Select Reset to Original Values to return to the original threshold values, or the values from the last time the thresholds

were saved. This option also clears the Synchronize thresholds for all volumes checkbox so that thresholds can be set

individually.

Select Save Thresholds to save any thresholds that have been modified and delete any disabled thresholds.

Creating Thresholds

To create a threshold, select the gray threshold indicator with the left mouse button, holding the button down and

dragging the indicator to the right until you reach the appropriate value. The threshold value displayed in the

indicator changes as you are dragging. Release the mouse button.

Select Save Threshold to create the threshold with the displayed value.

Modifying Thresholds

To modify a threshold, select the threshold indicator with the left mouse button, holding the button down, and drag the

indicator to the right until you reach the appropriate value. The threshold value displayed in the indicator changes as

you are dragging. Release the mouse button.

NOTE: If the indicator moves below 6 percent, it changes to gray to indicate that it is disabled. When you

save the thresholds, disabled thresholds are deleted. A critical threshold can never go above 99 percent, or

lower than a warning threshold plus 3 percent. Therefore, if the warning threshold is 85 percent, the valid

range for the critical threshold is 88 percent to 99 percent. A warning threshold can never be higher than the

critical threshold minus 3 percent. Therefore if the critical threshold is 95 percent, the valid range for the

warning threshold is 6 percent to 92 percent.

Deleting Thresholds

To delete a threshold, select the threshold indicator with the left mouse button, holding the button down, and drag the

threshold indicator to the left until the indicator turns gray.

When you save the thresholds, disabled thresholds are deleted.

Logical Disk Space

• Volume—Name of the logical drive for which statistical information is gathered.

• Free Space (MB)—Unallocated space on the disk drive in megabytes. One megabyte equals 1,048,576 bytes.

• Free Space %—Ratio of the free space available on the logical disk unit to the total usable space provided by

the selected logical disk drive.

• Queue Length—Average number of both read and write requests that were queued for the selected disk during

the sample interval.

• Disk Busy Time % (Thresholds Supported)—Percentage of elapsed time that the selected disk drive is servicing

read or write requests.

Processors

• CPU—Name of the processor for which statistical information is gathered.

• Interrupts/sec—Average number of hardware interrupts the processor is receiving and servicing in each

second. It does not include Deferred Procedure Calls or DPCs, which are counted separately. This value is an

indirect indicator of the activity of devices that generate interrupts, such as the system clock, the mouse, disk

drivers, data communication lines, network interface cards, and other peripheral devices. These devices

normally interrupt the processor when they have completed a task or require attention. Normal thread execution

is suspended during interrupts. Most system clocks interrupt the processor every 10 ms, creating a background

of interrupt activity. This counter displays the difference between the values observed in the last two samples,

divided by the duration of the sample interval.

• % User CPU Time—Percentage of non-idle processor time spent in user mode. (User mode is a restricted

processing mode designed for applications, environment subsystems, and integral subsystems. The alternative,

privileged mode, is designed for OS components and allows direct access to hardware and all memory. The

OS switches application threads to privileged mode to access operating system services.) This counter displays

the average busy time as a percentage of the sample time.

• % Privileged CPU Time—Percentage of non-idle processor time spent in privileged mode. (Privileged mode is a

processing mode designed for operating system components and hardware-manipulating drivers. It allows direct

access to hardware and all memory. The alternative, user mode, is a restricted processing mode designed for

applications, environment subsystems, and integral subsystems. The operating system switches application

threads to privileged mode to access operating system services.) % Privileged CPU Time includes time servicing
