Platform Team/Usage Statistics

Summary

Sugar usage statistics might be very useful from, e.g., an educational or research point of view. Statistics might be anonymous or personalized (by taking special efforts to keep information secure and local only for a particular deployment).

Statistics

All types of statistics are identified by IDs in a dot separated hierarchy. This makes it possible to refer to the particular type or level of data.

• shell
  Shell related stats.
  • shell.run
    Shell process is run.
  • shell.active
    Shell or activity window is active.
  • shell.collab
    Collaboration related stats in Shell.
    • shell.collab.buddies
      Number of buddies in the Neighborhood view.
• activity
  Activities related stats; specified only for the particular activity.
  • activity.run
    Activity is run.
  • activity.active
    Activity window is active.
  • activity.collab
    Collaboration related stats for activities.
    • activity.collab.buddies
      Number of buddies activity is interacting with.
• system
  System related stats.
  • system.uptime
    System uptime value.

Implementation

Monitor

The usage statistics will be gathered by sniffing DBus messages in the sugar-client program launched with the monitor command. The sugar-client will stay in daemon mode, and send collected and filtered data to the sugar-server.

Journal crawler

In addition to the realtime monitoring, it might be useful to collect some stats from the Journal. It should be possible to run this code on a client side, or, on school servers using Journals backups.

This feature was implemented in Paraguay, but is not being used right now.
