Host Target not discovered

Question

Hi,
We have reinstalled the OEM agent in an existing host. However, when we monitor from GC UI console we do not find the host name under the list of targets in target hosts page.
We can see that the agent has been discovered in the target agents home page. The agent has discovered the targets in the target host box. We can find the list of hosts in the targets.xml file. However, none of the targets discovered by the agent is visible in the targets page in GC UI console, also emctl agent config listtargets , also shows the list of targets discovered by the agent on the target host.
Not sure why the targets that are being discovered by agent are not being displayed in GC UI console.
Regards,
Rup

By default, the Add Host Targets Wizard configures only the following types of plug-ins:
◦All discovery plug-ins that were configured with the OMS from where the Management Agent software is being deployed.
◦Oracle Home discovery plug-in
Oracle Home monitoring plug-in
By default, the host and the Management Agent get automatically added to the Enterprise Manager Cloud Control console for monitoring. None of the targets running on that host get automatically discovered and monitored.
To monitor the other targets, you need to add them to Enterprise Manager Cloud Control either using the Auto Discovery Results page, the Add Targets Manually page, or the discovery wizards offered for the targets you want to monitor.
For information about discovering targets in Enterprise Manager Cloud Control, refer to the chapter on adding targets in the Administrator's Guide: http://docs.oracle.com/cd/E24628_01/doc.121/e24473/toc.htm
