pmdbg - translate Performance Co-Pilot debug control flags
pmdbg code ... pmdbg -l pmdbg -D name[,name ...]
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.
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).
