Meeting with AgroKnow to discuss CGSpace, ILRI data, AReS, GARDIAN, etc
They asked if we had plans to enable RDF support in CGSpace
There have been 4,400 more downloads of the CTA Spore publication from those strange Amazon IP addresses today
I suspected that some might not be successful, because the stats show less, but today they were all HTTP 200!

<li>Maria from Bioversity emailed me a list of new ORCID identifiers for their researchers so I will add them to our controlled vocabulary
<ul>
<li>First I need to extract the ones that are unique from their list compared to our existing one:</li>
</ul></li>
</ul>

</code></pre>
<ul>
<li>We currently have 1177 unique ORCID identifiers, and this brings our total to 1237!</li>
<li>Next I will resolve all their names using my <code>resolve-orcids.py</code> script:</li>
</ul>
<pre><code>$ ./resolve-orcids.py -i /tmp/2019-04-03-orcid-ids.txt -o 2019-04-03-orcid-ids.txt -d

2019-04-03 16:40:05 +02:00
<ul>
<li>After that I added the XML formatting, formatted the file with tidy, and sorted the names in vim</li>
<li>One user&rsquo;s name has changed so I will update those using my <code>fix-metadata-values.py</code> script:</li>
</ul>
<pre><code>$ ./fix-metadata-values.py -i 2019-04-03-update-orcids.csv -db dspace -u dspace -p 'fuuu' -f cg.creator.id -m 240 -t correct -d

<li>I created a pull request and merged the changes to the 5_x-prod branch (<a href="https://github.com/ilri/DSpace/pull/417">#417</a>)</li>
<li>A few days ago I noticed some weird update process for the statistics-2018 Solr core and I see it&rsquo;s still going:</li>

<li>Interestingly, there are 5666 occurences, and they are mostly for the 2018 core:</li>

<ul>
<li>Looking at <code>iostat 1 10</code> I also see some CPU steal has come back, and I can confirm it by looking at the Munin graphs:</li>
</ul>
<p><img src="/cgspace-notes/2019/04/cpu-week.png" alt="CPU usage week" /></p>
<ul>
<li>The other thing visible there is that the past few days the load has spiked to 500% and I don&rsquo;t think it&rsquo;s a coincidence that the Solr updating thing is happening&hellip;</li>
2019-04-05 22:07:30 +02:00
<li>I ran all system updates and rebooted the server
<ul>
<li>The load was lower on the server after reboot, but Solr didn&rsquo;t come back up properly according to the Solr Admin UI:</li>
</ul></li>
</ul>

<ul>
<li>I looked and saw that the WLE website is using the Altmetric score associated with the DOI, and that the Handle has no score at all</li>
<li>I tweeted the item and I assume this will link the Handle with the DOI in the system</li>
2019-04-06 11:06:14 +02:00

<li>So definitely the <em>size</em> of the transfer is more efficient with a HEAD, but I need to wait to see if these requests show up in Solr
<ul>
<li>After twenty minutes of waiting I still don&rsquo;t see any new requests in the statistics core, but when I try the requests from the command line again I see the following in the DSpace log:</li>
</ul></li>
</ul>
<pre><code>2019-04-07 02:05:30,966 INFO org.dspace.usage.LoggerUsageEventListener @ anonymous:session_id=EF2DB6E4F69926C5555B3492BB0071A8:ip_addr=78.x.x.x:view_bitstream:bitstream_id=165818

</code></pre>
<ul>
<li>So my inclination is that both HEAD and GET requests are registered as views as far as Solr and DSpace are concerned
<ul>
<li>Strangely, the statistics Solr core says it hasn&rsquo;t been modified in 24 hours, so I tried to start the &ldquo;optimize&rdquo; process from the Admin UI and I see this in the Solr log:</li>
</ul></li>
</ul>
<pre><code>2019-04-07 02:08:44,186 INFO org.apache.solr.update.UpdateHandler @ start commit{,optimize=true,openSearcher=true,waitSearcher=true,expungeDeletes=false,softCommit=false,prepareCommit=false}
</code></pre>
<ul>
<li>Ugh, even after optimizing there are no Solr results for requests from my IP, and actually I only see 18 results from 2019-04 so far and none of them are <code>statistics_type:view</code>&hellip; very weird
<ul>
<li>I don&rsquo;t even see many hits for days after 2019-03-17, when I migrated the server to Ubuntu 18.04 and copied the statistics core from CGSpace (linode18)</li>
<li>I will try to re-deploy the <code>5_x-dev</code> branch and test again</li>
</ul></li>
<li>According to the <a href="https://wiki.duraspace.org/display/DSDOC5x/SOLR+Statistics">DSpace 5.x Solr documentation</a> the default commit time is after 15 minutes or 10,000 documents (see <code>solrconfig.xml</code>)</li>
<li>I looped some GET and HEAD requests to a bitstream on my local instance and after some time I see that they <em>do</em> register as downloads (even though they are internal):</li>
</ul>

<li>I confirmed the same on CGSpace itself after making one HEAD request</li>
<li>So I&rsquo;m pretty sure it&rsquo;s something about DSpace Test using the CGSpace statistics core, and not that I deployed Solr 4.10.4 there last week
<ul>
<li>I deployed Solr 4.10.4 locally and ran a bunch of requests for bitstreams and they do show up in the Solr statistics log, so the issue must be with re-using the existing Solr core from CGSpace</li>
</ul></li>
<li>Now this gets more frustrating: I did the same GET and HEAD tests on a local Ubuntu 16.04 VM with Solr 4.10.2 and 4.10.4 and the statistics are recorded
<ul>
<li>This leads me to believe there is something specifically wrong with DSpace Test (linode19)</li>
<li>The only thing I can think of is that the JVM is using G1GC instead of ConcMarkSweepGC</li>
</ul></li>
<li>Holy shit, all this is actually because of the GeoIP1 deprecation and a missing <code>GeoLiteCity.dat</code>
<ul>
<li>For some reason the missing GeoIP data causes stats to not be recorded whatsoever and there is no error!</li>
<li>See: <a href="https://jira.duraspace.org/browse/DS-3986">DS-3986</a></li>
<li>See: <a href="https://jira.duraspace.org/browse/DS-4020">DS-4020</a></li>
<li>See: <a href="https://jira.duraspace.org/browse/DS-3832">DS-3832</a></li>
<li>DSpace 5.10 upgraded to use GeoIP2, but we are on 5.8 so I just copied the missing database file from another server because it has been <em>removed</em> from MaxMind&rsquo;s server as of 2018-04-01</li>
<li>Now I made 100 requests and I see them in the Solr statistics&hellip; fuck my life for wasting five hours debugging this</li>

<li>Lots of problems with affiliations, I had to correct about sixty of them</li>

<ul>
<li>The matched values can be accessed with <code>cell.recon.match.name</code>, but some of the new values don&rsquo;t appear, perhaps because I edited the original cell values?</li>
<li>I ended up using this GREL expression to copy all values to a new column:</li>

<li>Otherwise, they provide the funder data in <a href="https://www.crossref.org/services/funder-registry/">CSV and RDF format</a></li>
<li>I did a quick test with the recent IITA records against reconcile-csv in OpenRefine and it matched a few, but the ones that didn&rsquo;t match will need a human to go and do some manual checking and informed decision making&hellip;</li>

<ul>
<li>They can&rsquo;t seem to understand the Altmetric + Twitter flow for associating Handles and DOIs</li>
<li>To make things worse, many of their items DON&rsquo;T have DOIs, so when Altmetric harvests them of course there is no link! - Then, a bunch of their items don&rsquo;t have scores because they never tweeted them!</li>
<li>They added a DOI to this old item <a href="https://cgspace.cgiar.org/handle/10568/97087"><sup>10567</sup>&frasl;<sub>97087</sub></a> this morning and wonder why Altmetric&rsquo;s score hasn&rsquo;t linked with the DOI magically</li>
<li>We should check in a week to see if Altmetric will make the association after one week when they harvest again</li>

<li>I copied the <code>statistics</code> and <code>statistics-2018</code> Solr cores from CGSpace to my local machine and watched the Java process in VisualVM while indexing item views and downloads with my <a href="https://github.com/ilri/dspace-statistics-api">dspace-statistics-api</a>:</li>
</ul>
<p><img src="/cgspace-notes/2019/04/visualvm-solr-indexing.png" alt="Java GC during Solr indexing with CMS" /></p>
<ul>
<li>It took about eight minutes to index 784 pages of item views and 268 of downloads, and you can see a clear &ldquo;sawtooth&rdquo; pattern in the garbage collection</li>
<li>I am curious if the GC pattern would be different if I switched from the <code>-XX:+UseConcMarkSweepGC</code> to G1GC</li>
<li>I switched to G1GC and restarted Tomcat but for some reason I couldn&rsquo;t see the Tomcat PID in VisualVM&hellip;
<ul>
<li>Anyways, the indexing process took much longer, perhaps twice as long!</li>
</ul></li>
<li>I tried again with the GC tuning settings from the Solr 4.10.4 release:</li>

<li>Pretty annoying to see CGSpace (linode18) with 2050% CPU steal according to <code>iostat 1 10</code>, though I haven&rsquo;t had any Linode alerts in a few days</li>
<li>Abenet sent me a list of ILRI items that don&rsquo;t have CRPs added to them
<ul>
<li>The spreadsheet only had Handles (no IDs), so I&rsquo;m experimenting with using Python in OpenRefine to get the IDs</li>
<li>I cloned the handle column and then did a transform to get the IDs from the CGSpace REST API:</li>
</ul></li>
</ul>
<pre><code>import json
import re
import urllib
import urllib2
handle = re.findall('[0-9]+/[0-9]+', value)
url = 'https://cgspace.cgiar.org/rest/handle/' + handle[0]
req = urllib2.Request(url)
req.add_header('User-agent', 'Alan Python bot')
res = urllib2.urlopen(req)
data = json.load(res)
item_id = data['id']
return item_id
</code></pre>
<ul>
<li>Luckily none of the items already had CRPs, so I didn&rsquo;t have to worry about them getting removed
<ul>
<li>It would have been much trickier if I had to get the CRPs for the items first, then add the CRPs&hellip;</li>
