KUserFeedback UUID question

[Aleksey Kontsevich]

Hi Volker,

Have some questions. I've read Telemetry discussion in kde-community mailing list, however some KUserFeedback logic is not quite clear: https://www.mail-archive.com/kde-community@kde.org/msg03898.html

You said data is submitted once per week to a server.  How the user is identified as I think the returned statistics contains data from previous sessions, but there is no user identification in KUserFeedback? 

We thought to add at least machine ID like Krita does. Identifying the user is important. If the frontend sends the data once a week, we still want to know, how design mode usage changes between the weeks. If developer has several installations in different hosts, it would be sufficient to know installation-specific statistics. 

Could You clarify our questions and concerns, please? Does returned statistics contain data from previous sessions or not? If aggregation performed only in analytics tool and server contains raw data how statistics integrity is provided? How data collected between submissions, does statistics contain data from previous submission or not? Does it makes sense to add some randomly generated machine ID on first connection to the server for satisfy our needs? Other thoughts?

Thanks in advance!
