What are Prometheus Functions?
Prometheus is a platform for real-time systems and event monitoring and alerting. The Prometheus project is free, open-source, and available on GitHub. Originally developed at SoundCloud, Prometheus became a project of the Cloud Native Computing Foundation in 2016, alongside other popular frameworks such as Kubernetes. The core of the project is the Prometheus server, which acts as the system’s “brain” by collecting various metrics and storing them in a time-series database.
