PMDBG(1)                   General Commands Manual                  PMDBG(1)

NAME         top

       pmdbg - translate Performance Co-Pilot debug control flags

SYNOPSIS         top

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

DESCRIPTION         top

       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         top

       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).
