The type of collect mode. Options: 1.collectMethodUnconfiged(-1) - Collect method is not configured. 2.adHoc(1) - Ad-hoc Session: Per request (from a Collector), the Exporter creates a session and closes it when either the data is streamed or a closing command is generated.Once Collector starts flow CMTS Exporter SHOULD start session, stream data and stop session. The CMTS Exporter can optionally support additional management interface triggers for starting the session. 3.event(2) - Event Based Session: It consists of an open-ended session or a Time Interval Session. During the time the IPDR session is open the exporter can stream records at any time, thus the name Event Based Session. In the case of an open-ended session, the collector could create documents based on size, number of records received, timestamps (to simulate Time Interval Sessions), or never creates an IPDRDoc. 4.timeInterval(3) - Time Interval Session: The exporter follows a schedule based session to stream data on a periodic time interval. The collector creates the IPDRDoc within those demarcation points. Note that the Time Interval Session is managed by the exporter as being delimited by session start/stop messages. A collector initiated flow operation is possible as well; the collector issues Flow Stop messages to stop the exporter streaming. Finally, it is possible to control the Time Interval Session at either end-points. A Time Interval Session may close immediately after the exporter streams the records or remain open until the end of the time interval in which case, the exporter stops the session and starts a new session for the next time interval.
