I need to analyze the data stored in the database. For this reason I want to visualize the data for better understanding. This is also an advantage if external people need an overview of the data. For this purpose I did some research and there are some open source visualization tools. I would then manage them using the cloud service Aiven. Graphite seemed to be popular, but the problem is that I can’t access multiple data sources, so I never have all the data available. One tip I got was Grafana. However, Grafana is a bit more complex than Graphite, and I don’t know if that would be too extensive - but it would also be open source, so you could at least test it. As far as I understood, I can access several data sources with Grafana and even have the data displayed in charts.
Has anybody ever made any experiences with Grafana? Can you recommend it?
