Traffic logs are accessible from the Traffic tab in the Store dashboard.
The Traffic tab shows the last visits to your store. Of each visit the date, time, URL, browser, and operating system are shown. When a visit is clicked more information will be shown like status code and user agent.
The results can be filtered by either Request ID or Status Code by using the filter options on top of the list.
If you want to see the visits come in as they occur on the website you can press the Play button. This will enable Real-Time mode.
