Recall & Review

beginner

What is Grafana used for in Kubernetes?

Grafana is used to create visual dashboards that show metrics and logs from Kubernetes clusters. It helps you understand the health and performance of your apps and infrastructure.

beginner

How does Grafana get data to display?

Grafana connects to data sources like Prometheus, which collects metrics from Kubernetes. It queries these sources to get data and then shows it in charts and graphs.
