Access OCNWDAF GUI Using CNC Console

8 Access OCNWDAF GUI Using CNC Console

This chapter describes how to configure different analytics parameters (global and service) and view analytics information in the Oracle Communications Networks Data Analytics Function (OCNWDAF) GUI. The OCNWDAF GUI is accessed using the CNC Console application. OCNWDAF provides a console interface using the highly secure GUI service, which allows you to use an interactive interface for performing various actions related to OCNWDAF services.

Support for Multicluster Deployment

CNC Console supports both single and multiple cluster deployments by facilitating OCNWDAF deployment in local and remote Kubernetes clusters. For more information about single and multiple cluster deployments, see Oracle Communications Cloud Native Configuration Console Installation, Upgrade, and Fault Recovery Guide.

A single instance of CNC Console can configure multiple clusters of OCNWDAF deployments, where each cluster has an agent console installation and a OCNWDAF installation.

CNC Console Interface

This section provides an overview of the Oracle Communications Cloud Native Configuration Console (CNCC), which includes an interface to configure the OCNWDAF features.

To configure the OCNWDAF services using the CNCC, log in to the CNCC application. To log into CNCC, update the hosts file available at the C:\Windows\System32\drivers\etc location when CNCC is hosted on a third party cloud native environment.

In the Windows system, open the hosts file in the notepad as an administrator and append the following set of lines at the end of the hosts file:

<CNCC Node IP> cncc-iam-ingress-gateway.cncc.svc.cluster.local
<CNCC Node IP> cncc-core-ingress-gateway.cncc.svc.cluster.local

For example:

10.75.212.88 cncc-iam-ingress-gateway.cncc.svc.cluster.local
10.75.212.88 cncc-core-ingress-gateway.cncc.svc.cluster.local

Note:

The IP Address mentioned above may change when the deployment cluster changes.

Save and close the hosts file.
Before logging into CNC Console, create a CNCC user name and password. Log in to the CNC Console application using these login credentials. For information on creating a CNC Console user and password, see Oracle Communications Cloud Native Configuration Console Installation, Upgrade, and Fault Recovery Guide.

8.1 OCNWDAF GUI Login

The OCNWDAF Graphical User Interface (GUI) can be accessed only after logging in to the CNC Console application. Before proceeding, ensure that the CNC Console is installed. For more information, see "Installing OCNWDAF GUI" section of Oracle Communications Networks Data Analytics Function Installation and Fault Recovery Guide.

Before logging in to the CNC Console application, create a username and password. For more information about username creation, see "Configuring CNC Console IAM" section in Cloud Native Configuration Console User Guide.

CNC Console Log in

Following is the procedure to log into CNC Console:

Open any web browser.
Enter the URL: http://<host name>:<port number>.
where, host name is cncc-iam-ingress-ip and port number is cncc-iam-ingressport.
Enter valid login credentials.
