Grafana
Not exactly a BI tool, but can be used as such. But it is often more specialized for real-time data visualization and monitoring, particularly for time-series data, and may require add-ons for some traditional BI features like report automation.
It's often used together with Prometheus.
Prometheus: Acts as the "sensor system" that scrapes and stores metrics from your applications and infrastructure, such as CPU, memory, and network activity. It collects data over time, creating time-series data.
Grafana: Is the visualization platform. You add Prometheus as a "data source" in Grafana, pointing it to your Prometheus instance.
