I will explain easy and comprehensive way to install and setup Prometheus and Grafana in AKS (Azure Kubernetes Service). In Kubernetes eco-system, the monitoring and alerting get handled by Prometheus and Grafana. The main purpose of Prometheus is to gather monitoring logs, but it is not user-friendly to visualize data in Prometheus. Grafana is to help you visualize the log data because it is fairly easy to visualize log data in Grafana. One of the shortcomings of Grafana is that it cannot gather and store monitoring log data. Therefore, Prometheus and Grafana complement each other and usually work together in Kubernetes environment.
