### Before Creating the Enhancement Request - [x] I have confirmed that this should be classified as an enhancement rather than a bug/feature. ### Summary In BrokerContainer mode, multiple broker instances share static metrics variables from `BrokerMetricsManager` and `DefaultStoreMetricsManager`, leading to data conflicts and resource leaks during dynamic broker operations. ### Motivation ## Root Cause Static metrics variables in `BrokerMetricsManager` and `DefaultStoreMetricsManager` are shared across all broker instances in the same JVM, causing: 1. **Metrics Data Conflicts**: Multiple broker instances write to the same static metrics variables 2. **Resource Leaks**: Frequent `addBroker`/`removeBroker` operations don't properly clean up metrics resources 3. **Incorrect Aggregation**: Metrics from different brokers are incorrectly mixed together 4. **Memory Leaks**: Static references prevent proper garbage collection ## 🚨 Impact - **Data Integrity**: Inaccurate metrics reporting for individual brokers - **Resource Management**: Memory leaks in long-running container environments - **Operational Issues**: Incorrect monitoring and alerting based on mixed metrics - **Scalability**: Prevents proper isolation in multi-tenant scenarios ## 🔧 Expected Behavior 1. Each broker instance should maintain independent metrics 2. Metrics should be properly isolated between different brokers 3. Dynamic broker addition/removal should not cause resource leaks 4. Metrics collection should work correctly in BrokerContainer mode ### Describe the Solution You'd Like Resolve critical metrics conflicts and resource leaks in BrokerContainer mode by converting static metrics variables to instance-level variables, ensuring proper isolation between multiple broker instances. ### Describe Alternatives You've Considered No ### Additional Context No -- This is an automated message from the Apache Git Service.
