Gain metrics and receive alerts with this open-source monitoring tool.

Prometheus is an open-source systems monitoring and alerting toolkit part of the Cloud Native Computing Foundation . Since its inception in 2012, many companies and organizations have adopted Prometheus, and the project has a very active developer and user community. Prometheus's main features are: - a multi-dimensional data model with time series data identified by metric name and key/value pairs - PromQL, a flexible query language to leverage this dimensionality - no reliance on distributed storage; single server nodes are autonomous - time series collection happens via a pull model over HTTP - pushing time series is supported via an intermediary gateway - targets are discovered via service discovery or static configuration - multiple modes of graphing and dashboarding support
