File System Space Used

Select the File System Space Used entry from the Mass Storage list to display the name of each volume, the number of megabytes used by that volume out of the total available, the number of megabytes unused by that volume, the total number of megabytes available, and the percentage of total space used. If disk space thresholds are set for any of the volumes, they are represented by arrows at the top of the disk space usage bar graph.

Disk Space Usage Bar Graph

The bar graph uses a color code to indicate disk space status. The bar is blue if the disk space usage is at or below the warning and critical thresholds, or if no thresholds have been set for the volume. The bar is yellow if the disk space usage is above the warning threshold and below the critical threshold. The bar is red if the disk space usage is above the critical threshold. The unused space on the volume is displayed in gray.

Disk Space Usage Thresholds

The disk space usage threshold values are displayed inside triangular shaped indicators above the disk space usage bar graph. A yellow indicator is used for the warning threshold and a red indicator is used for the critical threshold. If the indicator is gray, then a threshold has not been created for this volume, or the threshold has been disabled.

Resetting and Saving Thresholds

If you have security access to create, modify, or delete thresholds, two buttons display at the end of the page:

If there is more than one volume, a Synchronize thresholds for all volumes checkbox displays. Select the checkbox to set all critical thresholds to the highest critical threshold value, and to set all  warning thresholds to the highest warning threshold value. If you change one threshold, the same threshold on all of the other volumes will automatically change to the same value.

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

  1. 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.

  2. Release the mouse button.

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

Modifying Thresholds

  1. To modify a threshold, select the 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.

  2. 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

  1. To delete a threshold, select the threshold indicator with the left mouse button, holding the button down and dragging the threshold indicator to the left until the indicator turns gray.

  2. When you save the thresholds, disabled thresholds are deleted.
