[Bug] Proxy client settings cleaner logs full gRPC Settings

[Aias00]

Problem

GrpcClientSettingsManager logs full gRPC Settings protobufs from the periodic unused-settings cleanup path.

Evidence:

• proxy/src/main/java/org/apache/rocketmq/proxy/grpc/v2/common/GrpcClientSettingsManager.java logs settings:{} when removing unused gRPC client settings.

Impact

This is in the RocketMQ Studio Track 2 / Proxy Admin diagnostics scope. Full Settings can include detailed publish/subscription metadata. Cleaner logs should not dump those payloads.

Expected

The cleaner log should use a compact summary such as client type and publish/subscription counts instead of full protobuf output.

Issue Evaluation

Category: type/bug | Status: Confirmed

Verified against the current codebase on develop branch.

Root Cause: GrpcClientSettingsManager logs the full Settings protobuf in the periodic cleanup path:

• Line ~285: log.info("remove unused grpc client settings. group:{}, settings:{}", consumerGroupInfo, settings)

This fires during the doClean cycle for stale client entries. The Settings object can contain detailed publish/subscription metadata.

Impact: Periodic information leakage through info-level logs. Every cleanup cycle dumps full Settings for each removed client.

Severity: medium — no functional impact, but cleaner logs should use a compact summary instead of full protobuf output.

Suggested Fix: Replace settings in the log with a compact summary (e.g., client type, publishing topic count, subscription count).
