Alert on custom properties

The following example creates multiple alerts using the NodeLocation custom property defined in Creating a Custom Property. An alert triggers when a node goes down. Upon triggering, the alert will write to a local log file, send a syslog message, and send an SNMP trap.

The ${variable} syntax is required for variables. For more information on the use of variables, see Variables and examples.
