How to Log and Track Client Disconnection Events in JupyterLab?

JupyterLab

Hello,

I’m experiencing an issue with JupyterLab where, upon losing connection to the Jupyter server, the browser displays the following message:

A connection to the Jupyter server could not be established. JupyterLab will continue trying to reconnect. Check your network connection or Jupyter server configuration.

We have built a platform that uses JupyterLab to allow users to write code online. It’s crucial for us to understand the network disconnection patterns our users experience during their sessions. This information will help us enhance the reliability and user experience of our platform.

Here are my specific questions:

  1. Does JupyterLab automatically log client disconnection events on the server?
  2. If not, are there recommended methods or tools to capture and record these events?
  3. Is it possible to achieve this through configuration changes or by writing custom scripts?

I have attempted to increase the server log level but haven’t found any relevant disconnection records. Any suggestions or guidance would be greatly appreciated!

Thank you!
