In this guest blog post by Anjana Fernando, readers are guided through the process of visualizing metrics from a Ballerina service using Grafana, highlighting the installation and configuration steps necessary for this integration. Ballerina, a cloud-native programming language designed for microservice development, is known for its observability features, which are crucial for understanding system deployment states. The post explains how Ballerina utilizes Prometheus for metrics collection and how Grafana, a leading analytics visualization tool, is employed to create dashboards that display these metrics. Additionally, the post details how to set up a simple Ballerina service, configure Prometheus for metrics collection, and use Docker to run both Prometheus and Grafana. The visualization process is enhanced by Grafana's ability to query and display data from multiple sources, making it a robust solution for monitoring Ballerina services. The blog also mentions an invitation to the upcoming Ballerinacon event, offering Grafana community members access with a free ticket.
