Select Trace Route to trace the route from the monitor station to the device. Data is
collected in the RouteDetails table and the ServiceLevels table.
Note This is useful if you want to monitor bottlenecks or response times along the route.
h
Select the protocol used to contact the host from the Select Protocol drop-down list. We
recommend using ICMP because it is faster and less intrusive. Using UDP is slower, and the
Timeout must be at least 100 seconds.
