Enterprise Manager for Oracle Database - Version to [Release 12.1]
Information in this document applies to any platform.


Note that this article describing how to exclude the TEMP and UNDO tablespaces from the Tablespace Used (%) metric is only applicable to Enterprise Manager, and

From Enterprise Manager onwards, the tablespace full metric is evaluated by the agent and the temp and undo tablespaces are not taken into account by default.  From onwards, there are separate metrics for temp and undo which need to be enabled.  These are called 'Tablespace Space Used (%) (Temp)' and 'Tablespace Space Used (%) (Undo)' respectively.  These will not be enabled by default.  For further information see:
