Grafana

Grafana is an open-source data visualization and dashboarding platform that connects to a wide range of data sources, including Prometheus, InfluxDB, Elasticsearch, and SNMP collectors, and displays the data in customizable, real-time dashboards. In network engineering, it is commonly used to visualize metrics like interface traffic, packet loss, latency, and device health collected from monitoring tools. Grafana does not collect data itself but excels at making complex time-series data understandable through graphs, gauges, and alerts.
