How to figure out info about running server from python

[paddymul]

Problem

I want to figure out how to determine the running jupyter lab server from python. Then I want to determine the start time of that server.

Proposed Solution

what code do I need after this

from IPython import get_ipython
ip = get_ipython()

Additional context

Why?

I am a widget library author, and my users frequently get the "widget: model not found" error message and are then lost.

With the server uptime info, and figuring out the MTime of the widget package, I can determine if the package was installed after the server started, then recommend users restart their jupyter lab server to see the new extension in action.

The command I wanted was

    parent_process = psutil.Process().parent()
    server_start_time = dtdt.fromtimestamp(parent_process.create_time())
