You can create a Grafana dashboard to better understand what's happening in advance by querying data from various sources such as Prometheus and Loki. To get started with creating dashboards, you need to set up the necessary services using Docker Compose, import data from your desired data sources, and build queries that allow you to visualize this data. You can also add annotations to events to provide extra context about what's happening in your application, making it easier to identify problems and resolve issues faster. With Grafana dashboards, you can gain valuable insights into your data and make informed decisions to improve the performance of your applications.
