About Prometheus

Prometheus is an open-source monitoring and alerting system designed for reliability and scalability. It collects metrics from configured targets at specified intervals, evaluates rule-based conditions, and triggers alerts when thresholds are crossed.

Metrics in Prometheus are stored as time series data, with each data point tagged by a timestamp and optional labels—key-value pairs that provide context such as host, service, or environment. Prometheus supports a powerful query language called PromQL, which lets you aggregate, filter, and analyze metric data in real time.
