Name
pmdbg - translate Performance Co-Pilot debug control flags
Synopsis
pmdbg code ...
pmdbg -l
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.
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.
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(4).
