org.apache.hivemind.management.mbeans.PerformanceMonitorMBean
public class PerformanceMonitorMBean
MBean that holds and calculates the performance data for service method calls intercepted by the
performanceMonitor
interceptor. Creates for each intercepted method 5 MBean attributes: Number of Calls, Minimum,
maximum, average and last execution time
