### 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 This is my scenarioļ¼ 1. otel-collector scrape gateway metric endpoint in every 15S 2. skywalking mal engine calculate every http code count increasement in this 15s and downsampling by sum method 3. skywalking will persist this metric in meter_sum_xxxxxxxx table in value meter mode ``` metricsRules: - name: http_200_code_count exp: http_server_requests_seconds_count.tagEqual('status', '200').sum(['application']).increase('PT15S').service(['application'], Layer.GENERAL).downsampling(SUM) - name: http_404_code_count exp: http_server_requests_seconds_count.tagEqual('status', '404').sum(['application']).increase('PT15S').service(['application'], Layer.GENERAL).downsampling(SUM) ... ... ... ``` ### Use case I want to change my mal like this, the sum aggregate method use 'application' and 'status' as aggregate-by params. If skywalking meter system support sumlabeled function, this metric will be persisted in meter_sumlabeled_xxxxxxxx table in datatable meter mode. The sumlabeled function is easy to extend under skywalking meter system excellent architecture design, and it can bring us benefits in query efficiency and storage economy. ``` metricsRules: - name: http_code_count exp: http_server_requests_seconds_count.sum(['application','status']).increase('PT15S').service(['application'], Layer.GENERAL).downsampling(SUM) ``` ### Related issues _No response_ ### Are you willing to submit a PR? - [X] Yes I am willing to submit a PR! ### 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.
