The Connection Performance measurement report contains measurements that provide performance information for individual SCTP/TCP connections that are not specific to the Diameter protocol.
| Measurement Tag | Description | Collection Interval |
|---|---|---|
| EvConnCnxSuccess | Number of times the transport connection was successfully established. In instances where two connections are established and one is disconnected after an election, both connection establishments are counted. | 5 min |
| EvPerConnQueueCongestionChange | Number of times that the congestion level changed for a Connection. | 5 min |
| RxConnAvgMPS | Exponentially smoothed average rate in MPS on the connection. Note: This measurement will be sampled periodically and reported in the Connections Maintenance GUI as a type of KPI. | 5 min |
| RxConnMsgs | Number of messages received on the connection. This includes all Diameter messages, both routable and non-routable. | 5 min |
| RxConnOctets | Number of octets received on the connection. This includes Diameter payload octets for all Diameter messages, both routable and non-routable. | 5 min |
| RxConnPeakMPS | Peak rate of the exponentially smoothed average rate in MPS on the connection | 5 min |
| RxConnRecvBufAvg | Average number of bytes in the SCTP/TCP receive buffer. The bytes in the receive buffer are those received from the peer but not yet read by the peer state machine. | 5 min |
| RxConnRecvBufPeak | Peak number of bytes in the SCTP/TCP receive buffer. The bytes in the receive buffer are those received from the peer but not yet read by the peer state machine. | 5 min |
| RTxConnTotalDataChunks | The number of total data chunks received on the SCTP connection. | 5 min |
| RxMsgRateAvg | Average Connection Ingress Message Rate. | 5 min |
| RxMsgRatePeak | Peak Connection Ingress Message Rate. | 5 min |
| RxSctpChunkMp | Number of SCTP data chunks received by the MP (excluding duplicates). | 5 min |
| RxSctpPacketMp | Number of SCTP packets received by the MP (excluding duplicates). | 5 min |
| TmRxMPSDelay_MaxCapacity | Total amount of time during the measurement reporting interval that the connection experienced delay in ingress message processing because the ingress message rate on the connection exceeded the connection’s configured Maximum Ingress MPS | 5 min |
| TmRxMPSDelay_SharedCapacity | Total amount of time during the measurement reporting interval that the connection experienced delay in ingress message processing due to no capacity available in the MP server’s shared ingress MPS pool | 5 min |
| TxConnMsgs | Number of messages sent on the connection. This includes all Diameter messages, both routable and non-routable. | 5 min |
| TxConnOctets | Number of octets sent on the connection. This includes Diameter payload octets for all Diameter messages, both routable and non-routable. | 5 min |
| TxConnSendBufAvg | Average number of bytes in the SCTP/TCP send buffer. The SCTP/TCP send buffer contains all bytes sent to the SCTP/TCP socket by the peer state machine which have not yet been sent to the peer or have been sent to the peer and have not been unacknowledged. | 5 min |
| TxConnSendBufPeak | Peak number of bytes in the SCTP/TCP send buffer. The SCTP/TCP send buffer contains all bytes sent to the SCTP/TCP socket by the peer state machine which have not yet been sent to the peer or have been sent to the peer and have not been unacknowledged. | 5 min |
| TxConnTotalDataChunks | The number of total data chunks sent on the SCTP connection. | 5 min |
| TxPerConnQueueAvg | Per Connection Egress Message Queue Average Utilization. | 5 min |
| TxPerConnQueuePeak | Per Connection Egress Message Queue Peak Utilization. | 5 min |
