+Prometheus is a systems and service 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
+- pushing timeseries is supported via an intermediary gateway
+- targets are discovered via service discovery or static configuration
+- multiple modes of graphing and dashboarding support
+- support for hierarchical and horizontal federation
