System Administration with the Fusion UI

The Fusion UI provides information for system administration and lets you configure system components.

The REST API provides equivalent functionality. See System Admin APIs.

DevOps Center

The DevOps Center is a tool for monitoring, troubleshooting, and incident investigation. It consists of an interactive log viewer, providing views into this Fusion cluster’s hosts and services using metrics and events.

Object Explorer

Object Explorer lets you easily find and manage Fusion objects within a specific app and across multiple apps in an entire Fusion deployment.

Log Viewer

Fusion includes some dashboards to view and analyze events in Fusion logs. You can also customize existing dashboards or create new ones. To access these dashboards, click System > Log Viewer. See Dashboards.

Access Control

Fusion provides application security by restricting access to known users. Users are assigned named sets of permissions which provide access to a specific function called roles. A Security Realm encapsulates a user database together with specific authentication and authorization mechanisms.

The Access Control panel allows you to view and edit users, roles, and security realms.


Fusion accepts large binary objects (blobs) for upload, and stores them in Solr. Blob uploads are used to install models, lookup lists, JDBC drivers, connectors, and more. In addition to the Blob Store API, the Fusion UI provides an interface to the blob store in the Fusion workspace.

Import Fusion Objects

You can use the Fusion UI and the Objects API to migrate collections and related objects, including your searchable data, configuration data, pipelines, aggregations, and other objects on which your collections depend. You can also migrate entire apps.

Messaging Services

The Messaging Services menu lets you configure system notifications, log messages, and alerts to external applications. Several messaging services are available.


A job is a runnable Fusion object that performs a specific activity. Datasource jobs, Spark jobs, and tasks are all types of jobs.

The Scheduler provides an interface for scheduling jobs.

Solr Config

Solr uses several XML configuration files to specify the contents and behavior of a Solr collection. Fusion provides a set of default configurations, but depending on your application needs, it may be necessary to edit these configuration files.

This Solr Config panel displays the set of Solr configuration XML files that you can edit. This is an advanced feature, for experienced Solr users. See the Solr wiki for more information on configuring Solr.
