title: How do I make Dask Dashboard working properly?
body: <p>I used AWS EC2 to run everything, in one Jupiter notebook process, I do:</p>
  <pre><code>from dask.distributed import Client, LocalCluster
  cluster = LocalCluster(scheduler_port=5272, dashboard_address=5273,memory_limit='4GB')
  # client = Client(cluster)
  </code></pre>
  <p>to start a client specifying a port. Then in another process, I join it with,</p>
  <p><code>client = Client('tcp://127.0.0.1:5272') </code>
  To check the dash board, I open with safari</p>
  <p><code>http://ec2-1-123-12-123.compute-1.amazonaws.com:5273/status </code></p>
  <p>I could see the dash board, but when i run some big processing tasks, there is no action in the dashboard. still showing little cpu usage. But I saw, huge cpu usage in <code>htop</code> , with my <code>ddf.compute()</code> running... Did I miss anything?</p>
