Creating the rule and targeting the computer group
We cannot directly Target the custom group while creating the rule.
If we want to target the custom group to any rule then we have to First target any built in groups at the time of creating the rule and disable the rule. Then set the override for the custom group.
Regarding the editing the rule, the user must have permission on the built in group that we have selected in the beginning and the customer group.
The permission can be given from Administrator console\user roles
1. Create your group and add the members you wish to monitor.
2. Create your rule/monitor and target it at a suitable class. For example if the machines you wish to monitor are all SQL servers, you can use the SQL Computers class.
3. Ensure the rule/monitor is disabled by default. To do this, click the General tab in the Properties dialog box for the rule or for the monitor in question, then make sure that the Rule is Enabled check box is cleared (not checked).
