The "Communication Agent Exception" measurement group is a set of measurements that provide information about exceptions and unexpected messages and events that are specific to the Communication Agent protocol.
| Measurement Tag | Description | Collection Interval |
|---|---|---|
| CADataFIFOQueueFul | StackEvents discarded due to ComAgent DataFIFO queue full condition. | 30 min |

| CARxDscrdBundle | Number of ingress bundled event discarded during de-serialization | 30 min |
| CARxDscrdConnUnavail | Number of User Data ingress events discarded because connection was not in-service. | 30 min |
| CARxDscrdDecodeFailed | Number of ingress events discarded because failed to deserialize (event not part of stack service language). | 30 min |
| CARxDscrdIncompat | Number of ingress events discarded because an Incompatible header version is received. | 30 min |
| CARxDscrdInternalErr | Number of ingress events discarded because of other unexpected internal processing error. | 30 min |
| CARxDscrdLayerSendFail | Number of User Data ingress events discarded because layer’s sendTo failed. | 30 min |
| CARxDscrdMsgLenErr | Number of ingress events discarded as it doesn’t contain enough bytes (less than event header bytes). | |
| CARxDscrdUnkServer | Number of ingress events discarded because the origination server was unknown/not configured. | 30 min |
| CARxDscrdUnkStkLyr | Number of User Data ingress events discarded because stack layer is not known. | 30 min |
| CARxMsgUnknown | Number of ingress events discarded because stack event was unknown. | 30 min |
| CAStackQueueFul | StackEvents discarded due to ComAgent task queue full condition. | 30 min |
| CATransDscrdInvCorrId | Number of received stack events that were received and discarded because they did not correlate with a pending transaction. | 30 min |
| CATransDscrdStaleErrRsp | Number of times that an error response was discarded because it contained a valid correlation ID value but its originating server was not the last server to which the request was sent. | 30 min |
| CATransEndAbnorm | Number of reliable transactions that terminated abnormally. | 30 min |
| CATransEndAbnormRateAvg | Average rate per second that ComAgent transactions ended abnormally during the collection interval. | 30 min |
| CATransEndAbnormRateMax | Maximum rate per second that ComAgent transactions ended abnormally during the collection interval. | 30 min |
| CATransEndAnsErr | Number of reliable transactions initiated by local User Layers that ended with an error response from a destination server. | 30 min |
| CATransEndErr | Number of reliable transactions initiated by local User Layers that ended abnormally with an error response from a destination server. | 30 min |
| CATransEndNoResources | Number of reliable transactions initiated by local User Layers that ended abnormally due to lack of resources. | 30 min |
| CATransEndNoResponse | Number of reliable transactions initiated by local User Layers that ended abnormally due to a timeout waiting for a response. | 30 min |
| CATransEndUnkwnSvc | Number of reliable transactions initiated by local User Layers that ended abnormally because they referred to an unknown service. | 30 min |
| CATransEndUnregSvc | Number of reliable transactions initiated by local User Layers that ended abnormally because they referred to a known service that lacked a registered User Layer. | 30 min |
| CATransNoReTxMaxTTL | Number of reliable transactions abnormally ended because of Max Time to live exceeded without any retransmits. | 30 min |
| CATransRetx | Number of times stack events were retransmitted. | 30 min |
| CATransReTxExceeded | Number of reliable transactions abnormally ended because of Max number of Retries exceeded. | 30 min |
| CATransStaleSuccessRsp | Number of times that a success response was received from an unexpected server and was accepted to end a transaction. | 30 min |
| CATransTTLExceeded | Number of reliable transactions abnormally ended because of Max Time to live exceeded. | 30 min |
| CATxDscrdConnUnAvail | Number of User Data egress events discarded because connection was not in-service(down/blocked/not aligned). | 30 min |
| CATxDscrdDestUserIncmpat | Number of User Data egress events discarded because the remote doesn’t support requested capabilities (either it doesn’t support stack or event library or event library version is incompatible) | 30 min |
