[jira] [Created] (SLING-7223) Spikes in RRD after restart

Marcel Reutegger created SLING-7223:
---------------------------------------

             Summary: Spikes in RRD after restart
                 Key: SLING-7223
                 URL: https://issues.apache.org/jira/browse/SLING-7223
             Project: Sling
          Issue Type: Bug
          Components: Commons
    Affects Versions: Commons Metrics RRD4J 1.0.0
            Reporter: Marcel Reutegger


Running the reporter for some time and then restarting the process shows spikes in the collected data. These are caused by counter gauges that are reset to zero after a restart. RRD interprets them as 32bit or 64bit integer overflows and calculates incorrect values.
