Issue

  • Since upgrading the pcp package, pcp utilities such as pminfo or pmlogextract fail with the following error

    # pminfo -a <path/to/archives>
pminfo: Cannot open archive "<path/to/archives>": The semantics of a metric has changed in an archive

# pmlogextract <path/to/archives> /tmp/out
pmlogextract: Error: cannot open archive "<path/to/archives>": The semantics of a metric has changed in an archive

  • Opening individual archives is possible

    # pminfo -a <path/to/archives>/20171202 | wc -l
374
