<li>I was trying to add Felix Shaw’s account back to the Administrators group on DSpace Test, but I couldn’t find his name in the user search of the groups page
<ul>
<li>If I searched for “Felix” or “Shaw” I saw other matches, included one for his personal email address!</li>
<li>I ended up finding him via searching for his email address</li>
<li>The other thing visible there is that the past few days the load has spiked to 500% and I don’t think it’s a coincidence that the Solr updating thing is happening…</li>
<li>Udana asked why item <ahref="https://cgspace.cgiar.org/handle/10568/91278"><sup>10568</sup>⁄<sub>91278</sub></a> didn’t have an Altmetric badge on CGSpace, but on the <ahref="https://wle.cgiar.org/food-and-agricultural-innovation-pathways-prosperity">WLE website</a> it does
<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>
<li>Linode sent an alert that there was high CPU usage this morning on CGSpace (linode18) and these were the top IPs in the webserver access logs around the time:</li>
<li><code>45.5.184.72</code> is in Colombia so it’s probably CIAT, and I see they are indeed trying to get crawl the Discover pages on CIAT’s datasets collection:</li>
<li>Their user agent is the one I added to the badbots list in nginx last week: “GuzzleHttp/6.3.3 curl/7.47.0 PHP/7.0.30-0ubuntu0.16.04.1”</li>
<li>They made 22,000 requests to Discover on this collection today alone (and it’s only 11AM):</li>
<li>I need to find a contact at CIAT to tell them to use the REST API rather than crawling Discover</li>
<li>Maria from Bioversity recommended that we use the phrase “AGROVOC subject” instead of “Subject” in Listings and Reports
<ul>
<li>I made a pull request to update this and merged it to the <code>5_x-prod</code> branch (<ahref="https://github.com/ilri/DSpace/pull/418">#418</a>)</li>
<li>Looking into the impact of harvesters like <code>45.5.184.72</code>, I see in Solr that this user is not categorized as a bot so it definitely impacts the usage stats by some tens of thousands <em>per day</em></li>
<li>I am trying to see if these are registered as downloads in Solr or not</li>
<li>I see 96,925 downloads from their AWS gateway IPs in 2019-03:</li>
</ul></li>

<li>Making some tests on GET vs HEAD requests on the <ahref="https://dspacetest.cgiar.org/handle/10568/100289">CTA Spore 192 item</a> on DSpace Test:</li>
</ul>
<pre><code>$ http --print Hh GET https://dspacetest.cgiar.org/bitstream/handle/10568/100289/Spore-192-EN-web.pdf
GET /bitstream/handle/10568/100289/Spore-192-EN-web.pdf HTTP/1.1
<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’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’t been modified in 24 hours, so I tried to start the “optimize” 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>… very weird
<ul>
<li>I don’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 <ahref="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>

<ul>
<li>I confirmed the same on CGSpace itself after making one HEAD request</li>
<li>So I’m pretty sure it’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>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’s server as of 2018-04-01</li>
<li>Now I made 100 requests and I see them in the Solr statistics… fuck my life for wasting five hours debugging this</li>
<li>UptimeRobot said CGSpace went down and up a few times tonight, and my first instict was to check <code>iostat 1 10</code> and I saw that CPU steal is around 10–30 percent right now…</li>
<li>The load average is super high right now, as I’ve noticed the last few times UptimeRobot said that CGSpace went down:</li>
</ul>
<pre><code>$ cat /proc/loadavg
10.70 9.17 8.85 18/633 4198
</code></pre>
<ul>
<li>According to the server logs there is actually not much going on right now:</li>
<li>Start checking IITA’s last round of batch uploads from <ahref="https://dspacetest.cgiar.org/handle/10568/100333">March on DSpace Test</a> (20193rd.xls)
<ul>
<li>Lots of problems with affiliations, I had to correct about sixty of them</li>
<li>I used lein to host the latest CSV of our affiliations for OpenRefine to reconcile against:</li>
</ul></li>
</ul>
<pre><code>$ lein run ~/src/git/DSpace/2019-02-22-affiliations.csv name id
</code></pre>
<ul>
<li>After matching the values and creating some new matches I had trouble remembering how to copy the reconciled values to a new column
<ul>
<li>The matched values can be accessed with <code>cell.recon.match.name</code>, but some of the new values don’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>See the <ahref="https://github.com/OpenRefine/OpenRefine/wiki/Variables#recon">OpenRefine variables documentation</a> for more notes about the <code>recon</code> object</li>
<li>I also noticed a handful of errors in our current list of affiliations so I corrected them:</li>
<pre><code>dspace=# \COPY (SELECT DISTINCT text_value, count(*) FROM metadatavalue WHERE metadata_field_id = 211 AND resource_type_id = 2 GROUP BY text_value ORDER BY count DESC LIMIT 1500) to /tmp/2019-04-08-top-1500-affiliations.csv WITH CSV HEADER;
COPY 1500
</code></pre>
<ul>
<li>Fix a few more messed up affiliations that have return characters in them (use Ctrl-V Ctrl-M to re-create control character):</li>
</ul>
<pre><code>dspace=# UPDATE metadatavalue SET text_value='International Institute for Environment and Development' WHERE resource_type_id = 2 AND metadata_field_id = 211 AND text_value LIKE 'International Institute^M%';
dspace=# UPDATE metadatavalue SET text_value='Kenya Agriculture and Livestock Research Organization' WHERE resource_type_id = 2 AND metadata_field_id = 211 AND text_value LIKE 'Kenya Agricultural and Livestock Research^M%';
</code></pre>
<ul>
<li>I noticed a bunch of subjects and affiliations that use stylized apostrophes so I will export those and then batch update them:</li>
</ul>
<pre><code>dspace=# \COPY (SELECT DISTINCT text_value FROM metadatavalue WHERE resource_type_id = 2 AND metadata_field_id = 211 AND text_value LIKE '%’%') to /tmp/2019-04-08-affiliations-apostrophes.csv WITH CSV HEADER;
COPY 60
dspace=# \COPY (SELECT DISTINCT text_value FROM metadatavalue WHERE resource_type_id = 2 AND metadata_field_id = 57 AND text_value LIKE '%’%') to /tmp/2019-04-08-subject-apostrophes.csv WITH CSV HEADER;
COPY 20
</code></pre>
<ul>
<li>I cleaned them up in OpenRefine and then applied the fixes on CGSpace and DSpace Test:</li>
