**Issue Evaluation** Category: `bug` | Status: **Confirmed** The reported issue has been verified against the current codebase. **Root Cause:** In `PopMessageProcessor.java`, when `popConsumerKVServiceEnable=true` (line 380), the code takes an async path via `popConsumerService().popAsync()`. The result is processed in a `thenApply` callback that handles the response but does not call any stats methods (`incBrokerGetNums`, `incGroupGetNums`, etc.). In contrast, the traditional POP path (line 792) correctly calls `incBrokerGetNums(topic, result.getMessageCount())`. The KV POP path is missing these metric updates entirely. **Impact:** When KV POP is enabled: - `mqadmin consumerProgress` reports Consume TPS as 0 - `BROKER_GET_NUMS`, `GROUP_GET_NUMS`, `GROUP_GET_SIZE` are not updated - OTel metrics `rocketmq_messages_out_total` and `rocketmq_throughput_out_total` are inaccurate **Severity:** Medium — monitoring and observability are broken for KV POP mode. **Suggested Fix:** Add the same stats increment calls in the KV POP `thenApply` callback that exist in the traditional POP path (around line 792). An automated fix proposal can be generated. Reply `/approve` to proceed with PR generation. --- *Automated evaluation by github-manager* -- This is an automated message from the Apache Git Service.
