Hello @Kausik
The Traffic Analysis gives the Applications / Website information for a client overall. But the dashboard does not store all the specific flows for all the websites visited. It only stores the flows that are visited in the past hour/day/week/month.
If you would like to track each flow and need specific timestamp with hour/second information, Syslog server should be way to go.
Let me know if you have any questions.

Meraki Team
