Getting 'Tablespace Space Used %' alerts from OEM when plenty of free space is available for a tablespace considering the autoextend ON for datafiles.

For example:
From the output of dba_tablespace_usage_metrics, tablespace used_percentage is 80%.

Autoextend is ON for all the datafiles for USERS tablespace, so, alerts should not be triggered since the datafiles will autoextend if space is needed.
