Description

we need a nodetool command that outputs columnfamilystore RecentReadLatencyHistogramMicros, RecentReadLatencyHistogramMicros, and (for 0.7) getRecentReadLatencyHistogramMicros.

i'd like this to be in a vertical display with the histogram bucket values from EstimatedHistogram displayed. Like this:

1               0
15              1        
18            542        
22           8091        
79         198290        
114         47248        
850           114        
1020           37
etc
