Use the Dashboard page to:
✔ Select a node
✔ See which nodes are on and which are off
✔ See if an alarm condition exists on any node
If an alarm condition exists, you can click the alarm light to view a 
description of the alarm and resolve it.
✔ See the number (cumulative to date) of objects served to users from each 
node
✔ See the traffic load (as current transactions per second)
The meter dial shows you how hard a node is working. When the needle is to 
the left on the dial, the work load is light. When the needle is to the far right 
(red), the node is overloaded.
Dashboard alert lights
The Dashboard contains two alert lights: an on/off light and an alarm light. Alert 
lights indicate the following about a node:
Resolving alarms
Alarms alert you to problems or warn you of potential problems. Alarm 
conditions themselves are built into the appliance—you cannot change them.
If an alarm light is on, you can click it to view a description of the alarm 
conditions. Click the Resolve button to acknowledge that you have been 
informed of the condition. 
    Important
Clicking the Resolve button only dismisses alarm messages; it does not actually 
resolve the cause of the alarms.
