<ul>
<li>Continue with processing the statistics-2019 Solr core with the AtomicStatisticsUpdateCLI tool on DSpace Test
<ul>
<li>So far we’ve spent at least fifty hours to process the statistics and statistics-2019 core… wow.</li>
</ul>
</li>
</ul>
<h2 id="2020-11-02">2020-11-02</h2>
<ul>
<li>Talk to Moayad and fix a few issues on OpenRXV:
<ul>
<li>Incorrect views and downloads (caused by Elasticsearch’s default result set size of 10)</li>
<li>Invalid share link</li>
<li>Missing “https://” for Handles in the Simple Excel report (caused by using the <code>handle</code> instead of the <code>uri</code>)</li>
<li>Sorting the list of items by views</li>
</ul>
</li>
<li>I resumed the processing of the statistics-2018 Solr core after it spent 20 hours to get to 60%</li>
</ul>
<h2 id="2020-11-04">2020-11-04</h2>
<ul>
<li>After 29 hours the statistics-2017 core finished processing so I started the statistics-2016 core on DSpace Test</li>
</ul>
<h2 id="2020-11-05">2020-11-05</h2>
<ul>
<li>Peter sent me corrections and deletions for the author affiliations
<ul>
<li>I quickly proofed them for UTF-8 issues in OpenRefine and csv-metadata-quality and then tested them locally and then applied them on CGSpace:</li>
</ul>
</li>
</ul>
<pre><code>$ ./fix-metadata-values.py -i 2020-11-05-fix-862-affiliations.csv -db dspace -u dspace -p 'fuuu' -f cg.contributor.affiliation -t 'correct' -m 211
$ ./delete-metadata-values.py -i 2020-11-05-delete-29-affiliations.csv -db dspace -u dspace -p 'fuuu' -f cg.contributor.affiliation -m 211
</code></pre><ul>
<li>Then I started a Discovery re-index on CGSpace:</li>
</ul>
<pre><code>$ time chrt -b 0 ionice -c2 -n7 nice -n19 dspace index-discovery -b
real 92m24.993s
user 8m11.858s
sys 2m26.931s
</code></pre><h2 id="2020-11-06">2020-11-06</h2>
<ul>
<li>Restart the AtomicStatisticsUpdateCLI processing of the statistics-2016 core on DSpace Test after 20 hours…
<ul>
<li>This phase finished after five hours so I started it on the statistics-2015 core</li>
</ul>
</li>
</ul>
<h2 id="2020-11-07">2020-11-07</h2>
<ul>
<li>Atmire responded about the issue with duplicate values in owningComm and containerCommunity etc
<ul>
<li>I told them to please look into it and use some of our credits if need be</li>
</ul>
</li>
<li>The statistics-2015 core finished after 20 hours so I started the statistics-2014 core</li>
</ul>
<h2 id="2020-11-08">2020-11-08</h2>
<ul>
<li>Add “Data Paper” to types on CGSpace</li>
<li>Add “SCALING CLIMATE-SMART AGRICULTURE” to CCAFS subjects on CGSpace</li>
<li>Add “ANDEAN ROOTS AND TUBERS” to CIP subjects on CGSpace</li>
<li>Add CGIAR System subjects to Discovery sidebar facets on CGSpace
<ul>
<li>Also add the System subject to item view on CGSpace</li>
</ul>
</li>
<li>The statistics-2014 core finished processing after five hours, so I started processing the statistics-2013 core on DSpace Test</li>
<li>Since I was going to restart CGSpace and update the Discovery indexes anyways I decided to check for any straggling upper case AGROVOC entries and lower case them:</li>
</ul>
<pre><code>dspace=# BEGIN;
dspace=# UPDATE metadatavalue SET text_value=LOWER(text_value) WHERE resource_type_id=2 AND metadata_field_id=57 AND text_value ~ '[[:upper:]]';
UPDATE 164
dspace=# COMMIT;
</code></pre><ul>
<li>Run system updates on CGSpace (linode18) and reboot it
<ul>
<li>I had to restart Tomcat once after the machine started up to get all Solr statistics cores to load properly</li>
</ul>
</li>
<li>After about ten more hours the rest of the Solr statistics cores finished processing on DSpace Test and I started optimizing them in Solr admin UI</li>
</ul>
<h2 id="2020-11-10">2020-11-10</h2>
<ul>
<li>I am noticing that CGSpace doesn’t have any statistics showing for years before 2020, but all cores are loaded successfully in Solr Admin UI… strange
<ul>
<li>I restarted Tomcat and I see in Solr Admin UI that the statistics-2015 core failed to load</li>
<li>Looking in the DSpace log I see:</li>
</ul>
</li>
</ul>

<li>Seems that the core gets probed twice… perhaps a threading issue?
<ul>
<li>The only thing I can think of is the <code>acceptorThreadCount</code> parameter in Tomcat’s server.xml, which has been set to 2 since 2018-01 (we started sharding the Solr statistics cores in 2019-01 and that’s when this problem arose)</li>
<li>I will try reducing that to 1</li>
<li>Wow, now it’s even worse:</li>
</ul>

</code></pre><ul>
<li>Could it be because we have two Tomcat connectors?
<ul>
<li>I restarted Tomcat a few more times before all cores loaded, and still there are no stats before 2020-01… hmmmmm</li>
</ul>
</li>
<li>I added a <a href="https://github.com/ilri/OpenRXV/commit/3816b9b3f3d9182d2ba1a899c1017c5895a59dee">lowercase formatter to OpenRXV</a> so that we can lowercase AGROVOC subjects during harvesting</li>
</ul>
<h2 id="2020-11-11">2020-11-11</h2>
<ul>
<li>Atmire responded with a quote for the work to fix the duplicate owningComm, etc in our Solr data
<ul>
<li>I told them to proceed, as it’s within our budget of credits</li>
<li>They will write a processor for DSpace 6 to remove the duplicates</li>
</ul>
</li>
<li>I did some tests to add a usage statistics chart to the item views on DSpace Test
<ul>
<li>It is inspired by Salem’s work on WorldFish’s repository, and it hits the dspace-statistics-api for the current item and displays a graph</li>
<li>I got it working very easily for all-time statistics with Chart.js, but I think I will need to use Highcharts or something else because Chart.js is HTML5 canvas and doesn’t allow theming via CSS (so our Bootstrap brand colors for each theme won’t work)</li>
<li>I think I’ll pursue this after the DSpace 6 upgrade…</li>
</ul>
</li>
</ul>
<h2 id="2020-11-12">2020-11-12</h2>
<ul>
<li>I was looking at Solr again trying to find a way to get community and collection stats by faceting on <code>owningComm</code> and <code>owningColl</code> and it seems to work actually
<ul>
<li>The duplicated values in the multi-value fields don’t seem to affect the counts, as I had thought previously (though we should still get rid of them)</li>
<li>One major difference between the raw numbers I was looking at and Atmire’s numbers is that Atmire’s code filters “Internal” IP addresses…</li>
<li>Also, instead of doing <code>isBot:false</code> I think I should do <code>-isBot:true</code> because it’s not a given that all documents will have this field and have it false, but we can definitely exclude the ones that have it as true</li>
</ul>
</li>
<li>First we get the total number of communities with stats (using calcdistinct):</li>
</ul>
<pre><code>facet=true&facet.field=owningComm&facet.mincount=1&facet.limit=1&facet.offset=0&stats=true&stats.field=owningComm&stats.calcdistinct=true&shards=http://localhost:8081/solr/statistics,http://localhost:8081/solr/statistics-2019,http://localhost:8081/solr/statistics-2018,http://localhost:8081/solr/statistics-2017,http://localhost:8081/solr/statistics-2016,http://localhost:8081/solr/statistics-2015,http://localhost:8081/solr/statistics-2014,http://localhost:8081/solr/statistics-2013,http://localhost:8081/solr/statistics-2012,http://localhost:8081/solr/statistics-2011,http://localhost:8081/solr/statistics-2010
</code></pre><ul>
<li>Then get stats themselves, iterating 100 items at a time with limit and offset:</li>
</ul>
<pre><code>facet=true&facet.field=owningComm&facet.mincount=1&facet.limit=100&facet.offset=0&shards=http://localhost:8081/solr/statistics,http://localhost:8081/solr/statistics-2019,http://localhost:8081/solr/statistics-2018,http://localhost:8081/solr/statistics-2017,http://localhost:8081/solr/statistics-2016,http://localhost:8081/solr/statistics-2015,http://localhost:8081/solr/statistics-2014,http://localhost:8081/solr/statistics-2013,http://localhost:8081/solr/statistics-2012,http://localhost:8081/solr/statistics-2011,http://localhost:8081/solr/statistics-2010
</code></pre><ul>
<li>I was surprised to see 10,000,000 docs with <code>isBot:true</code> when I was testing on DSpace Test…
<ul>
<li>This has got to be a mistake of some kind, as I see 4 million in 2014 that are from <code>dns:localhost.</code>, perhaps that’s when we didn’t have useProxies set up correctly?</li>
<li>I don’t see the same thing on CGSpace… I wonder what happened?</li>
<li>Perhaps they got re-tagged during the DSpace 6 upgrade, somehow during the Solr migration? Hmmmmm. Definitely have to be careful with <code>isBot:true</code> in the future and not automatically purge these!!!</li>
</ul>
</li>
<li>I noticed 120,000+ hits from monit, FeedBurner, and Blackboard Safeassign in 2014, 2015, 2016, 2017, etc…
<ul>
<li>I hadn’t seen monit before, but the others are already in DSpace’s spider agents lists for some time so probably only appear in older stats cores</li>
<li>The issue with purging these using <code>check-spider-hits.sh</code> is that it can’t do case-insensitive regexes and some metacharacters like <code>\s</code> don’t work so I added case-sensitive patterns to a local agents file and purged them with the script</li>
</ul>
