Overview
The TCA-gen2 is docker based mS intended to replace TCA/cdap version, which was first delivered as part of ONAP R0. Functionality of TCA-gen2 is identical to that of TCA - where meaurement events are subscribed from DMAAP in VES structure, once events are recieved TCA-gen2 performs a comparison of an incoming performance metric(s) against both a high and low threshold defined and generates CL events when threshold are exceeded. When the original threshold defined are cleared, TCA-Gen2 will generate an ABATEMENT event to notify the downstream system on original problem being cleared.

To simulate the event flow and trigger missing tca-gen2 event, we can simulate a VES event into tca-gen2 subscription topic (using curl).
