Hello All, (We are running on DSpace 1.8.2)
I was looking at our stats data for the last year and a half and I noticed periodical drops in views/downloads which are inconsistent with the overall usage pattern. (I did not filter out bots for that exercise.) Numbers dropped for 1 to 5 days to below 10 and even to 0 sometimes (from an average of about 5000 per day). I counted about 8 such events since Jan 2013. (There are possibly more which don't stand out as much.) Our DSpace was always running and being monitored during that period. In our set-up we record stats in both Solr and ElasticSearch (at least we have done for the last half year). The data for ElasticSearch do not show drops for the days where Solr has data gaps. ElsaticSearch stats recording is triggered by the same DSpace events as Solr is. Unfortunately we have not kept log files for the periods with Solr data gaps. Has anyone else seen unexpected fluctuations in their stats? Anyone any idea of what could cause it. DSpace and Solr were running at the time since there are some data just not enough. To look at the data I use for views http://localhost:8080/solr/statistics/select/?q=type+%3A+2+&version=2.2&start=0&rows=0&indent=on&facet=true&facet.range=time&f.time.facet.range.start=2013-01-01T00:00:00Z&f.time.facet.range.gap=%2B1DAY&f.time.facet.range.end=2014-04-11T00:00:00Z downloads http://localhost:8080/solr/statistics/select/?q=type+%3A+0+&version=2.2&start=0&rows=0&indent=on&facet=true&facet.range=time&f.time.facet.range.start=2013-01-01T00:00:00Z&f.time.facet.range.gap=%2B1DAY&f.time.facet.range.end=2014-04-11T00:00:00Z Interestingly we can prove that there were more events. Any comments welcome :-) Best regards, Anja ------------------------------------------------------------------------------ Put Bad Developers to Shame Dominate Development with Jenkins Continuous Integration Continuously Automate Build, Test & Deployment Start a new project now.
