Usually, Java applications use databases as storage. With an already working app, it's not necessarily so easy to support and maintain.

You'll see information about Java, system, and database in one system, and will be able to analyze it,
We'll see the latest version of Percona Monitoring and Management system (PMM) and combine it with JMX exporter to get data from Java metrics. All of these will be collected in Prometheus. We'll review dashboards and see how to make your own dashboards.
