%description
Prometheus's main features are:
 - a multi-dimensional data model (time series identified by metric name and key/value pairs)
 - a flexible query language to leverage this dimensionality
 - no reliance on distributed storage; single server nodes are autonomous
 - time series collection happens via a pull model over HTTP
 - pushing time series is supported via an intermediary gateway
 - targets are discovered via service discovery or static configuration
 - multiple modes of graphing and dashboarding support
