Editing MinMax thresholds

The threshold must be created by the Add Threshold functionality or already be defined in the system before you can edit it.

To edit a MinMax threshold:

  1. Double-click the threshold in the list. The Edit Threshold dialog box appears.
    Figure 86. Edit Threshold ../images/thresholddefinition.png
  2. Enter or select values to define the threshold:
    • Name- Displays the value for the ID you entered on the Add a New Threshold dialog.
    • Description- Description of the threshold that you entered on the Add a New Threshold dialog. The description is included in each event that is created from this threshold.
    • Type- Type of threshold that you selected. You cannot change the type of threshold. If you want a different type of threshold, you need to create a new one and assign the correct type.
    • Explanation- Information field where a user can enter information about what the event means. This field is included in each event that is created from this threshold
    • Resolution- Information field where a user can enter information about what to do to resolve the event. This field is included in each event that is created from this threshold.
    • Data Points- Select one or more data points to which this threshold will apply and click the right-arrow button to move them to the selected column.
    • Severity- Select the severity level of the first event triggered when this threshold is breached.
    • Enabled- Select the check box to enable the threshold, or clear the check box to disable it.
    • Minimum Value- If this field contains a value, then each time one of the select data points falls below this value an event is triggered. This field may contain a number or a Python expression. When using a Python expression, the variable here references the device or component for which data is being collected. For example, a 90% threshold might be specified as:
      (here.linkSpeed or 1e10) /8 * .9
      The division by 8 is needed because interface speed frequently is reported in bits/second, where the performance data is bytes/second.
    • Maximum Value- If this field contains a value, then each time one of the selected data points goes above this value an event is triggered. This field may contain a number or a Python expression.
    • Event Class- Select the event class of the event that will be triggered when this threshold is breached.
    • Escalate Count- Enter the number of consecutive times this threshold can be broken before the event severity is escalated by one step. A value of zero (0) indicates that the severity will not escalate.
