Statistics
The following 25 statistics may be generated by N2SVCD Application “DnsClientApp”.
No statistics found that match search criteria.
N2::Application
| instance.throttle.max_instances | Message | Counter |
| Cause: | Maximum number of instances exceeding the max number of instances. |
| instance.throttle.max_tps_average | Message | Counter |
| Cause: | Average max TPS for the last throttle period. |
N2::Application::AppInstance
| instance.abort | Job, Message | Counter |
| Cause: | Application instances aborted due to receiving an unexpected shutdown/abort message. Depending on the application, an "instance" may represent a transaction, call, session, request/response pair, etc. Note that aborted instances are still counted in instance.shutdown. |
| instance.shutdown | Job, Message | Counter |
| Cause: | Application instances shut down (for any reason, including abort). Depending on the application, an "instance" may represent a transaction, call, session, request/response pair, etc. The difference between this statistic and instance.start represents the current number of active instances being handled by this application. |
| instance.start | Job, Message | Counter |
| Cause: | Application instances started. Depending on the application, an "instance" may represent a transaction, call, session, request/response pair, etc. The difference between this statistic and instance.shutdown represents the current number of active instances being handled by this application. |
N2::Application::TcpApp
| send.request.error.abandon | Job, Message | Counter |
| Cause: | Outbound messages abandoned due to send failure(s). |
| send.request.error.offline | Job, Message | Counter |
| Cause: | Outbound messages not sent due to client being offline. |
| send.request.retry | Job, Message | Counter |
| Cause: | Outbound messages retrying after timeout or disconnection. |
