Specifying thresholds

To add or change thresholds for data fields

1. Right-click the relevant column header (in tabular views) or field (in detail views) and select Edit thresholds.The Threshold dialog shows the column or field's currently assigned thresholds (if any).
2. Add a new threshold condition:
   1. Click the Insert button.The new threshold will be inserted after the currently selected row, or in the first row if no row is selected.
   2. Either copy threshold settings from another field by clicking the Inherit from check box and selecting that field, or select Condition and create a new condition.

   3. (optional) Use the Attr field to assign a color to a condition by specifying a numeric value from the list.

      Warning

      Note

      To change colors globally, use the Colors tab of the Properties dialog box.

   4. (optional) Specify an output character or character string that you want to substitute for field values that meet the specified threshold condition.For example, you might want the word CRITICAL to appear instead of actual data when the threshold condition is met.

3. (optional) Use the Move up and Move down buttons to rearrange the positions of the thresholds, or the Remove button to delete thresholds that you no longer need.Thresholds are evaluated in the order in which they appear.

   When you save your customized view, you can specify a location where you want your threshold conditions to be saved. The threshold can then be available to all instances of the same element in other views, or only for the view where the threshold is defined.

4. (optional) Click Apply to view the changes to the field without exiting the dialog.
5. When finished, click OK.
