5 Threshold Crossing Analytics (TCA)
6 ==================================
12 The TCA (cdap-tca-hi-lo) app was first delivered as part of ONAP R0. In that release, it was intended to be an application that established a software architecture for building CDAP applications that demonstrate sufficient unit test coverage and reusable libraries for ingesting DMaaP MR feeds formatted according to the VES standard. Functionally, it 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.
14 In Amsterdam release, TCA was deployed into 7 node CDAP cluster. However since Beijing release as ONAP required application to be containerized and deployable into K8s, a wrapper TCA CDAP container was built using CDAP SDK base image on which TCA application is deployed.
