I want to investigate what caused a high cpu usage for several hours on 1/16. Digital Ocean graph shows a prolonged high cpu usage in the course of about 12 hours. Is there a log somewhere that I can tap into that would reveal to me more detail about this issue?

Digital Ocean doesn't logs your processes. This will mess up with your VM and privacy.
You have to log these on your own inside your VM. One of the options is to use atop tool, it can start as a daemon and log usage stats into a file. There a lot of other options actually.
Digital Ocean even have an article on this: https://www.digitalocean.com/community/tutorials/how-to-monitor-cpu-use-on-digitalocean-droplets
But it actually offers to enable alerts on total CPU usage with their tools and later use a top tool for real-time analysis. I think atop record usage to a file approach are more feasible.
