If I look at Read Latency I see indeed that they are reset during two runs of cfhistograms. However, "Row Size" and "Column Count" keep the values. When are they re-evaluated?

Quick question.

I am using Cassandra 1.0.11

When is nodetool cfhistograms output reset? I know that data is collected during read requests. But I am wondering if it is data since the beginning (start of Cassandra) or if it is reset periodically?

It is reset on node restart and on each call to nodetool cfhistograms.
