How to view Dask dashboard when running on a virtual machine?

Here is what I'm doing now:

Printing client shows that the dashboard is located at http://127.0.0.1:8787/status, however, I cannot find the dashboard at that URL. I've also tried http://11.11.11.111:8787/status but that didn't work either.

I'm still able to run everything in my notebook with Dask Dataframes just fine, but I just can't figure out how to view the dashboard. Bokeh is installed on server and I'm running Jupyter Notebook through Anaconda.

Finally figured it out with some SSH Tunneling.

More background on problem:

  • Local machine is a Windows laptop
  • Remote server is a CentOS box

The goal is actually two-fold:

  1. Run Jupyter Notebook on remote server that contains Dask code

  2. View Dask Dashboard from code running in Notebook

Here are the steps I took:

  1. For this example, IP Address of remote server is 11.11.11.111

  2. Following some instructions for Port Tunneling, I use 8001 as the Source Port and Destination is localhost:8889

  3. After connecting to the remote server (which has 16 cores and 44.7GB of RAM), I ran this in Putty terminal: dask-worker tcp://11.11.11.111:8786 --memory-limit=auto --nthreads=1 --nprocs=16 &

  4. Start Jupyter Notebook on server: jupyter notebook --ip=0.0.0.0 --port=8889 --no-browser &

    a. After running above command, output shows that Jupyter notebook is running at http://(hostname or 127.0.0.1):8889/?token=blahblahblah

    b. Opening a browser and going to the URL above (http://hostname:8889/?token=blahblahblah) brings to Jupyter Notebook home page

  5. Create new Notebook and run following code:

    import dask.dataframe as dd
from dask.distributed import Client
client = Client('11.11.11.111:8786')
print(client)

The output shows dashboard 

    Client
    Scheduler: tcp://11.11.11.111:8786
    Dashboard: http://11.11.11.111:36124/status
    client = Client('11.11.11.111:8786')

    Cluster
    Workers: 16
    Cores: 16
    Memory: 44.70 GB

Now typing http://11.11.11.111:36124/status into a browser window takes me to the Dask Dashboard.
