24 Using Oracle Exalogic Elastic Cloud

Use Oracle Exalogic Elastic Cloud to discover and monitor instances of Exalogic Elastic Cloud (Middleware Machine). You can then display status information, including alerts and key performance metrics, of the following target types in an Exalogic Elastic Cloud:

• Application Deployments

• WebLogic Domains

• IB Switch - An IB Switch system has IB Switches as members. This is a one to many association. Each IB switch can have many IB Switch Ports as target components.

• Coherence Clusters

Exalogic Elastic Cloud (Middleware Machine) is modeled as a System target rather than a group target.

For more information about using Oracle Exalogic Elastic Cloud, see the following sections:

Using the Exalogic Elastic Cloud Discovery Wizard

You can use the Exalogic Elastic Cloud Discovery wizard to discover and monitor an exalogic target in Enterprise Manager.

One important prerequisite for discovery is that all the components running on the Exalogic Elastic Cloud must already exist in Enterprise Manager as targets. Exalogic Elastic Cloud discovery does not add or discover any of these targets. It simply identifies the targets present in the Exalogic Elastic Cloud and maps them to Enterprise Manager targets and then adds these Enterprise Manager targets as Exalogic Elastic Cloud system members.

To use the Exalogic Elastic Cloud Discover wizard, follow these steps:

1. Navigate to the Systems page.

2. From the Add drop-down menu, select Exalogic Elastic Cloud, then click Go.

   Enterprise Manager displays the Discover Exalogic Elastic Cloud page which allows you to enter the parameters and values required to discover an Oracle Exalogic target.

3. Specify a unique name for the Oracle Exalogic target you want to monitor in the Name field.

4. Select a Management Agent on one of the hosts in the Exalogic System to perform the discovery.

   If you choose a Management Agent that is not part of the Exalogic System, an error message appears stating that no Exalogic Property File can be found and indicating that you must choose a Management Agent which is on a Exalogic System Host.

5. Click Next. Enterprise Manager displays the Discover Oracle Exalogic Targets: Discovered Targets page. The page displays the Hosts that are discovered as part of the system.

6. Click Finish to complete discovery. You can also choose Back to return to the Discover Exalogic Elastic Cloud page or Cancel to terminate the discovery process.

   Enterprise Manager displays a confirmation that the Exalogic Elastic Cloud instance has been added and begins to monitor the Exalogic Elastic Cloud target. The new target is displayed on the Systems page.

Displaying and Using the Exalogic Elastic Cloud Home Page and Dashboard
