<li>DSpace’s own Solr logs don’t give IP addresses, so I will have to enable Nginx’s logging of <code>/solr</code> so I can see where this request came from</li>
<li>I enabled logging of <code>/rest/</code> and I think I’ll leave it on for good</li>
<li>Also, the disk is nearly full because of log file issues, so I’m running some compression on DSpace logs</li>
<li>Normally these stay uncompressed for a month just in case we need to look at them, so now I’ve just compressed anything older than 2 weeks so we can get some disk space back</li>
<li>The first one seems ok, but I don’t know what to make of the second one…</li>
<li>I had a look and there is indeed no file with the second checksum in the assetstore (ie, looking in <code>[dspace-dir]/assetstore/99/59/30/...</code>)</li>
<li>For what it’s worth, there is no item on DSpace Test or S3 backups with that checksum either…</li>
<li>I did some basic benchmarking on a local DSpace before and after the JVM settings above, but there wasn’t anything amazingly obvious</li>
<li>I want to make the changes on DSpace Test and monitor the JVM heap graphs for a few days to see if they change the JVM GC patterns or anything (munin graphs)</li>
<li>Spin up new CGSpace server on Linode</li>
<li>I did a few traceroutes from Jordan and Kenya and it seems that Linode’s Frankfurt datacenter is a few less hops and perhaps less packet loss than the London one, so I put the new server in Frankfurt</li>

<li>For what it’s worth, after running the same SQL updates on my local test server, <code>index-authority</code> runs and completes just fine</li>
<li>I will have to test more</li>
<li>Anyways, I noticed that some of the authority values I set actually have versions of author names we don’t want, ie “Grace, D.”</li>
<li>For example, do a Solr query for “first_name:Grace” and look at the results</li>

<ul>
<li>When I try using the XML format I get an error that the <code>updateLog</code> needs to be configured for that core</li>

<li>Then I’ll reindex discovery and authority and see how the authority Solr core looks</li>
<li>After this, now there are authorities for some of the “Grace, D.” and “Grace, Delia” text_values in the database (the first version is actually the same authority that already exists in the core, so it was just added back to some text_values, but the second one is new):</li>
<li>So now I could set them all to this ID and the name would be ok, but there has to be a better way!</li>
<li>In this case it seems that since there were also two different IDs in the original database, I just picked the wrong one!</li>

<li>This proves that unifying author name varieties in authorities is easy, but fixing the name in the authority is tricky!</li>

<li>Looking at logs, it seems we need to evaluate which logs we keep and for how long</li>
<li>Basically the only ones we <em>need</em> are <code>dspace.log</code> because those are used for legacy statistics (need to keep for 1 month)</li>
<li>Other logs will be an issue because they don’t have date stamps</li>
<li>I will add date stamps to the logs we’re storing from the tomcat7 user’s cron jobs at least, using: <code>$(date --iso-8601)</code></li>
<li>Would probably be better to make custom logrotate files for them in the future</li>
<li>Clean up some unneeded log files from 2014 (they weren’t large, just don’t need them)</li>
<li>So basically, new cron jobs for logs should look something like this:</li>
<li>Find any file named <code>*.log*</code> that isn’t <code>dspace.log*</code>, isn’t already zipped, and is older than one day, and zip it:</li>
<li>Since there is <code>xzgrep</code> and <code>xzless</code> we can actually just zip them after one day, why not?!</li>
<li>We can keep the zipped ones for two weeks just in case we need to look for errors, etc, and delete them after that</li>
<li>I use <code>schedtool -B</code> and <code>ionice -c2 -n7</code> to set the CPU scheduling to <code>SCHED_BATCH</code> and the IO to best effort which should, in theory, impact important system processes like Tomcat and PostgreSQL less</li>
<li>When the tasks are running you can see that the policies do apply:</li>
