Doing a story on the monitoring capabilities in EM12C
Being a member of the EM Development Team, Ana really knows the ins and outs especially on this subject.
Here my staccato notes
Administration Groups and Template Collections
Administration Groups actually is the automation Group management.
Template Collections relate to the Administration group and thereby define the monitoring settings that need to be deployed to the targets in the administration group.
Administration Groups are implemented in terms of a Hierarchy, like you might have an Administration group “ALL TARGETS” that subdivide in two groups “PRODUCTION” and “NON PRODUCTION”, which is actually based on the Lifecycle Phase of targets.
The targets themselves will be in the Leaf level nodes.
If any modification is made to any of the template settings the modification will be applied to the targets automatically.
This also means that if a new target is included in a Group, the monitoring settings are applied automatically.
New in EM12c 126.96.36.199 is the Dynamic Group that allows you to add targets to a group automatically based on criteria that are added to the group once it gets created.
A tip might be to designate an user with appropriate privileges to create dynamic groups on behalf of your team.
As you can only create 1 Administration Group hierarchy, Dynamic Groups come in very handy if targets need to be in multiple groups for instance to structure jobs, reports etc. You could than decide to use Administration Groups to monitoring only.
Best practice tips
- Consolidate groups to simplify group hierarchy
- Set the time zone when you define the group
- After hierarchy is create, you can:
- Add or remove values for target property criteria
- Add new/remove target property criteria
- Rename any group
- Target properties set on the cluster automatically applies to all members
Non-cluster aggregate targets
- Target property set on aggregate does not auto apply to members
You can now set properties values for an Enterprise Manager user.
Targets created by this user automatically apply the properties to the targets
- Cost centre
- Line of business
- Lifecycle Phase
There is an “Unassigned Targets” report in the EM reporting system
- Property values don’t match all membership criteria
Aggregates are not privilege propagating
To convert to use EMCLI
How do you find a group in a large hierarchy?
Use the search feature in the associations tab (new in 188.8.131.52)
Search by partial group name
How do I make sure every thing has been setup properly?
Enhance Group Management Settings (new in rel 2)
Se on Leaf groups
Shows parent groups/template collections
Metric extensions to replace User Defined Metrics
Custom metrics to monitor conditions specific to your environment
Deployment to targets
Export/import between EM sites
Manage by incidents that are made out of events (alerts)
Centralized incident management console to view manage, diagnose and resolve incidents from one location
Notification rules are replaced by Incident Rules Sets
Who should create these rules
Assign senior admin to create rules for the team
Grant “create enterprise rule set” and “operator any target” to administrator
Grant co-author access to other users as needed
