pmdbg - Man Page

pmdbg [-l]

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

pmdbg prints out all the available debug options with the name of the option and some descriptive text.

The -l option does nothing, but is included for backwards compatibility with older versions of pmdbg.

Most applications using the facilities of the PCP support a -D name[,name ...] command-line syntax to enable debug control using the name(s) of the desired debug options.

Alternatively the initial value of the debug control flags may be set to a comma-separated list if option name(s)  using the environment variable $PCP_DEBUG, provided the applications use pmGetOptions(3) to process command line options and arguments. 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).

Prior to PCP 7.0 debug options were maintained in a dual state with an old-style binary encoded integer (plus macro name for programmers), and a new-style character string name for each debug option.

In PCP 7.0 support for the the old-style was dropped.

The table below documents the equivalence for those debugging options that appeared in both the the old and the new styles.
