+This app packages Prometheus <upstream>2.22.0</upstream>
+
+Prometheus, a Cloud Native Computing Foundation project, 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 when specified conditions are observed.
+
+## Features
+
+The features that distinguish Prometheus from other metrics and monitoring systems are:
+
+* A multi-dimensional data model (time series defined by metric name and set of key/value dimensions)
+* PromQL, a powerful and flexible query language to leverage this dimensionality
+* No dependency on distributed storage; single server nodes are autonomous
+* An HTTP pull model for time series collection
+* Pushing time series is supported via an intermediary gateway for batch jobs
+* Targets are discovered via service discovery or static configuration
+* Multiple modes of graphing and dashboarding support
+* Support for hierarchical and horizontal federation
+
