Spring Security Observability Samples
Run these samples see Spring Security's intregration with Micrometer in action.
They are based off of Spring Security defaults, so in each case you can either go to http://localhost:8080 in the browser or to localhost:8080 from the command line.
An easy way to see the metrics is to get Zipkin running.
And an easy way to do that is using Jonathan Ivanov's docker compose configuration.
Once both the sample app and Zipkin is up and running, use the application and then browse to http://localhost:9411 where you can search for and see Spring Security timings and events.
