+**Netdata** is **distributed, real-time, performance and health monitoring for systems and applications**. It is a highly optimized monitoring agent you install on all your systems and containers.
 
 Netdata provides **unparalleled insights**, **in real-time**, of everything happening on the systems it runs (including web servers, databases, applications), using **highly interactive web dashboards**.  It can run autonomously, without any third party components, or it can be integrated to existing monitoring toolchains (Prometheus, Graphite, OpenTSDB, Kafka, Grafana, etc).
