NAME

   pmdbg - translate Performance Co-Pilot debug control flags

SYNOPSIS

   pmdbg code ...
   pmdbg -l
   pmdbg -D name[,name ...]

DESCRIPTION

   The components of the Performance Co-Pilot (PCP) use a global vector of
   bit-fields to control diagnostic and debug output.

   pmdbg with a -l argument prints out the mnemonic and decimal values  of
   all the bit-fields in the debug control vector.

   pmdbg   with   a   -D  argument  parses  the  list  of  names(s)  using
   __pmParseDebug(3) and reports the corresponding decimal value.  This is
   most useful when debugging and wanting to set the internal value of the
   control vector (pmDebug) via a debugger, e.g.  gdb(1).

   In the alternative usage, the code arguments are values for  the  debug
   vector,  and the bit-fields that are enabled by each of these values is
   listed.

   Each code may be an integer, a hexadecimal value or a hexadecimal value
   prefixed by either ``0x'' or ``0X''.

   Most  applications  using  the  facilities  of  the  PCP  support a -DN
   command-line syntax to enable debug control.  pmdbg is designed to help
   choose an appropriate value for N.

   Alternatively  the  initial value of the debug control flags may be set
   to a value N  using  the  environment  variable  $PCP_DEBUG.   If  both
   mechanisms  are used the effect is additive, so the resultant flags are
   those set via $PCP_DEBUG combined with those set  via  any  -D  command
   line options.

PCP ENVIRONMENT

   Environment variables with the prefix PCP_ are used to parameterize the
   file and directory names used by PCP.  On each installation,  the  file
   /etc/pcp.conf  contains  the  local  values  for  these variables.  The
   $PCP_CONF variable may be used to specify an alternative  configuration
   file, as described in pcp.conf(5).
