    PR #5 (itself based on #4) introduced support to scrape the "global" scope,
    however the format of these stats differs slightly from that of the
    As a result of this, combined with the silent return when `len(values)
    != len(columns)+1`, these metrics were being incorrectly exported as
    mislabeled metrics with values of 0.
    The changes in this PR accomodate for the format of the "global" scope
    and now properly scrape those as well.
    It will now also display an error when column counts mismatch, reducing
    the likelihood of silent errors in the future.
    Global metrics will now show up as:
