It's not a bug; carbon was behaving exactly the way it was configured to behave. This wouldn't be surprising to anyone who is familiar with RRDTool. However, since one of the reasons graphite uses its own file format (whisper) instead of RRD is to better handle intermittent values, I could see the argument that the default xFilesFactor should be higher. "xFilesFactor should be a floating point number between 0 and 1, and specifies what fraction of the previous retention level’s slots must have non-null values in order to aggregate to a non-null value. The default is 0.5." - http://graphite.readthedocs.org/en/1.0/config-carbon.html http://graphite.readthedocs.org/en/1.0/config-carbon.html
