SUNScholar/SOLR Statistics

Back to Statistics

PLEASE NOTE:

New statistics fields were introduced in DSpace 4.X, therefore any upgrade from a DSpace version less than 3.X will not have these fields.

The lack of these new fields in statistics records from previous versions of DSpace, causes major errors when attempting to do statistics maintenance in DSpace versions => 3.X after an upgrade from a lower version of DSpace. See the link below for a possible fix.

Because of this problem, we have moved to using Elastic Statistics instead, which seems to be more stable.

The issue is being discussed on this wiki page: https://wiki.duraspace.org/display/DSPACE/DSpace+statistics+-+current+status+and+future+development

Also see: https://jira.duraspace.org/browse/DS-2541 and https://github.com/DSpace/DSpace/pull/905 about work to automatically fix old statistics databases.

Introduction

SOLR Statistics was introduced with DSpace version 1.6.2, but did not work well until DSpace version 1.8.2.

SOLR statistics are enabled by default for the XMLUI in DSpace versions => 3.2.
