--------------------------------------------------
Monitoring the status of streaming on both source and destination nodes can be found (in 0.6) under the `org.apache.cassandra.streaming.StreamingService` MBean. The `Status` attribute gives an easy indication of what a node is doing with respect to streaming.
- Step 2 is what takes the most time on most systems. The destination will be idle during this stage; to monitor anti-compaction progress, you should check the `Compaction` mbean on the source.
+ 一連の処理の中でステップ2が最も時間を要します。この作業が行われている間、データ受信側はデータ受信のみしか出来なく成ってしいます。Anti-Compactionの監視を行うのであれば、Data送信NodeのCompaction MBeanを覗くと良いでしょう。

Once step 3 begins actual data transfer, the sending node will report a status of `"Waiting for transfer to $some_node to complete."` The receiving node will report `"Receiving stream"` while receiving stream data. The `StreamDestinations` and `StreamSources` attributes each contain a list of hosts that the current node is either sending stream data to or receiving it from.
