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.
-In Amsterdam release, TCA was deployed into 7 node CDAP cluster. However since Beijin 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.

+Troubleshooting Steps
+=====================
+
+To support K8S deployment, TCA is packaged using CDAP SDK as base container. Deployment of TCA is done using cloudify blueprint which gets executed part of DCAE bootstrap container during ONAP/DCAE installation.
+
+The logs for TCA are accessible through CDAP GUI which is exposed on 11011/http. To enable external cluster access, a K8S nodeport is required.
+
+Prior to El-Alto release, 32010 nodeport was assigned by default to enable logs/validation. In El-Alto reason for security reasons, nodeport is no longer enabled by default under ONAP/DCAE deployment.
+
+
+Enable Nodeport
+---------------
+
+Following procedure can be used to enable nodeport for troubleshooting purpose.
+
+
+Update existing TCA service to change the service type from ClusterIP to NodePort by editing service definition
+ .. code-block:: bash
+
+ kubectl edit services -n onap dcae-tca-analytics
+
+* Change type from ClusterIP to NodePort
+* Set nodePort: 32010
+* Set externalTrafficPolicy: Cluster
+
+Once modified, save and exit. K8s will redeploy the TCA service and nodeport 32010 will be available for access.
+
+Following is an example
+
+Original service definition
+
+ .. code-block:: bash
+
+ spec:
+ clusterIP: 10.43.62.180
+ ports:
+ - name: port-t-11011
+ port: 11011
+ protocol: TCP
+ targetPort: 11011
+ selector:
+ app: dcae-tca-analytics
+ sessionAffinity: None
+ type: ClusterIP
+ status:
+ loadBalancer: {}
+
+
+Modified service definition to expose NodePort
+
+ .. code-block:: bash
+
+ spec:
+ clusterIP: 10.43.62.180
+ externalTrafficPolicy: Cluster
+ ports:
+ - name: port-t-11011
+ nodePort: 32010
+ port: 11011
+ protocol: TCP
+ targetPort: 11011
+ selector:
+ app: dcae-tca-analytics
+ sessionAffinity: None
+ type: NodePort
+ status:
+ loadBalancer: {}
+
+
+
+- Verify if updates done are reflected in K8S
+
+ .. code-block:: bash
+
+ kubectl get svc -n onap | grep dcae-tca-analytics
+ dcae-tca-analytics NodePort 10.43.62.180 <none> 11011:32010/TCP 83
+
+
+- CDAP GUI can now be accessed using **http://<k8snodeip>:32010**
+
+- Verify if following TCA process are in "RUNNING" state under **http://<k8snodeip>:32010/oldcdap/ns/cdap_tca_hi_lo/apps/dcae-tca/overview/programs**
+
+ * TCADMaaPMRPublisherWorker
+ * TCADMaaPMRSubscriberWorker
+ * TCAVESCollectorFlow
+
+
+- Under each process, logs can be viewed (or downloaded) by clicking on "Logs" tab
