## Source excerpt

Prometheus is a simple and effective open-source monitoring system. In the years after we published the article Monitoring Microservices with Prometheus, the system has graduated from the Cloud Native Computing Foundation (CNCF) and became the preferred monitoring tool for distributed systems. One of the reasons for this, as mentioned in our previous article, is its intuitive simplicity. It doesn't try to do anything fancy. It provides a data store, data scrapers, an alerting mechanism and a very simple user interface.
