Cloudera Navigator Auditing

Required Role:

An audit event is an event that describes an action that has been taken for a cluster, host, license, parcel, role, service or user.

Cloudera Manager records cluster, host, license, parcel, role, and service lifecycle events (activate, create, delete, deploy, download, install, start, stop, update, upgrade, and so on), user security-related events (add and delete user, login failed and succeeded), and provides an audit UI and API to view, filter, and export such events. For information on Cloudera Manager auditing features, see Lifecycle and Security Auditing.

The Cloudera Navigator Audit Server records service access events and the Cloudera Navigator Metadata Server provides an audit UI and API to view, filter, and export both service access events and the lifecycle and security events retrieved from Cloudera Manager.

Viewing Audit Events

  1. Start and log into the Cloudera Navigator data management component UI.
  2. Click the Audits tab. The Audit Events report displays all audit events that occurred during the last hour.

Filtering Audit Events

You filter audit events by specifying a time range or adding one or more filters containing an audit event field, operator, and value.

Specifying a Time Range

  1. Click the date-time range at the top right of the Audits tab.
  2. Do one of the following:
    • Click a Last n hours link.
    • Specify a custom range:
      1. Click Custom range.
      2. In the Selected Range endpoints, click each endpoint and specify a date and time in the date control fields.
        • Date - Click the down arrow to display a calendar and select a date, or click a field and click the spinner arrows or up and down arrow keys.
        • Time - Click the hour, minute, and AM/PM fields and click the spinner arrows or up and down arrow keys to specify the value.
        • Move between fields by clicking fields or by using the right and left arrow keys.
  3. Click Apply.

Adding a Filter

  1. Do one of the following:
    • Click the icon that displays next to a field when you hover in one of the event entries.
    • Click the Filters link. The Filters pane displays.
      1. Click Add New Filter to add a filter.
      2. Choose a field in the Select Property... drop-down list. You can search by fields such as username, service name, or operation. The fields vary depending on the service or role. The service name of the Navigator Metadata Server is Navigator.
      3. Choose an operator in the operator drop-down list.
      4. Type a field value in the value text field. To match a substring, use the like operator. For example, to see all the audit events for files created in the folder /user/joe/out, specify Source like /user/joe/out.
    A filter control with field, operation, and value fields is added to the list of filters.
  2. Click Apply. A field, operation, and value breadcrumb is added above the list of audit events and the list of events displays all events that match the filter criteria.

Removing a Filter

  1. Do one of the following:
    • Click the x next to the filter above the list of events. The list of events displays all events that match the filter criteria.
    • Click the Filters link. The Filters pane displays.
      1. Click the at the right of the filter.
      2. Click Apply. The filter is removed from above the list of audit event and the list of events displays all events that match the filter criteria.

Service Audit Event Fields

The following fields can appear in a service audit event:
Display Name Field Description
Additional Info additional_info JSON text that contains more details about an operation performed on entities in Navigator Metadata Server.
Allowed allowed Indicates whether the request to perform an operation failed or succeeded. A failure occurs if the user is not authorized to perform the action.
Collection Name collection_name The name of the affected Solr collection.
Database Name database_name For Sentry, Hive, and Impala, the name of the database on which the operation was performed.
