We are looking at a device and its interface information and seeing gaps in the chart data.
When the DC requests a SNMP GET-NEXT for 220.127.116.11.18.104.22.168.1.16, 22.214.171.124.126.96.36.199.1.1.14 returns as the next result
This is due to the device being set to use SNMPv1 and one of the limitations for SNMPv1 is the inability to work with 64bit items.

Access the device in Monitored Devices and change the SNMP-GET version from SNMPv1 to SNMPv2c. Then either prompt an Interface metric family update or wait for change detection to occur the following morning.
