Subject [jira] [Updated] (CASSANDRA-7375) nodetool units wrong for streamthroughput
Date Tue, 10 Jun 2014 18:05:01 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-7375?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mike Heffner updated CASSANDRA-7375:
------------------------------------

    Description: 
Stream throughput is measured in megabits (Mbps) in cassandray.yaml:

{code}
# When unset, the default is 200 Mbps or 25 MB/s.
# stream_throughput_outbound_megabits_per_sec: 200
{code}

However, the nodetool command uses the unit "MB/s" which implies megabytes/sec:

  getstreamthroughput    - Print the MB/s throughput cap for streaming in the system
  setstreamthroughput  <value_in_mb> - Set the MB/s throughput cap for streaming in
the system, or 0 to disable throttling.

$ nodetool getstreamthroughput
Current stream throughput: 200 MB/s

Fix references in nodetool to use Mbps
