Prometheus is a systems and services monitoring system. It collects metrics from configured targets at given intervals, evaluates rule expressions, displays the results, and can trigger alerts if some condition is observed to be true.
Prometheus’ main distinguishing features as compared to other monitoring systems are:
- A multi-dimensional data model (timeseries defined by metric name and set of key/value dimensions).
- A flexible query language to leverage this dimensionality.
- No dependency on distributed storage; single server nodes are autonomous.
- Timeseries collection happens via a pull model over HTTP.

- Targets are discovered via service discovery or static configuration.
- Multiple modes of graphing and dashboarding support.
- Federation support coming soon.
