Rule View

A triggered rule is marked in the overview table with the color of the configured severity.

Remarks

  • The number of rules which can be activated concurrently is limited and depends on the selected plan size.
    To enhance the rule limit further "Rules Quota Upgrade" packages can be purchased in the Store. For latest information refer the IoT Value Plan product sheets or contact customer support.
  • In case the limit is exceeded you cannot create any further rule and will see the following warning message. Rules quota exceeded message
  • The rule engine triggers only in case of state changes. If values are still violated the rules are not triggered again.

Example

A rule has been created to monitor a value greater 90.
Now the value changes from 89 to 91 - means a state change happens - and the rule will be triggered and perform the configured actions.
Next the value changes from 91 to 100 - here no state change happens, due to the rule is already violated - and the rule won't be triggered again.

Roles

  • mdsp:core:tsm.full-access (for full access like create and delete)
  • mdsp:core:tsm.read-only (read only)

Snippets

Refresh the Rule View

The data model of the Rule View can be refreshed to get the latest list of rules, for example to update the view cyclically.

ruleViewComp.model.refresh();

Overwrite asset id in table headers with asset name

With the snippet below, you can format the table header and the columns, for example, to replace the asset id with an asset name or to show text in different languages.

      },
      value: function(value){
