Grafana Labs is adding two new productsPhlare and Faroto its observability stack to optimize infrastructure profiling and application observability. Before we do anything else, lets use git: If you havent done so, run the Grafana server, if you are using docker, you can use docker restart grafana. The base template suggests to use an instance manager for the life cycle management of data source instances. On top of that, we're going to create a specific user that has specific permissions for the database we'll view on Grafana. Use docker-compose exec -u 0 grafana /bin/bash to get a shell in the container. Todo that you will need to edit src/DataSource.ts.
