COJUG - Application monitoring with Micrometer, Prometheus, and Grafana

Abstract

Tired of waiting for reports from users to let you know your application is having performance issues? If you’re looking for a way to increase visibility into your application beyond plain text logs, this is the talk for you!

In this talk you will be introduced to a suite of open source tools that you can use monitor the performance of your JVM based applications.

Micrometer is a metrics library from Pivotal (and the default metrics library for Spring Boot) that allows you to instrument your library once and export to many popular monitoring systems.

Prometheus is a monitoring and alerting tool that allows you easily store and query your application metrics with minimal operational overhead

Grafana is a visualization tool that allows you to easily generate and manage beautiful graphs and dashboards from data stored in Prometheus (as well as many other backends)
