Suggest a Fix

I just need to add the following properties
management.metrics.tags.application: ${spring.application.name} in application.yml
Maybe is there a better way? using metric registry?

See below picture of prometheus before and after fix. We can that "application" is sent after the fix (first row in the capture)
