Chapter 18: Advanced Monitor Topics 227
The following examples show state transitions for a service monitor that
uses the default values for autorecovery, priority, and serial script
ordering. Start and Stop scripts are also defined for the monitor. The
virtual host associated with the monitor has a primary interface and two
backup interfaces.
The first example shows the state transitions that occur at startup from an
unknown state. At i1, all instances of the monitor have completed
stopping. At i2, the virtual host is configured on the Primary. At i3, the
monitor start script begins on the Primary and probing begins on the
backups. At i4, probing begins on the Primary.
