![]() ![]() ![]() ![]() Dashboard provides an end-user a visualization of quired data-points as we discover later in the text. The article focuses on utilizing the metrics and provisioning the subsystem data into the Grafana dashboard. In this article we review monitoring abilities for different JVM based frameworks (Quarkus, Spring, KTor and Micronaut ) by using popular open source tools like Grafana, Prometheus and Micrometer. Observability may become a crucial feature here also as it serves the information of properly executed steps and statuses. The fact that an application is divided into subsystems influences the deployment strategy and raises requirements on the proper configuration. The whole collection then appears to the end user as a single coherent system. These subsystems communicate between each other by passing messages (signals) and executing desired actions to each other. A cloud based application is usually set up as the collection of different subsystems that may be located in one or more network zones or machines. In the time of cloud and distributed applications it is becoming more and more important to be able to evaluate a functionality at runtime, an aspect which is referred to as observability.
