Fault Monitoring


The Faults tab displays information to help you monitor your devices. All the device information shown under this tab is polled from the devices in your network.

Following are the subtabs under Faults:


Note Some of the subtabs may not be visible to some users.


Display Faults—See Displaying Faults

Specify Fault Thresholds—See Specifying Fault Thresholds

Specify Policies—See Specifying Policies

Fault Forwarding—See Forwarding Faults

Displaying Faults

This window displays device fault information. A fault is an abnormal condition that occurs when a system component exceeds a performance threshold or is not functioning properly. (See Specifying Fault Thresholds to set threshold levels.)

A fault can also occur when a system policy is violated. (See Specifying Policies to set policies.)

Displayed fault information is retained by default for 30 days. To change the default, see Managing System Parameters.


Note Your login determines whether you can use this option.
