In this configuration we are monitoring real serial/ethernet links and frame-relay PVCs. The links between gw0 and up-pvc-data and up-pvc-h323 are PVCs carried over the serial link between gw0 and up. You can see in the screenshot an operational down interface.



Here you can see a sample history plot for the link between gw0 and up.



The configuration will look like:

menu ping xterm -e ping %h
menu traceroute xterm -e /usr/sbin/traceroute %h

#as we will get the load from the two user-defined polls,
#we disable the default load monitoring of this
