### Search before asking - [X] I had searched in the [issues](https://github.com/apache/skywalking/issues?q=is%3Aissue) and found no similar feature requirement. ### Description As the difference between MAL and OAL, some metrics would be separated, e.g. service cpm and k8s service cpm. On the query and/or alerting MQE setup, we may need a single expression for those metrics. So, I propose this function, `top_n_of(exp1, exp2, ...)` ### Use case Support to provide unified top N for multiple metric expressions. Note, the expression should keep the precious of those expressions same. Otherwise, top N would be incorrect. ### Related issues _No response_ ### Are you willing to submit a pull request to implement this on your own? - [ ] Yes I am willing to submit a pull request on my own! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
