We have found a problem that has been affecting the EventLogging data for one month. Since March 22, 2015 there have been several gaps (of around 1-2 hours length each) without data in all schema tables.

You can see the details in the following links:

Technical discussion:

The problem still persists, although with less frequency due to sampling added to the Edit schema events, that have reduced EL throughput.

Next steps:

* The backfilling of the data gaps will be carried out this week.

* Implement a patch to avoid the problem ASAP.

* Implement a consistent solution to EventLogging scaling problems.

* Backfill any gaps that occur during implementation of the solutions.
