When working with Liongard's Meraki inspector, you may encounter instances where the "Daily Traffic" data is missing. This issue typically arises due to specific settings on your Meraki device not being enabled.
Understanding the Error
During an inspection, you might see the following error in the inspection log:
"Traffic Analysis with Hostname Visibility must be enabled on this network to retrieve traffic data."
This error indicates that the necessary settings to collect traffic data are not active on your Meraki network device.
