We don't really have tutorials. You can find documentation on how to set up the agents at https://www.elastic.co/guide/en/apm/agent/index.html, as well as some more information on https://www.elastic.co/blog, e.g.
- https://www.elastic.co/blog/elastic-apm-java-agent-is-generally-available
- https://www.elastic.co/blog/creating-custom-framework-integrations-with-the-elastic-apm-python-agent
There are tutorial-style walkthroughs around the web. I can't recommend any in particular, but this one looks like it might be a good place to start: https://medium.com/@sece.cosmin/monitor-spring-boot-application-performance-with-elastic-apm-elasticsearch-and-kibana-8d4299cad2be.
