Prometheus is an open-source systemsmonitoring and alerting toolkit originally built atSoundCloud. Since its inception in 2012, manycompanies and organizations have adopted Prometheus, and the project has a veryactive developer and user community. It is now a standalone open source projectand maintained independently of any company. To emphasize th...
Prometheus works well for recording any purely numeric time series. It fitsboth machine-centric monitoring as well as monitoring of highly dynamicservice-oriented architectures. In a world of microservices, its support formulti-dimensional data collection and querying is a particular strength. Prometheus is designed for reliability, to be the syste...
Prometheus values reliability. You can always view what statistics areavailable about your system, even under failure conditions. If you need 100%accuracy, such as for per-request billing, Prometheus is not a good choice asthe collected data will likely not be detailed and complete enough. In such acase you would be best off using some other system...
Data model | Prometheus. Metric names and labels. Samples. Notation. Prometheus fundamentally stores all data as time series: streams of timestamped values belonging to the same metric and the same set of labeled dimensions. Besides stored time series, Prometheus may generate temporary derived time series as the result of queries.
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.
We provide precompiled binaries and Docker images for most officially maintained Prometheus components. If a component is not listed here, check the respective repository on Github for further instructions.
