Solaris Event Tests

The Oracle Enterprise Manager Advanced Event Tests for Solaris are divided into a series of classes or groupings that will enable you to find the event test you are interested in registering.

The class names and some of the events that you can register within the classes are listed as follows.

The following tables list the Solaris event tests by class. The full descriptions of the individual event tests follow the tables. The event tests are in alphabetical order.
