As our microservice systems have grown in size and complexity, discovering and investigating issues has become more and more difficult. If you're willing to pay for it, there are plenty of choices (Datadog, Splunk, New Relic, etc.) to help. However, there are also open source solutions that can give you increased control and cut your costs.

In this talk we'll setup and explore a Grafana stack. Then we'll create some Spring Boot apps and configure them to share their log, metric, and trace data with Grafana.

At the end of the talk attendees will have a basic understanding of what Grafana is and how to get data into it. They should then be empowered to apply these lessons to add observability where there is none or replace expensive SAAS solutions with free open source alternatives.
