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 for use only by a particular deployment).

Counter types

Measured statistic values might be one of the following types:

  • absolute
    value to use as-is, e.g., amount of free disk space;
  • uptime
    number of seconds since event start, e.g., how long window is active; if event is not active, value will be reset to zero;
  • gauge
    is for things like temperatures or number of people in a room, i.e., value can grow and fall in time;
  • counter
    a counter, number of times event was triggered during single time frame; value can be more or equal to zero.

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.
