupt PC sampling history

SYNOPSIS
     pctrack [-fnsi] [-c cpu] [-N execfile] [-M corefile] [interval]

DESCRIPTION
     Kernels compiled with DEBUG_PCTRACK record the program counter (PC) of
     the code interrupted by the statistics clock interrupt.  This information
     can be dumped with the pctrack utility

     The following options are available:

     -c cpu	  Specify which CPU to dump.  If not specified, all CPUs will
		  be dumped.

     -f		  If a single CPU and either -i or -s is specified, this
		  option will use the repeat interval to detect changes and
		  dump them as they occur.

     -i		  Dump the interrupt tracking buffer.

     -s		  Dump the kernel tracking buffer.  If neither -i or -s is
		  specified, both tracking buffers will be dumped.

     -n		  pctrack normally tries to translate the PC into symbols.
		  This option forces hex values to be displayed instead.

     -N 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.

HISTORY
     The pctrack utility first appeared in DragonFly 1.5.

AUTHORS
     The pctrack utility was originally implemented by Matthew Dillon for
     DragonFly.
