Prometheus Server, part of the Cloud Native Computing Foundation project, is an innovative system and service monitoring solution. By regularly collecting metrics from designated targets, evaluating rule expressions, and displaying the results, Prometheus provides comprehensive insights into your operations. The software also has an alert system that triggers notifications when certain conditions are observed.

The key features that set Prometheus apart from other monitoring systems include its multi-dimensional data model. This allows time series to be defined by a metric name and a set of key/value dimensions, providing more in-depth analysis options. In addition to this, it uses PromQL - a flexible and powerful query language that leverages this dimensionality for more efficient data processing.
Prometheus is designed with independence in mind; it has no dependency on distributed storage as individual server nodes are autonomous. This approach allows for multiple modes of graphing and dashboarding support. Time series collection operates on an HTTP pull model, although pushing time series is also available via an intermediary gateway for batch jobs. With support for both hierarchical and horizontal federation as well as options for target discovery via service discovery or static configuration, Prometheus provides a versatile solution for systems monitoring.
