Описание (Description)

If an application needs to know where the Performance Metrics
       Name Space (PMNS) is coming from then pmGetPMNSLocation will
       return whether it is from an archive, PMNS_ARCHIVE, or from a
       local PMNS file, PMNS_LOCAL, or from a remote pmcd, PMNS_REMOTE.

       This information may be useful in determining an appropriate
       error message depending on the PMNS' location.

Диагностика (Diagnostic)

PM_ERR_NOPMNS
              If is not possible to determine where the location of the
              PMNS is.  This could be due to problems with the current
              context or being unable to load a local PMNS.

Окружение PCP (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(5).  Values for these variables may be obtained
       programmatically using the pmGetConfig(3) function.
