The rule library contains all of your rules. You can view and filter, create, edit, clone, and delete rules from the rule library. Rules are sort-able by type as well as by reference count. Reference count shows how many policies use the metric. Multiple monitor policies can reference a single rule. If a rule is edited, it is updated in all of the monitor policies that reference it.
To work with rules in the rule library
Create and delete rules
You can click the New option in the toolbar and then select a rule type to create.
See Types of rules.
You can also select a rule and click the Delete option in the toolbar to delete a rule. However, you cannot delete a rule that other rules or policies reference. Verify that a "0" is displayed in the Reference Count column of the rule library to make sure that a rule is not referenced.
Edit an existing rule
You can select a rule and then click the Edit option in the toolbar.
If you edit a rule that is referenced in a policy, the policy is updated to include the updated rule. If you do not want this behavior to occur, first create a clone of the rule and then edit the clone.
Clone and existing rule
You can select a rule and then click the Clone option in the toolbar. A clone of the rule is created in the library with Copy of prepended to the original name.
See Cloning rules.
View and Search for rules
You can type a search string in the Search field and press Enter to display only the rules that match your search criteria. You can also select a category type from the view drop-down menu to only display rules of a certain category.
