Prometheus
Prometheus is a popular tool that helps companies keep track of how well their computer systems and applications are running. Think of it like a digital dashboard that shows important measurements - like how much memory a program is using, how fast websites are loading, or if there are any problems with servers. It's particularly useful in modern technology setups where companies run lots of different applications across multiple computers or cloud services. When you see Prometheus mentioned in a resume, it usually means the person has experience with monitoring and maintaining the health of computer systems.
