Applies to:
Enterprise Manager Base Platform - Version 13.1.0.0.0 and laterInformation in this document applies to any platform.
Symptoms
Enterprise Manager (EM) 13c Cloud Control (13.1 or 13.2)
A host target (typically with an EM 13c Agent upgraded from 12c) either remains in DOWN status, or is UP but does not collect any metrics.
All the charts on the Host target's homepage show "No Data Available".
The EM Agent which is monitoring the host shows a target status of Up.
Database targets on this host show a target status of Up.
Stopping and starting the upgraded EM 13c Agent will return the Host target status to Up, but once the Host target is involved in a blackout, it is shown as Down when the blackout is over.
Changes
This issue is seen where an agent was upgraded from version 12c to 13c.
