For those of you using radsniff for stats collection, has anyone had any
luck using the telgraf collectd plugin? radsniff seems to work fine to
collectd but when I plumb it to telegraf, telegraf complains about invalid
packet length. I have a bug open for telegraf, but I was wondering if
anyone else has the same issue.
