In addition, as a general rule, Riak's data disk should never get more than about 80% full (assuming it holds only Riak data), as additional disk space may be needed when fallback partitions are created when another node is down. Rather than looking at point in time values as reported by `riak-admin status` and the HTTP `stats` endpoint, it is often more valuable to graph the development of the reported statistics over time. Of particular interest are the GET and PUT times reported (both node and vnode), as these will show the latencies of the cluster when returning results.
