The Prometheus monitoring system and time series database.

Visit prometheus.io for the full documentation, examples and guides.

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 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
