Hi,
I am looking for a way to retrieve some statistic about the usage of the
data on my Cassandra cluster.
Ideally I would like to retrieve a list of the most used token ranges or
partitions over the time through JMX or other similar ways.

I found that nodetool as the option "toppartition" to retrieve the most
used partitions over a sample period. However, it return me this error:

     $ nodetool toppartitions ycsb usertable 100
      nodetool: Argument value's index, calculated according to this
TabularData       instance's tabularType, already refers to a value in this
table.
      See 'nodetool help' or 'nodetool help <command>'.

Am I doing something wrong? Do you know better ways than nodetool?

Thanks in advance
Salvatore
