You can use the Object Request Broker (ORB) counters that the Performance Monitoring Infrastructure (PMI) and Tivoli Performance Viewer (TPV) collect to monitor ORB operations.
Name | Key | Description | Granularity | Type | Level | Overhead |
LookupTime | orbPerfModule.referenceLookupTime | The time (in milliseconds) to look up an object reference before method dispatch can be carried out. An excessively long time can indicate an EJB container lookup problem. | Object Request Broker (ORB) | TimeStatistic | All | Medium |
RequestCount | orbPerfModule.totalRequests | The total number of requests sent to the ORB | ORB | CountStatistic | All | Low |
ConcurrentRequestCount | orbPerfModule.concurrentRequests | The number of requests that are concurrently processed by the ORB | ORB | RangeStatistic | All | High |
ProcessingTime | orbPerfModule.interceptors.processingTime | The time (in milliseconds) it takes a registered portable interceptor to run | Per interceptor | TimeStatistic | All | Medium |
