Information in this document applies to any platform.
Database instance status metric error in Enterprise Manager 12c

Symptoms

The database instance target shows in status "Metric Collection Error" in Cloud Control 12c (12.1.0.2), or the database target shows firstly at 'status pending' for a period of time (could be up to two hours), and then changes to "Metric Collection Error".  

From the database homepage itself, in the "incidents and problems" section, the following can be seen:-

Metric evaluation error start - Error occurred while deploying AGENT plug-in: java.security.PrivilegedActionException: oracle.sysman.emSDK.agent.client.exception.PerformOperationException: Error while streaming JobReader:java.io.IOException: Broken pipe

 
Checking from database home page/monitoring/all metrics/
highlight: Response

Error:
the oracle_database target '<targetname>' does not exist
oracle.sysman.emSDK.emd.comm.NoSuchTargetException: the oracle_database target "<targetname>" does not exist

 

Note that if the metric collection error is over a month old, the underlying message may no longer show on the database home page itself.

In this case:-

go to:- 

database home page/oracle database/monitoring/metric collection errors
Shows Metric "Response", the error triggered date, the error type "collection failure" and the message:-

eg.

Metric evaluation error start - Error occurred while deploying AGENT plug-in: java.security.PrivilegedActionException: oracle.sysman.emSDK.agent.client.exception.PerformOperationException: Error while streaming JobReader:java.io.IOException: Broken pipe

 Or
