[jira] Created: (CASSANDRA-1698) nodetool cfhistograms

nodetool cfhistograms
---------------------

                 Key: CASSANDRA-1698
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-1698
             Project: Cassandra
          Issue Type: New Feature
          Components: Tools
            Reporter: Jonathan Ellis
            Assignee: Pavel Yaskevich
             Fix For: 0.6.7, 0.7.0


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:

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

--------------------------------------------

There is an error in the description of this task - "RecentReadLatencyHistogramMicros, RecentReadLatencyHistogramMicros, and (for 0.7)       getRecentReadLatencyHistogramMicros." - all the same :)

I will do RecentReadLatencyHistogramMicros, RecentWriteLatencyHistogramMicros for 0.6 and can you please specify what will be added for 0.7?

For 0.7, the sstable EHs for row size and column count could be useful too.

-------------------------------------------

i believe what I intended to say was 0.7 should include the sstables-checked histogram.  also brandon's suggestions for row size + column count.

Jonathan Ellis commented on CASSANDRA-1698:
-------------------------------------------

you should follow the pattern in NodeProbe of
{code}
    public JMXInstrumentedCacheMBean getRowCacheMBean(String tableName, String cfName)
{code}

to grab exactly the requested CFSMbean instead of listing all and iterating.

histogram does not show bucket offsets.

tabs are not going to be adequate to align large numbers.
