How to manage OEM monitoring template using administration group

 

Problem statement:Suppose you are upgrading your OEM version from 13.4 to 13.5 or higher.During this upgrade you are also changing your OS platform from SOLARIS to Linux.Since this is a change of platform so we need to install new OMS instance along with repository database.After that we need to add targets either manually or through auto discovery option of OEM.Now, real problem is everytime we add targets we need to apply corresponding monitoring template.This will be really time consuming tasks if you have thousands of non-host targets.This problem can be solved using administration group

This document will guide you how to make this tasks simple and reduces effort.

 

This has been tested in following environments

 

Source	Target
OMS:-13.4	OMS:- 13.5
Agent: -13.4	Agent :-13.5
Repository database:-19.6	Repository database:-19.26
OS:-Solaris 10	OS:- OEL 8

 

Please follow below steps

1.       First create monitoring templates and define metric threshold according to your environment.

I have created 2 simple monitoring templates,one of database instance and other for host.

If you don’t know how to create template use below reference.

Reference:- Using Monitoring Templates

2.       Follow below navigation in OEM console

Setup>Add Targets>Adminstration Groups

You will end up landing in Getting started tab.Click on Hierarchy tab and follow next step

3.       There are different ways you can create hierarchy levels but I found that creating  hierarchy

based on Target Type is simple.Any other attributes needs to be added in target properties.

               Once you select Target Type you will get below warning saying only 10 targets can be selected

 

You can see 10 different targets type appeared by default.

 

Remove and add targets based on your environment.

Now create the group using Create button on top right.You will get a confirmation message

Now you can see targets are automatically added in corresponding hierarchy groups

4.       Now click on Template Collections tab and click on create button.Basically we will add various templates under this like below

 

  Now save the template collections.

 5.       Now Go to association tab where we will associate group with template collections.Click on each group and then associate like below

6.        

Now you can see templates are associated with administration group

7.       Final step is to synchronize this template collection changes to all groups

Go to Targets>Groups and select Adminstration group.

Group page will open and then click on start syncronization

You will see how many targets are synchronized.

 

You are done with all steps.Everytime you add a target it will be automatically assigned to administration group and corresponding templates will be applied based on synchronization schedule.

Hope you have learnt something useful…
