            Bug ID: 1378184
           Summary: pcp pmdas/metrics that don't support container
                    inspection should be blocked rather than returning
                    host results
           Product: Fedora
           Version: rawhide
         Component: pcp

Container support across the PMDAs, and even within some PMDAs, is
inconsistent.  When a user tries 

% pminfo -f -h 'pcp://....?container=HEXCODE'

one gets a mishmash of host and container data, with no indication about which
is which.  We should audit the PCP PMDA codebase, and identify PMDAs/metrics
that disregard a requested container spec.  They should return "no values" or
something like that instead of a bad value.
