About CPS Central

Central Overview

CPS Central is a consolidated GUI platform that enables users to perform Policy Builder (PB) configurations, manage custom reference table data, and launch the following CPS web-based applications and utilities:

  • Policy Builder

  • Custom Reference Data

  • Operations

    • User Interfaces

    • API Information

Central Architecture

The CPS Central system is built using the following major frameworks:

  1. Webpack

  2. Babel

  3. vue.js

  4. Node Package Manager

  5. Bootstrap

The following section describes the components of CPS Central:
  • PB API: Processes HTTP requests and contains the following two API sets :

    • Utilizes the existing PB service API for user login authentication, multi-repositories, and publish operations.

    • Serves as a proxy layer to interface with CRD-API and to support CRD data management.

    While the PB API is composed of the two API sets described above, both are accessible from the CPS Central interface.

  • PB Servlet: Supports PB embedded screens to provide the existing Policy Builder parity functions. Both PB basic and advanced operations are supported.

  • Client GUI: CPS Central GUI where the major component is decomposed into various modules and sub-components to support CPS Central GUI.

The hostname is displayed in the login dialog box and system banner to differentiate between open windows while performing any operation of the CPS system. It indicates which system is being modified and prevents any errors or misconfigurations.

The hostname is displayed when the parameter -Dhostname=lab is configured in pb/qns.conf files. If it is not configured in the qns.conf file, it is displayed as a result of the command "hostname" on the server.

The hostname is displayed in the login panel only when the following argument is set to true:

-DshowSitenameLogin
