It’s been a while since I last got to work with a Linux cluster, so I decided to build an affordable cluster of raspberry Pi computers. It took an entire afternoon to build! The cluster had 16 cores, 4gb of ram, 128gb of storage, a whopping 16 usb ports and only cost about $200. How many clusters do you know with 16 usb ports?
I decided to set up my cluster for monitoring my computers using Telegraf to report statistics like CPU and Memory usage.
