Sugar Network/Node Statistics

Summary

This page describes the statistics that Sugar Network nodes generate. The statistics are about the entire server and not personalized. Note that the statistics are targeted for the interests of educational researchers rather than service maintainers, for technical details look for HTTP stats.

Statistics will be collected by analyzing regular requests to an API server and stored for each Sugar Network node. It will be possible to get direct access to these stats using node's API.

Common statistics

Statistics will be collected per Sugar Network resource type.

• users
  Total number of existing User objects;
• contexts
  Total number of existing Context objects;
• released
  Average number of newly uploaded Context.releases for specified time frame;
• solved
  Average number of requested Context solutions for specified time frame; note that this stats value does not equal to the number of solution usages on client side since solutions might be cached;
• reported
  Average number of newly uploaded failure Reports objects for specified time frame;
• topics
  Total number of top-level Post objects;
• posts
  Total number of dependent Post objects.

Per object statistics

While calculating common statistics, nodes generate per object sums as well.

These are the Sugar Network resources that will be affected:

Context properties:

• Context.rating
  Average rating given to the Context while reviewing, rating value is a tuple of votes sum and number of reviews;
• Context.retrieves
  Number of retrieves of Context releases.

Post properties:

• Post.rating
  Average rating given to the Post while reviewing, rating value is a tuple of votes sum and number of reviews.
