Viewing Nodes in the Fabric

The Fabric Monitoring inventory page allows the administrator to view configuration and runtime information for 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, and identify nodes that are overloaded or down. The Fabric Monitoring inventory page refreshes every 10 seconds, by default.

For information about adding a fabric node, see Adding a Node to an Existing Fabric.

Changing Views

You can display fabric monitoring in two views: thumbnail and tabular. By default, fabric monitoring objects appear in thumbnail view.

In thumbnail view, fabric monitoring appears as icons listed in descending order alphabetically by node name. Each fabric has a node name.

Each node in the fabric is represented by a thumbnail, which indicates whether the node is a JA1500 Junos Space Appliance (JA1500) or a Junos Space Virtual Appliance (Junos Space VA), and the node functions (database, load balancer, or application logic) that run (whether up or down) on the appliance. For example, icons for the JA1500 Junos Space appliance and virtual appliance are shown.

In tabular view, fabric nodes appear in a table sorted by node name. Each fabric is a row in the Fabric Monitoring table.

To change views:

  1. Navigate to Platform > Administrator > Manage Fabric. The Manage Fabric page appears.
  2. Click a view indicator at the right of the Manage Fabric page title bar.

Viewing Fabric Node Details

To view detailed runtime and status information for a node:

  • Double-click a node in either thumbnail or tabular views.The View Node Details page appears.
