Goal
All CRUD logs are aggregated at coordinating nodes.
Summary

Aggregation of CRUD operation logs is used to compute use statistics and other summary types of information. The original log information should be viewable by administrators for some period of time.

The particular information required to be logged still needs to be specified so that MNs know what specific information needs to be collected as part of Use Case 16.

Actors
  • Member Node(s)
  • Coordinating Node
Preconditions
  • CNs are operational
Triggers
  • Timed event, logs are aggregated every 24 hours.
Post Conditions
  • Aggregate logs are stored on Coordinating Node
  • Logs are synchronized between CNs
  • Log processing is triggered on CNs
