Prometheus's 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
- PromQL, a **powerful and 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
- **pushing timeseries** is supported via an intermediary gateway
