Setting Thresholds on Dynamic Numeric Value Extractions

 Home  Previous  Next

Monitoring Studio enables you to set thresholds on Dynamic Numeric Value Extractions, that is Numeric Value Extractions performed on instances of a Dynamic Object.

Extracting numeric values can help you analyze the Dynamic Items output (the output of a command, a web page, the result of a SQL query, or WBEM query etc.). In order to apply this feature to all the Dynamic Items in a single operation, the Dynamic Object Builder creates Templates instances of the feature. While the standard Numeric Value Extraction feature apply to a single return output, Templates apply to all the Dynamic Items' output within the Dynamic Container.

To set or modify alert thresholds on Dynamic Numeric Value Extractions, right-click the Numeric Value Extraction (Template) > KM commands > Set thresholds and the threshold management wizard appears.

Step 1: Parameter Selection

Select the parameter on which you wish to apply the parameter and click Next.

NoteAn asterisk (*) displayed next to the parameter name signifies that the parameter already has thresholds.
NoteThe Reference Guide lists all the classes with details on the menu commands and the parameters available for each class.

Step 2: Dynamic Threshold Setting

Set the dynamic thresholds for the parameter previously selected. The available alert options are:

•Do not trigger any alert
•Trigger an INFORMATION
•Trigger a WARNING
•Trigger an ALARM

As for standard static thresholds, the following options are available:

•Border Alert: An alert can be triggered when the value polled is not between "x" and "y" and occurs "z" times in a row.
•Alert 1: An alert will be triggered if the value is between "x" and "y" and occurs "z" times in a row.
•Alert 2: An alert will be triggered if the value is between "x" and "y" and occurs "z" times in a row.

For each alert option, "x" and "y" may be the column number where the dynamic thresholds should be found –use the %{<Column Number>} syntax–, or a regular static numeric threshold. Both dynamic and static thresholds can be mixed.

ImportantSince Monitoring Studio applies thresholds as defined in the Threshold wizard and to avoid inconsistent alarms, make sure the Static and the Dynamic thresholds are in concordance with the values/columns of the extracted output.
ImportantDynamic Numeric Value Extractions can only be defined when the location of the numeric value in the Template is set to "in the column number "n""
