While monitoring templates are the preferred method for standardized threshold settings, you do have the
additional overhead involved in applying a template to different target types. In addition, if you change a metric in a
monitoring template, the template will have to be reapplied to its targets. Conversely, if metric threshold values are
changed for a specific target, the changes are not synchronized to the monitoring template.
EM12c provides template collections to help alleviate the manual effort of applying monitoring templates to
different target types. You can create template collections to group thresholds for targets of different types.
Administration Groups
Administration groups
allow you to easily automate the management and monitoring of targets by applying metrics,
compliance standards, and cloud policies to targets based on monitoring template collections. Members are
dynamically added to an administration group automatically, based on a set of defined global properties. Any target
that matches the criteria is added to the group, and template collections can be associated with those targets. As a best
practice, use administration groups for managing targets in Enterprise Manager.

administration groups are a wonderful, new feature in eM12c. however, you can assign only one notification
group per target, so this feature has some limitations. in some cases, you may want multiple notifications per target, and
for that you need the original enterprise Manager groups feature. For example, a target's monitoring requirement might
be to assign incidents to a production dBa group during business hours, and to generate e-mails to an on-call dBa group
after hours. this sort of complicated scenario can be satisfied only with the original enterprise Manager groups feature.
Tip
Planning the Hierarchy
Before administration groups are created, you should plan your administration group hierarchy. This hierarchy
comprises different, logically divided targets arranged in one or more levels based on global target properties. You
may also specify multiple target types that define an administration group.
It is important that the hierarchy be planned so that it is in line with your organization's operational and
monitoring standards. You should have an understanding of how targets are monitored so that similarly managed
targets are grouped together. For example, you may want to create a group for Production targets and another group
for Non-Production targets based on the
LifeCycle Status
property. In addition, you may want to create other levels in
the hierarchy that are subgroups of Production and Non-Production based on the following target properties:
•
Department
•
Line of business
•
Location
•
CSI number
•
Cost center
•
Contact
The decision of whether to create more levels in the hierarchy should depend on the monitoring characteristics
of the intended groups. For example, do you need to maintain separate metrics for HR and Sales groups, or can they
be monitored using similar metrics? The diagram shown in Figure
7-9
is an example of an administration group
hierarchy based on the LifeCycle Status, Location, and Line of Business target properties.
