<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>

<ul>
|

<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>

<li>So my inclination is that both HEAD and GET requests are registered as views as far as Solr and DSpace are concerned
|

<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>

<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>

<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>
