Port Port blocked, Port connected, Port disconnected, Port created, Port deleted, Port link up, Port link down. Host Host joined or left the distributed vswitch. Host and vCenter Server configuration synchronized. Network Event Triggers VMware provides preconfigured alarms that trigger when events occur on networks. Table 21-16 lists the events you can use to trigger alarms on networks. Table 21-16.

Alarm Actions Alarm actions are operations that occur in response to triggered alarms. For example, email notifications are alarm actions. VMware provides a list of preconfigured actions you can associate with an alarm. These actions are specific to the object on which you set the alarm. For example, preconfigured alarm actions for hosts include rebooting the host and putting the host in maintenance mode. Alarm actions for virtual machines include powering on, powering off, and suspending the virtual machine. Although the actions are preconfigured, you must manually set up certain aspects of the action, such as having the action occur when a warning is triggered or when an alert is triggered, and whether to repeat the action. You can configure alarm actions to repeat in the following ways: n At a specified time interval after an alarm triggers. For example, if an alarm triggers because a physical host is not responding, you can have an email message sent every 10 minutes until the host is returned to a connected state or until the alarm trigger is suppressed. n Until the alarm is explicitly acknowledged by an administrator. When you acknowledge an alarm, the alarm actions are suppressed. The alarm trigger is not reset. It remains in its current state until the triggering condition, state, or event is no longer valid. Some alarm actions, such as sending notification emails or traps, and running a script, require additional configuration. NOTE The default VMware alarms do not have actions associated with them. You must manually associate actions with the default alarms. Default vSphere Alarm Actions VMware provides default alarm actions that you can associate with an alarm. When the alarm triggers, the action occurs. Table 21-17 lists the default vSphere alarm actions. VMware, Inc. 243
