## About
|
|
|
|
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
