What is Grafana?




Grafana is a visualization tool that allows you to see and analyze all of your metrics in one unified dashboard. Grafana can pull metrics from any source, such as Graphite and Prometheus, display that data, then enable you to annotate and understand the data directly in the dashboard.


Many businesses choose hosted Graphite because it has:

  • An extensive community of users who support each other.
  • Features that serve diverse cases, including those that involve analytics, predictions, and DevOps.
  • Intuitive graphs and charts that make it easy for people to understand time-series metrics.
  • An interface that makes it easy for new users to learn.
