JMX Console

Implementation Strategy

Extend JVM monitoring capabilities by implementing custom JMX interfaces for application-specific metrics like transaction rates, cache hit ratios, and latency baselines.

Code Example

public class TransactionMonitor implements DynamicMBean {
    private ObjectName name;
    private HashMap metrics = new HashMap<>();
    
    public Object getAttribute(String name) throws Exception {
        if ("TransactionCount".equals(name)) return getTotalTransactions();
        // additional metrics...
    }
    
    public MBeanInfo getMBeanInfo() {
        MBeanAttributeInfo[] attr = new MBeanAttributeInfo[] {
            new MBeanAttributeInfo("TransactionCount", "int", "Total transactions", true, false, null),
            new MBeanAttributeInfo("AverageLatency", "double", "Average call duration", true, false, null)
        };
        return new MBeanInfo(this.class, "Transaction Metrics", attr, new MBeanOperationInfo[0]);
    }
}
