Do you maintain Windows Servers? If so, you might want to track server resources. ThingSpeak accepts data from anything and fits perfectly for server monitoring, visualization, and analysis. [NotHans] released a PowerShell Script to report Windows Server disk free space to ThingSpeak. Once in ThingSpeak, use a ThingSpeak to visualize server resources and send alerts to low disk space with ThingSpeak React. Use this PowerShell Script as a starter script to send data to ThingSpeak from Windows-based systems. Check out the open source script on GitHub.
