[pcp:master] New Comment on Issue #275 RFE: pminfo option to indicate which metrics are actually available (an inverse of -v option) ( https://github.com/performancecopilot/pcp/issues/275 )

William, this is simple enough ... except for the "No values" metrics ... these are currently reported with -v.

These are metrics that might never have a value on a particular machine (e.g. tape.dev on a machine with no scsi tape units) or might have a value at some time in the future (e.g. the hotptroc metrics).

Should these metrics be included with the new option (so skip metrics that return errors only), or excluded with the new option (so only include metrics with at least one value)?
