NAMESPACE ERRORS

These errors may occur in the processing of PCP namespace
       operations.  A PCP namespace, see PMNS(5), provides the external
       names and the internal identifiers for the available performance
       metrics.

       PM_ERR_NONLEAF
              Metric name is not a leaf in PMNS
              The metric name passed to pmLookupName(3) names a non-
              terminal path in the namespace, i.e. a group of metrics
              rather than a single metric.

       PM_ERR_DUPPMNS
              Attempt to reload the PMNS
              When using an explicit local namespace, it is illegal to
              call either of pmLoadNameSpace(3) or
              pmLoadASCIINameSpace(3) more than once.

       PM_ERR_PMNS
              Problems parsing PMNS definitions
              Only occurs when an ASCII namespace is explicitly loaded.

       PM_ERR_NOPMNS
              PMNS not accessible
              Only occurs when an ASCII namespace is explicitly loaded.
