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
