the right frame.
Note that the above example is very basic and does not handle all possible event combinations. In particular:
• No action is taken when one of the hot spares becomes unavailable while the first server is passing traffic.
These will be indicated as down in the Cluster and Server tabs.
• No action is taken if the third server is not available. This could be handled by a separate event.
• No action is taken if all three servers are not available. This is best handled by a Responder combined with
a Match Rule.

Rebooting an Unresponsive Virtual Machine (VLB only)

In this example, we want to reboot a particular virtual machine running under VMware when the machine has been
unresponsive for 15 minutes.
To do this, we create two events to power up and power down the machine, and a third event that acts as a timer for
the power down and power up events.
If the server is not running, power the server down; otherwise, do nothing.
Event 1:
If the server is not powered on, power the server on; otherwise, do nothing.
Event 2:
If the server is running, block Event 1 and Event 2 for 15 minutes; otherwise, do nothing.
Event 3:
