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 |
