What it is and where to find it: Data summarizes traffic the app can observe. Open Data and check which item is being measured and which views are available. If the app offers views by server or by app, the server view helps show how traffic is distributed across servers; the app view helps identify traffic generated by apps. Upload and download figures measure data volume—not latency—and do not directly indicate connection quality.
How to use it: Note the statistics scope and readings before testing, make one specific request, then return to see what changed. To investigate a rule, consider Data alongside the current Global Routing mode, selected server, and connection logs. Background activity on the device may also generate traffic, so do not attribute every increase during a test to the page you just opened.
Keep in mind: A single page visit often involves multiple domains and connections, so an increase in a server’s traffic is only a clue; it cannot prove by itself that every request used the same policy. Different views, reporting periods, or resets can make readings from two checks incomparable. Data is not the service provider’s billing record. To explain a discrepancy, first align the reporting period and scope.
