Recently, I set up Jupyter Notebooks on a server at work. The idea was to create an enviroment where every team member could run analyses using Python and share the results with the rest. After reading the documentation, I found out that the Jupyter Notebook web application comes with a Contents API I quickly put together a little Munin script that collects some statistics about the current notebooks. The graph shows the total number of notebooks on the server as well as the currently open notebooks:
I have been using Munin to monitor the health of my Raspberry Pi for while now. As I have more devices installed in my network I was looking for a way to monitor these devices as well. As Munin uses a client-server model you are required to install the Munin node on the device to be monitored. Every five minutes the Munin server polls its clients for the values and creates charts using RRDTool.
