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
•Manage Profiles—See Managing Profiles
•Notification Settings—See Notification Settings
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 Notification Settings 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.
Procedure
Step 1 Select Faults > Display Faults. The Fault window appears.
Step 2 Use the Filter: bar to display the faults you want to view:

Managing Profiles
Every device managed by the WLSE has a profile assigned to it. A profile is made up of threshold values and policy settings.
If you have not assigned a specific profile to a device it has the system Default profile. The default profile can be edited, but it cannot be deleted.
The topics covered in this section are:
•Creating a Profile
•Copying a Profile
•Renaming a Profile
•Editing a Profile
•Deleting a Profile
•Assigning a Profile to a Device
•Viewing Devices
