The Diameter Exception measurement report contains measurements that provide information about exceptions and unexpected messages and events that are specific to the Diameter protocol.
| Measurement Tag | Description | Collection Interval |
|---|---|---|
| EvApplIdListInconsistency | Number of times that the supported Application IDs received from the Peer were Inconsistent with another Transport Connection | 5 min |
| EvConnCeaIdValFail | Number of times the connection was closed due to CEA Realm/Host validation for locally initiated connections. Note: CER Realm/Host validation failures are tracked via the EvConnCerIdValFail measurement and are NOT included in this measurement.

5 min |
| EvConnCexTO | Number of times the connection timed out waiting for the peer to send a CER or CEA. | 5 min |
| EvConnDpaTO | Number of times the connection timed out waiting for the peer to send a DPA. | 5 min |
| EvConnNoComnApps | Number of times the connection was closed due to there being no common application IDs existing between the local and peer nodes. | 5 min |
| EvConnPrvFail | Number of times the connection was closed after failing to successfully complete the proving phase. | 5 min |
| EvConnRejected | Number of times the connection was rejected. Reasons include IP addresss validation failure, the connection already established, and connection Administratively Disabled. | 5 min |
| EvConnRejInsufficientIngressMps | Number of times DA-MP rejected a Diameter connection due to insufficient Ingress MPS on the DA-MP to support the Reserved Ingress MPS configured for the connection. | 5 min |
| EvConnRejMaxConnExceeded | Number of times DA-MP rejected a Diameter connection due to the DA-MP exceeding its maximum number of supported Diameter connections. | 5 min |
| EvConnWdFail | Number of times the Diameter Watchdog algorithm closed the connection due to no traffic received from the peer within Tw*2 time after a DWR was sent. | 5 min |
| EvConnWdSuspect | Number of times the Diameter Watchdog algorithm declared the connection suspect due to no traffic received from the peer within Tw time after a DWR was sent. | 5 min |
| EvMpCerIdValFail | Number of times the connection was closed due to CER Realm/Host validation for peer initiated connections. | 5 min |
| EvTransLifetimeExceededMp | Number of transaction failures because “Transaction Lifetime” exceeded. | 5 min |
| RxAnswerMsgQueueFullDiscard | Number of ingress Diameter Answer messages that were discarded because the Answer Message Queue was full. | 5 min |
| RxAnswerUnexpected | Number of valid Answer messages received from an upstream peer that could not be associated with a pending transaction | 5 min |
| RxConnCeaError | Number of CEA error messages received on the connection. | 5 min |
| RxConnFailMalfMsg | Number of messages received on the connection which were malformed. Malformed messages cause the connection to be closed. | 5 min |
| RxConnInvalidMsg | Number of messages received on the connection which had a semantic error. Messages with semantic errors are discarded. | 5 min |
| RxConnMpCongestionAnswerRsp | Number of ingress messages that were rejected with an error response because of local congestion. | 5 min |
| RxConnUnexpCex | Number of unexpected CER/CEA messages received on the connection. | 5 min |
| RxConnUnexpDpx | Number of unexpected DPR/DPA messages received on the connection. | 5 min |
| RxConnUnexpDwx | Number of unexpected DWR/DWA messages received on the connection. | 5 min |
| RxMaxMpsAnswerRsp | The number of ingress Diameter messages that were discarded because of the MP Maximum MPS limitation and an Answer response was sent. | 5 min |
| RxMaxMpsRejectMp | The number of ingress Diameter messages that were rejected because of MP Maximum MPS limitation and an Answer response was sent. | 5 min |
| RxMpCongestionDiscardMp | The number of ingress Diameter Request messages received that were discarded or rejected because of local MP congestion. | 5 min |
| RxMpCongestionRejectMp | The number of ingress Diameter messages that were discarded because of Local MP Congestion and an Answer response was sent. | 5 min |
| RxMsgsOCGreenPri0DiscardMp | The number of Green ingress Priority 0 messages discarded by the DA-MP Overload Control component. | 5 min |
| RxMsgsOCYellowPri0DiscardMp | The number of Yellow ingress Priority 0 messages discarded by the DA-MP Overload Control component. | 5 min |
| RxMsgsOCGreenPri1DiscardMp | The number of Green ingress Priority 1 messages discarded by the DA-MP Overload Control component. | 5 min |
| RxMsgsOCYellowPri1DiscardMp | The number of Yellow ingress Priority 1 messages discarded by the DA-MP Overload Control component. | 5 min |
| RxMsgsOCGreenPri2DiscardMp | The number of Green ingress Priority 2 messages discarded by the DA-MP Overload Control component. | 5 min |
| RxMsgsOCYellowPri2DiscardMp | The number of Yellow ingress Priority 2 messages discarded by the DA-MP Overload Control component. | 5 min |
| RxPduPoolEmptyDiscard | The number of Diameter messages that were discarded because no PDU Buffers were available. | 5 min |
| RxRoutableRejectMsgsMp | The number of ingress Diameter Request messages received that are rejected by MP with Error Answer due to MP Overload Control or Maximum IMR Limitation. | 5 min |
| TmConnDegraded | Total time (in seconds) during the reporting period that the connection state was in the Degraded state. | 5 min |
| TmConnEnabledNotAvail | Total time (in seconds) during the reporting period that the connection state was Administratively Enabled and the connection state was not Available. | 5 min |
| TxAllConnQueueFullAnswerDiscard | The number of egress Diameter Answer messages that were discarded because the All-Connections Event Queue was full and an Answer response was sent. | 5 min |
| TxAllConnQueueFullDiscard | Number of egress Diameter messages that were discarded because the All-Connections Event Queue was full. | 5 min |
| TxConnCeaError | Number of CEA error messages sent on the connection. | 5 min |

| TxReqMsgApplMismatch | Number of times message routing detected application mismatch | 5 min |
| TxReqMsgPerConnPtrMax | Number of times message routing bypassed the connection because the maximum allowed pending transactions was exceeded | 5 min |
| TxRequestEgressLoop | Outgoing message loops detected | 5 min |
