• Device. The network device.
• Interface. The network interface.
• Packets Sent. The total number of packets sent throughout the current group during the selected time period.
• Packets Lost. The total number of packets lost throughout the current group during the selected time period.
• Percent Packet Loss. A percentage of packet loss throughout the current group for the selected time period.
• Total Poll Time (minutes). Amount of total time (in minutes) that passed during the time period selected..
• Time Unavailable (minutes). Amount of total time (in minutes) that a device was unavailable in the group.
• Percent Available. The total availability percentage averaged over all samples during the selected time period.

The Device Data table displays the same information as above, but on a per device basis.

Note: The Percent Available is a weighted average of availability for all data entries. It is not a simple average of percent availability for each entry.  The value for the total availability percentage is reached by:  multiplying the availability percentage with the amount of time that passed between polls to get a sum for each entry. Add those sums and divide by the sum of all time periods between polls.
