Hi Group, Greetings. I am trying to setup OEM email alert when the tablespace reaches 85% for warning and 95% for critical. I go to preferences -> under Notification -> Rules -> create a rule -> for All targets of type Database Instance -> and the metric is Tablespace Space Used . I do not see any threshold specified (remember seeing thresholds specified). Am I doing it right? My OEM grid is 11.1. Dint get much help from google and metalink. Thanks in advance.
