Foglight for Active Directory rules

Foglight for Active Directory includes a number of predefined rules to monitor all critical components of Active Directory® on a continuous basis to ensure that the directory is functioning properly. The rules included in this cartridge alert you to key conditions that may affect the health of Active Directory. Foglight allows you to modify these predefined rules or create your own rules to ensure you are monitoring statistics and alerting on conditions specific to your Active Directory environment.

Foglight for Active Directory provides an additional dashboard that can be used to manage the cartridge’s rules. That is, Foglight for Active Directory rules can be managed using one of the following dashboards:

•

Rules dashboard (Dashboards > Administration > Rules >All)

•

Active Directory Rule Management dashboard (Dashboards > Active Directory > Rule Management)


	NOTE: All original rules in each cartridge are reset when the cartridge is upgraded; therefore if you applied custom conditions to any original rules these modifications will be lost. It is recommended that when modifying rules you make a copy of the original, disable the original and enable the copy with the new condition. Use the copy rule icon to the far right of a rule on the Manage Rules dashboard to copy a rule.

This section describes the Active Directory Rule Management dashboard and explains the tasks that can be performed from this dashboard:

Rules dashboard

The Rules dashboard lists all rules that exist in your environment and allows you to drill down to rule definitions. From this dashboard you can copy, edit, and remove Foglight rules.


	NOTE: Predefined rules may be modified during regular software updates. To avoid losing changes to these rules, we recommend copying a rule and making edits to the copy. Enable the copy and disable the original rule. You may want to identify your custom rules with a unique prefix to make them easy to find.

To review and edit rules:

In the navigation panel, under Homes, click Administration.

In the Administration dashboard, click Rules > All.

The Rules dashboard opens.

From the Cartridge list, select Active-Directory.

The dashboard refreshes to display only the Foglight for Active Directory rules.

From here, you can perform the following tasks:

•

Review a short description of the rule.

•

Review and edit threshold values.


	TIP: For rules that reference registry variables for threshold values, modify the threshold in the registry variable, rather than modifying the rule. For help finding and editing registry variables, search for “Registry Variable” in the online help.

•

Copy rules.

•

Edit rule conditions.

•

Associate actions with rules.

•

Create user-defined rules.

For help with these tasks, open the online help from the Rules dashboard.

Active Directory Rule Management dashboard

The Active Directory Rule Management dashboard contains a sortable list of all the conditional severity rules used by Foglight for Active Directory. From this dashboard you can quickly see which conditional rules are enabled/disabled, the states (fatal, critical or warning) with active conditions, predefined alarm threshold values, rules with current alarms, and a brief description of each rule.


	NOTE: The Rule Management dashboard does not display simple rules that do not have user-definable conditions defining when to raise an alarm. To edit the simple rules, use the Manage Rules dashboard.
