How to log connection details when using voila stand alone?

[tonywang531]

I have been using voila for a while now, and it works great. However, I have been wondering how can I observe how many connections have been made during the day and ideally with timestamp as well? I am launching voila from anaconda prompt and I wish there is a way to log these things like the python logging module.

For now, this could be done outside voila by building metrics from a log of requests, for example if Voila is served behind a reverse proxy such as nginx:

GET /example.ipynb
GET /dashboard.ipynb
...

We could also check how to make use of the metrics from jupyter_server directly, once voila switches to being an ExtensionApp.
