The Connection Exception measurement report contains measurements that provide information about exceptions and unexpected messages and events for individual SCTP/TCP connections that are not specific to the Diameter protocol.
| Measurement Tag | Description | Collection Interval |
|---|---|---|
| EvConnCerValFail | The number of times a CER contained invalid or unsupported AVP or AVP value. | 5 min |
| EvConnCexIpChkFail | The Host-IP-Address AVP(s) received in a CER or CEA message from the peer did not match the actual peer connection’s IP address(es). | 5 min |
| EvConnCnxFail | Number of times the transport connection attempt failed. This includes only unsuccessful attempts to connect to the peer; it does not include failure of established connections. | 5 min |
| EvConnDnsFail | Number of times an attempt to resolve a peer’s FQDN to an IP address via DNS failed. | 5 min |
| EvConnFarEndClose | Number of times the far end closed the connection. | 5 min |
| EvConnManClose | Number of times the connection was manually closed via administratively Disabling the connection locally. | 5 min |
| EvConnPeerNumIpFail | The peer has advertised in the INIT/INIT_ACK chunk a number of IP addresses different from the number of IP addresses the peer has been configured with in the respective connection object. | 5 min |
| EvConnRelease | The number of times the connection was terminated based on a connection release request from DRL | 5 min |
| EvConnSockInitFail | Number of times the socket initialization failed. | 5 min |
| EvConnTransFail | The number of times the connection was closed due to SCTP/TCP transport failure. | 5 min |
| RxConnGapAckBlocks | The number of gap acknowledgement blocks received on the SCTP connection. | 5 min |
| TxConnRetransDataChunks | The number of retransmitted data chunks sent on the SCTP connection. | 5 min |
| RxConnDupPkts | The number of duplicate packets received on the TCP connection. | 5 min |
| TxConnRetransSegs | The number of retransmitted segments sent on the TCP connection. | 5 min |
| TxConnSendFail | Number of times the transport send failed for any message on an established connection. When this occurs, the transport connection will NOT be disconnected. | 5 min |
