According to the log statistics, the number of interface calls is less than 1,000.

### Expected Behavior

null

### Error Logs

null

### Steps to Reproduce

null

### Environment

- APISIX version 3.11
- Operating system: Centos 7.9.x linux
- Apisix install by helm

Start with the two Prometheus queries in the issue and inspect the linked dashboard, then compare their service and route rates with the request counts from the logs. No source files or tests are identified; done means determining why APISIX 3.11 reports inflated metrics and confirming the corrected counts against logs.
