You can assign the actions that are taken when a policy is triggered, such as an email or SMS notification. Other types of actions do more than just notify. For example, a resource pool violation can trigger a script that increases the pool size.

Other common actions include restarting an application server if it crashes, purging a message queue that is blocked, or triggering the collection of transaction snapshots. You can also trigger a custom action to invoke third-party systems.

Because the definition of health rules is separate from the definition of actions, you can specify different actions for an event in different contexts, such as a threshold crossing in either a tier or node context. See Actions for more information about the different types of actions.
