Traffic 64 service

The Traffic 64 service monitors the bandwidth consumption of a switch port or NIC. This service uses 64-bit SNMP values to calculate bandwidth consumption, which makes it more appropriate for monitoring high-throughput interfaces.

  1. Configure SNMP on the device. For more information, see the manufacturer's documentation.
  2. Login to N-able N-central.
  3. Click View > All Devices and click the name of a device.
  4. Click Settings > Properties and ensure the Use SNMP.
  5. Click Save if required.
  6. Click MonitoringStatus and click Add,
  7. Enter 1 for the number of instances of the Traffic 64 service that you would like to associate to the device
  8. Click Apply.
  9. Click the Traffic 64 service and click the Service Details tab.
  10. In Interfaces to Monitor, select the NICs/ports that you would like to monitor.
  11. Click OK.
