Viewing Nodes in the Fabric
You can 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. You can view nodes in the fabric either graphically or in a table.
Viewing Nodes as Graphics
You can view thumbnail, quick look, and detailed information about the nodes running on a fabric.
To view the nodes in a fabric:
- From the task ribbon, select the Administration workspace icon.
- From the task ribbon, select the Manage Fabric icon.
The Fabric Monitoring window displays the nodes in the fabric.
The Fabric Monitoring window is refreshed every 10 seconds, by default.
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, the following illustration shows the icons for a JA1500 Junos Space Appliance, that is running all node functions.
- To
view runtime and node function status for a node, click on the node.
Runtime and status information for the selected node is displayed in the Quick Look panel.
- To view detailed runtime and status information
for a node, double-click on the node.
For example, the following illustration shows the node icon and detailed information for a JA1500 Junos Space Appliance.
Viewing Nodes in a Table
To view configuration and runtime information in a table:
- From the task ribbon, select the Administration workspace icon.
- From the task ribbon, select the Manage Fabric icon.
- Click the table icon in the filter bar, as shown
in the following example.
Junos Space displays a table with information about each node in the fabric.
Table 1 describes the node information displayed in each field in the table and information available from the detailed view.
Table 1: Fields for the Fabric Monitoring Inventory Panel
Field
Description
Node Name
The logical name assigned to the node.
Note: For the first node, Junos Space uses the node name that the user specifies during the initial configuration of the Junos Space appliance (physical or virtual). For each subsequent node, the user must specify a node name when adding the node to the fabric.
Management IP
The IP address for the node.
Status
Connection status for the node.
- UP—Node is connected to the fabric.
- DOWN—Node is disconnected from the fabric.
% CPU
The percentage of CPU resource utilized by the node.
- Unknown—The percentage of CPU utilized is unknown, for example, because the node is not connected.
% RAM
The percentage of memory resource utilized by the node.
- Unknown—The percentage of memory utilized is unknown, for example, because the node is not connected.
% Disk
The percentage of
/vardirectory utilized by the node.- Unknown—The percentage of
/vardirectory utilized by the node is unknown, for example, because the node is not connected.
App Logic
Application Logic function status for the node.
- UP— Application Logic function is running on node.
- DOWN—Application Logic function enabled on the node but is not running.
- Unknown—Status for the application logic function is unknown, for example, because the node is not connected.
- N/A— Application Logic function is not configured to run on the node.
Database
Database function status for the node.
- UP—Database function is running on node.
- DOWN—Database function that is enabled on the node but is not running.
- Unknown—Status for the Database function is unknown, for example, because the node is not connected.
- N/A—Database function is not configured to run on
the node.
Note: By default, the Database function is enabled on no more than two nodes in the fabric.
Hardware Model
Model of Junos Space Appliance.
Note: Hardware model is displayed when you double-click a thumbnail or table row for a detailed view of the node.
Note: Hardware model only applies for a Junos Space physical appliance.
Load Balancer
Load Balancer function for the node.
- UP – Load Balancer function is running on the node.
- DOWN – Load Balancer function that is enabled on the node is not running.
- Unknown – Status for the Load Balancer function is unknown, for example, because the node might not be connected.
- N/A – Load Balancer function is not running because
it is not configured to run on the node.
Note: By default, the Load Balancer function is enabled on no more than two nodes in the fabric.
Serial Number
Serial Number for the Junos Space appliance.
Note: Serial number is displayed when you double-click a thumbnail or table row for a detailed view of the node.
Software Version
Junos Space Release Version.
Note: Software version is displayed when you double-click a thumbnail or table row for a detailed view of the node.
