HOW THRESHOLD LIMITS AND RESET VALUES WORK

When a parameter exceeds the threshold limit, an alert message appears in the AlertViewer. The

corresponding icons in the DataViewer and Operation Window turn red or yellow to show the

warning or abnormal alert status. (The default colors red, yellow, and green are assumed here.)

The alert status returns to normal when the parameter falls below the reset value. A recover message

appears in the AlertViewer, and the icons in the DataViewer and Operation Window return to green.

Most parameters have two limits (Fatal and Warning or Major and Minor) and a reset value for each

limit. When the parameter exceeds the Warning limit, a warning alert message (such as CPU Load

Warning) appears in the AlertViewer. The Agent's icon in the Operation Window and the appropriate

folder icon in the DataViewer turn yellow to indicate the warning status.

The warning status continues until it falls below the Warning Reset value, at which time the status

returns to normal. A warning recover message (such as CPU Warning Recover) appears in the

AlertViewer, and the icons in the DataViewer and Operation Window return to green.

The Fatal limit is similar. As the parameter increases and reaches the fatal limit, an error message

displays in the AlertViewer (such as CPU Load Error). Icons in the DataViewer and Operation

Window change to red to indicate the abnormal status.

When the parameter falls below the Fatal reset, the status is reset from Abnormal to Warning and an

Error Recover message displays in the AlertViewer. Icons change to yellow since the parameter still

exceeds the Warning limit. Status is normal when the value falls below the Warning reset value.
