3 Discovering Hosts and Software Deployments

Discovery is the first step toward monitoring and managing the health of your software deployments. Discovery refers to the process of identifying unmanaged hosts and their software deployments, and adding them as manageable targets in Oracle Enterprise Manager Cloud Control (Cloud Control).

This chapter describes how you can discover the hosts and their software deployments, and add them to Cloud Control. In particular, this chapter describes the following:

3.1 Discovering Hosts and Targets Automatically

Automatic discovery refers to the process of scanning hosts for Oracle software that can be managed and monitored by Cloud Control. By default, the automatic discovery runs every 24 hours to discover targets.

In automatic discovery, you enable a Management Agent running on the host to run an Enterprise Manager job that scans for unmanaged hosts. You then convert these unmanaged hosts to managed hosts by deploying Management Agents on these hosts, then you search for targets on these managed hosts, and finally you promote these targets to managed target status.

You can configure automatic discovery to set up a schedule for discovery, the target types to be discovered, and the hosts to scan for targets. You can then promote the discovered hosts and convert them to managed targets in Cloud Control. You can also regularly identify targets that have been newly added to the infrastructure, and add them to Cloud Control for monitoring.

Once automatic discovery has been configured, you can check the Auto Discovery Results page on a regular basis to see what targets have been discovered.

For information on automatically discovering and monitoring targets, refer to the chapter Discovering and Monitoring Targets in the Oracle Enterprise Manager Cloud Control Administrator's Guide.

3.2 Discovering Hosts and Targets Manually

In addition to automatic discovery, Cloud Control enables you to manually add hosts as well as a wide variety of Oracle software and components as managed targets. When you add a target manually, you do not need to go through the process of discovery by adding the target directly. Discovering targets in this way eliminates the need to consume resources on the Oracle Management Agent to perform discovery when it is not needed.

For information on manually discovering and monitoring targets, refer to the chapter Discovering and Monitoring Targets in the Oracle Enterprise Manager Cloud Control Administrator's Guide.
