Viewing Nodes in the Fabric
The Fabric Monitoring inventory page allows the administrator to monitor each node in the Junos Space fabric. You can also monitor the status of the database, load balancer, and application logic functions running on each node, identify nodes that are overloaded or down, and view when the node was rebooted. The Fabric inventory page refreshes every 10 seconds, by default.
Changing Views
You can display fabric monitoring in tabular view. The fabric nodes appear in a table sorted by node name. Each fabric is a row in the Fabric Monitoring table.
To change views:
- Select Administration > Fabric. The Fabric page appears.
- Click a view indicator at the left of the title bar of the Fabric page.
