Monitoring Performance Alerts

Oracle Database includes a built-in alerts infrastructure to notify you of impending problems with the database. By default, Oracle Database enables the following alerts:

Tablespace Usage
Snapshot Too Old
Recovery Area Low on Free Space
Resumable Session Suspended

For information about alerts and how to manage them, see Monitoring and Tuning the Database.

In addition to these default alerts, you can use performance alerts to detect any unusual changes in database performance.
