I manage a lot of servers. One of the things that I am always curious about is how much disk space is left on my servers. I know there are a lot of ways to track this, but almost always it seems the service that I am using changes on me or breaks over time.
My super simple solution for tracking server disk space is to use Windows PowerShell and ThingSpeak. I went to the trouble to release the code to GitHub, so that you can try this out for yourself. This can be used on any Windows Server as long as you have the ability to execute PowerShell scripts. ThingSpeak gives you a place to store data from anything. In this case, I am sending my disk free space to ThingSpeak once per day by scheduling a Windows Task.
