Hi @paul1923,
Traffic analytics can report specific hostnames once enabled on each network underNetwork-wide > General and set "Hostname Visibility" to "Report specific hostnames".
This feature allows you to show traffic for two hours, one day, one week and up to one month and can be exported to a csv file.
Here you can find more information > https://documentation.meraki.com/MS/Monitoring_and_Reporting/Switch_Traffic_Analytics
