<li>Update <ahref="https://github.com/ilri/dspace-statistics-api">dspace-statistics-api</a> for DSpace 6+ UUIDs
<ul>
<li>Tag version 1.2.0 on GitHub</li>
</ul>
</li>
<li>Test migrating legacy Solr statistics to UUIDs with the as-of-yet unreleased <ahref="https://github.com/DSpace/DSpace/commit/184f2b2153479045fba6239342c63e7f8564b8b6#diff-0350ce2e13b28d5d61252b7a8f50a059">SolrUpgradePre6xStatistics.java</a>
<ul>
<li>You need to download this into the DSpace 6.x source and compile it</li>
<li>Skype with Peter and Abenet to discuss the CG Core survey
<ul>
<li>We also discussed some other CGSpace issues</li>
</ul>
</li>

<li>Abenet asked me to add some new ILRI subjects to CGSpace
<ul>
<li>I <ahref="https://github.com/ilri/DSpace/commit/b51a242e773bd8658d3cab4ac883975708b00386">updated the input-forms.xml</a> in our <code>5_x-prod</code> branch on GitHub</li>
<li>Abenet said we are changing <code>HEALTH</code> to <code>HUMAN HEALTH</code> so I need to fix those using my <code>fix-metadata-values.py</code> script:</li>
<li>I found a very <ahref="https://lucene.apache.org/solr/guide/8_1/solr-system-requirements.html#lucene-solr-prior-to-7-0">interesting comment on the Solr 8.1 guide</a> about Java compatibility:</li>
</ul>
<blockquote>
<p>Lucene/Solr 7.0 was the first version that successfully passed our tests using Java 9 and higher. You should avoid Java 9 or later for Lucene/Solr 6.x or earlier.</p>

<li>I want to try to consolidate our yearly Solr statistics cores back into one <code>statistics</code> core using the solr-import-export-json tool</li>
<li>I will try it on DSpace test, doing one year at a time:</li>
</ul>
<pre><code>$ ./run.sh -s http://localhost:8081/solr/statistics-2010 -a export -o /tmp/statistics-2010.json -k uid
$ ./run.sh -s http://localhost:8081/solr/statistics -a import -o /tmp/statistics-2010.json -k uid
<li>Upgrade PostgreSQL from 9.6 to 10 on DSpace Test (linode19)
<ul>
<li>I’ve been running it for one month in my local environment, and others have reported on the dspace-tech mailing list that they are using 10 and 11</li>
<li>Peter noticed that the Solr stats were not showing anything before 2020
<ul>
<li>I had to restart Tomcat three times before all cores loaded properly…</li>
</ul>
</li>
</ul>
<h2id="2020-03-10">2020-03-10</h2>
<ul>
<li>Fix some logic issues in the nginx config
<ul>
<li>Use generic blocking of <code>[Bb]ot</code> and <code>[Cc]rawl</code> and <code>[Ss]pider</code> in the “badbots” rate limiting logic instead of trying to list them all one by one (bots should not be trying to index dynamic pages <em>no matter what</em> so we punish hard here)</li>
<li>We were not properly forwarding the remote IP address to Tomcat in all nginx location blocks, which led some locations to log a hit from 127.0.0.1 (because we need to explicitly add the global proxy params when setting other headers in location blocks)</li>
<li>Unfortunately this affected the REST API and there are a few hundred thousand requests from this user agent:</li>

<li>Shit, and something happened and a few thousand hits from user agents with “Bot” in their user agent got through

<li>I need to re-run the <code>check-bot-hits.sh</code> script with the standard COUNTER-Robots list again, but add my own versions of a few because the script/Solr doesn’t support case-insensitive regular expressions:</li>

<li>I’m working on the 170 IITA records on <ahref="https://dspacetest.cgiar.org/handle/10568/106567">DSpace Test</a> from January finally
<ul>
<li>It’s been two months since I last looked and I want to do a thorough check to make sure Bosede didn’t introduce any new issues, but I want to consolidate all the text languages for these records so it’s easier to check them in OpenRefine</li>
<li>First I got a list of IDs from <code>csvcut</code> and then I updated the text languages for only those records:</li>

<li>Then I exported the metadata from DSpace Test and imported it into OpenRefine
<ul>
<li>I corrected one invalid AGROVOC subject using my <code>csv-metadata-quality</code> script</li>
</ul>
</li>
<li>I exported a new list of affiliations from the database, added line numbers with <code>csvcut</code>, and then validated them in OpenRefine using <code>reconcile-csv</code>:</li>
</ul>
<pre><code>dspace=# \COPY (SELECT DISTINCT text_value, count(*) FROM metadatavalue WHERE resource_type_id = 2 AND metadata_field_id = 211 GROUP BY text_value ORDER BY count DESC LIMIT 1500) to /tmp/2020-03-12-affiliations.csv WITH CSV HEADER;`
<li>I always forget how to copy the reconciled values in OpenRefine, but you need to make a new column and populate it using this GREL: <code>if(cell.recon.matched, cell.recon.match.name, value)</code></li>
<li>I mapped all 170 items to their appropriate collections based on type and uploaded them to CGSpace</li>
<li>I’m looking at the CPU usage of CGSpace (linode18) over the past year and I see we <em>rarely</em> even go over two CPUs on average sustained usage:</li>
</ul>
<p><imgsrc="/cgspace-notes/2020/03/cgspace-cpu-year.png"alt="linode18 CPU usage year"></p>
<ul>
<li>Also clearly visible is the effect of CPU steal in 2019-03</li>
<li>At max we have committed 10GB of RAM, the rest is used opportunistically by the filesystem cache, likely for Solr
<ul>
<li>There was a huge drop in 2019-07 when I changed the JVM settings</li>
<li>I think we should re-evaluate our deployment and perhaps target a different instance type and add block storage for assetstore (as we determined Linode’s block storage to be too slow for Solr)</li>
<li>I sent Atmire a message to ask if they managed to start working on the DSpace 6 port, as the last communication was twenty-six days ago when they said they were going to secure technical resources to do so</li>
<li>Start adapting the <code>dspace</code> role in our <ahref="https://github.com/ilri/rmg-ansible-public">Ansible infrastructure playbooks</a> for DSpace 6 support</li>
<li>More work adapting the <code>dspace</code> role in our Ansible infrastructure scripts to DSpace 6</li>
<li>Update Tomcat to version 7.0.103 in the Ansible infrastrcutrue playbooks and deploy on DSpace Test (linode26)</li>
<li>Maria sent me a few new ORCID identifiers from Bioversity so I combined them with our existing ones, filtered the unique ones, and then resolved their names using my <code>resolve-orcids.py</code> script:</li>
<li><ahref="https://hdl.handle.net/10568/106899">The second item</a> had no donut so I <ahref="https://twitter.com/mralanorth/status/1243158045540134913">tweeted its handle</a></li>

</ul>

<li>Abenet pointed out <ahref="https://hdl.handle.net/10568/106573">one item</a> that she had tweeted last week that is missing a donut as well, so I <ahref="https://twitter.com/mralanorth/status/1243163710241345536">tweeted it</a> too</li>
<li>Add two more Bioversity ORCID iDs to CGSpace and then tag ~70 of the authors’ existing publications in the database using this CSV with my <code>add-orcid-identifiers-csv.py</code> script:</li>
<li>Deploy latest Bioversity and CIAT updates on CGSpace (linode18) and DSpace Test (linode26)</li>
<li>Deploy latest Ansible infrastructure playbooks on CGSpace and DSpace Test to get the latest dspace-statistics-api (v1.1.1) and Tomcat (7.0.103) versions</li>
<li>Run system updates on CGSpace and DSpace Test and reboot them
<ul>
<li>After reboot all the Solr statistics cores came back up on the first time on both servers (yay)</li>
