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.

System Dashboard

To access the system dashboard, click System System > System. You need to be logged in as admin to access the full feature set.

System Overview

The System Overview tab shows an overview of the collections and their states in the cluster. Click a specific collection to view the core name, collection name, Solr memory, system memory, and swap space usage.

API Insight

The API Insight tab shows the available REST API endpoints in the system.


The Configurations tab provides read access to all of the global property settings of the system. The UI allows you to filter the list of configuration items by terms and choose the node of the cluster to examine. If you need to change any configuration item, you should use the Configurations API.


The History tab shows the start and stop times of all services.

Heartbeat Data

The Heartbeat Data tab shows you the information that would be sent to Lucidworks as part of the System Usage Monitor, an optional program to report information about your system. You can enable or disable sending the data in this screen, by checking the box next to Report Heartbeat.


The Metrics tab provides access to the metrics indexed in the system_metrics collection, if enabled.

For details, see System Metrics.


The Threads tab shows the details of each active thread in the system. This is the same information returned by the threads endpoint of the System API.

Other System Menu Items

In addition to the System Dashboard, the System menu includes several tools for configuring and managing your Fusion deployment. Among them are the Messaging Services and Solr Clusters items.

Log viewer dashboards

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.

Messaging Services

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

Solr Clusters

The Solr Clusters menu provides controls for both reporting on and configuring Solr servers. When using Fusion with an existing Solr cluster, this provides a single point of access for both systems.
