Cloudera Navigator Console

The Cloudera Navigator console is the web-based user interface that provides data stewards, compliance groups, auditing teams, data engineers, and other business users access to Cloudera Navigator auditing, metadata, lineage, analytics, and other capabilities.

For example, compliance teams use the Cloudera Navigator console to view audit event reports, save reports for offline use (such as providing documented audit trails to bank auditors), and identify logon attempts by unauthorized users. Data stewards use the Cloudera Navigator console to define managed metadata models that apply to the various use cases in their organizations, define policies that apply the metadata as needed upon ingestion into the cluster, and allow other users to trace the lineage of data that has been transformed over its lifetime in the cluster, back to its source (provenance).

The Cloudera Navigator console provides a unified view of auditing, lineage, and other data management capabilities across all clusters managed by a given Cloudera Manager instance. That is, if the Cloudera Manager instance manages five clusters, the Cloudera Navigator console can gather audit events for all five clusters, as well as manage metadata and display lineage diagrams that allow tracking data sources through any number of transformations to any end result across the five clusters.

Note: The Cloudera Navigator console invokes the REST APIs exposed by the web service on the host supporting the Navigator Metadata Server role instance. The APIs can be called directly by in-house, third-party, and other developers who want to automate tasks or implement functionality not currently provided by the Cloudera Navigator console. See Cloudera Navigator APIs for an overview and other details.

Assuming that the Cloudera Navigator data management component is running, that you have a login account for Cloudera Navigator, and that you know the host name and port of Navigator Metadata Server role (or have been given this information by your system administrator), follow the steps below to access the Cloudera Navigator console.

Accessing the Cloudera Navigator Console

The Cloudera Navigator console can be accessed from the Cloudera Manager Admin Console or directly on the Navigator Metadata Server instance. Only Cloudera Manager users with the role of Navigator Administrator (or Full Administrator) can access Cloudera Navigator console from the Cloudera Manager Admin Console.

From the Cloudera Manager Admin Console:

Open your browser.
Navigate to the Cloudera Manager Admin Console.
Log in as either Navigator Administrator or Full Administrator.
From the menu, select Clusters > Cluster-n.
Select Cloudera Navigator from the menu.
Log in to the Cloudera Navigator console.

To access the Cloudera Navigator console directly:

Open your browser.
Navigate to the host within the cluster running the Cloudera Navigator Metadata Server role.
```
http://fqdn-1.example.com:7187/login.html
```
In this example, node 1 of the cluster is running the Navigator Metadata Server role, hosted on the default port 7187. The login page displays.
Log in to the Cloudera Navigator console using the credentials assigned by your administrator.

If your Cloudera Navigator instance has been configured to integrate with your organization's Active Directory (or other LDAP instance) for authentication, your credentials may be simply the same user account and password you use every day for your other production systems.

Menu and Icon Overview

The Cloudera Navigator console opens to an empty Search results page and displays the following menu.

The user_name (the account that is logged in to Cloudera Navigator) and question mark icon (see the table) always display. However, other available menu choices depend on the Cloudera Navigator user role of the logged in account. In this example, the admin account is logged in.

This table provides a reference to all menu choices.

Icon or menu	Description
Search	Displays sets of filters that can be applied to find specific entities by source type, type, owner, cluster name, and tags.
Audits	Displays summary list of current audit events for the selected filter. Define filters for audit events, create reports based on selected time frames and filters, export selected audit details as CSV or JSON files.
Analytics	Menu for HDFS Analytics and Data Stewardship Analytics selections. This is your entry point for several dashboards that display the overall state of cluster data and usage trends: Data Stewardship Analytics displays Dashboard and Data Explorer tabs. HDFS Analytics displays Metadata and Audit tabs.
Policies	Displays a list of existing policies and enables you to create new policies.
Administration	Displays tabs for Managed Metadata, Role Management, and Purge schedule settings.
`user_name`	Displays account (admin, for example) currently logged in to Cloudera Navigator. Menu for Command Actions, My Roles, Enable Debug Mode, and Logout selections.
	Help icon and menu. Provides access to Help, API Documentation, and About selections. Select Help to display Cloudera Navigator documentation. Select About to display version information.

Menu selections available for any specific login session depend on the privileges that have been granted to the account holder, through their assigned user role. In other words, a user with the Navigator Administrator user role has all menu selections and functions available, while a user with the Auditing Viewer user role can only access the Audits menu to view, report on, and analyze audit events gathered by the system.
