management.metrics.tags doesn't work in Spring Boot 3.2.1 version

[pavel-zeger]

Hello!

Following this closed issue I would like to report the bug with the management.metrics.tags used together with observation property management.observations.key-values: #38583.

Downgrading to the previous Spring Boot 3.1.6 version clearly shows the added metric tag when I check /actuator/prometheus endpoint. Upgrading to 3.2.1 eliminates any metrics tag (also default metrics like process_uptime_seconds and etc.) added via management.metrics.tags property.

I use both options: observations for controllers (with ObservedAspect) and custom tags for other metrics with management.metrics.tags property.

If management.metrics.tags isn't working for you, I don't think it's related to the changes in #38583. That issue did not make any functional changes, it only removed the deprecation of the property. I also don't see the connection between default tags and default metrics such as process_uptime_seconds. The former should have no affect on whether or not the latter is present.

If you would like us to spend some more time investigating, please spend some time providing a complete yet minimal sample that reproduces the problem. You can share it with us by pushing it to a separate repository on GitHub or by zipping it up and attaching it to this issue.

I'll try to reproduce it outside my production service and publish it here. Thank you for the fast response.
