Use Object Request Broker counter to monitor ORB operations

Object Request Broker counters

Use the Object Request Broker (ORB) counters that the Performance Monitoring Infrastructure (PMI) and Tivoli Performance Viewer (TPV) collect to monitor ORB operations.

Counter definitions

Name Key Description Granularity Type Level Overhead ID
ConcurrentRequestCount orbPerfModule.concurrentRequests The number of requests that are concurrently processed by the ORB ORB RangeStatistic All High 3
LookupTime orbPerfModule.referenceLookupTime The amount of time, in milliseconds, (normally < 10 milliseconds) that it takes to look up an object reference before a method dispatch can be completed. An excessively long time might indicate that there is an EJB container lookup problem. Object Request Broker (ORB) TimeStatistic All Medium 1
RequestCount orbPerfModule.totalRequests The total number of requests sent to the ORB ORB CountStatistic All Low 2
ProcessingTime orbPerfModule.interceptors.processingTime The time (in milliseconds) it takes a registered portable interceptor to run Per interceptor TimeStatistic All Medium 11
