I am not sure if this will be the best and most elegant way to achieve this but it's probably a fair solution.
My suggestion is to write a PyCharm plugin, that will use OS commands underneath to find out what you are looking for (CPU usage for example) and then send this periodically to admin over time along with the PC hostname/identifier.
I understand that this is not the easiest way to do it and will require some development, but if you are willing to spend time on it and if what you are looking for is possible to be implemented as a plugin for the IDE, you could potentially come up with a very powerful plugin for the needs of your company, in my opinion.
I don't have any experience with JetBrains plugins for any of their IDEs so I don't know anything technically about writing JetBrains plugins; it could be that what I suggest is not possible, but I thought to share this idea, should be useful to you.
