Following metrics are added for each event or group of messages processed in the
SPOE:
* processing time: the delay to process the event or the group. From the
stream point of view, it is the latency added by the SPOE
processing.
* request time : It is the encoding time. It includes ACLs processing, if
any. For fragmented frames, it is the sum of all fragments.
* queue time : the delay before the request gets out the sending queue. For
fragmented frames, it is the sum of all fragments.
* waiting time: the delay before the reponse is received. No fragmentation
supported here.
* response time: the delay to process the response. No fragmentation supported
here.
* total time: (unused for now). It is the sum of all events or groups
processed by the SPOE for a specific threads.
Log messages has been updated. Before, only errors was logged (status_code !=
0). Now every processing is logged, following this format:
SPOE: [AGENT] <TYPE:NAME> sid=STREAM-ID st=STATUC-CODE reqT/qT/wT/resT/pT
where:
AGENT is the agent name
TYPE is EVENT of GROUP
NAME is the event or the group name
STREAM-ID is an integer, the unique id of the stream
STATUS_CODE is the processing's status code
reqT/qT/wT/resT/pT are delays descrive above
For all these delays, -1 means the processing was interrupted before the end. So
-1 for the queue time means the request was never dequeued. For fragmented
frames it is harder to know when the interruption happened.
For now, messages are logged using the same logger than the backend of the
stream which initiated the request.
