Description: The elapsed time between the LANtern network monitor's issuance of the Ping and its receipt of the response. This data is passed with the pingNotification trap.

Note: There is a separate instance of this variable (indexed by the IP address of the host to receive the notification) for each ping outstanding. This is best illustrated by an example; suppose one wants to request the LANtern to ping host 130.57.1.2 and send the ping notification trap to host 130.57.8.9. Accordingly, a set request as follows has the desired effect: ipPingDuration.130.57.8.9 = 130.57.1.2
