Hello everyone, for some time now I have been working together with my research team using different fiware components. After putting on ORION, using MongoDB for writing context data, I thought of using Grafana to show in real time data sent to ORION and stored on Mongo (For example data from a sensor). I was wondering what would be the best method to connect Grafana to ORION, considering that the free version does not offer a connector to MongoDB. Currently through a plugin, on Grafana, I can call the API exposed by the context broker to retrieve the data and then build the tables and the different charts. I wanted to know if this is a good practice or there are better ways, thanks!
