Peter noticed that there were 5.2 million hits on CGSpace in 2019-10 according to the Atmire usage statistics
I looked in the nginx logs and see 4.6 million in the access logs, and 1.2 million in the API logs:
# zcat --force /var/log/nginx/*access.log.*.gz | grep -cE &quot;[0-9]{1,2}/Oct/2019&quot;
4671942
# zcat --force /var/log/nginx/{rest,oai,statistics}.log.*.gz | grep -cE &quot;[0-9]{1,2}/Oct/2019&quot;
1277694
So 4.6 million from XMLUI and another 1.2 million from API requests
Let&rsquo;s see how many of the REST API requests were for bitstreams (because they are counted in Solr stats):
# zcat --force /var/log/nginx/rest.log.*.gz | grep -c -E &quot;[0-9]{1,2}/Oct/2019&quot;
1183456
# zcat --force /var/log/nginx/rest.log.*.gz | grep -E &quot;[0-9]{1,2}/Oct/2019&quot; | grep -c -E &quot;/rest/bitstreams&quot;

- As far as I can tell, none of their requests are counted in the Solr statistics:

<pre><code>
- Still, those requests are CPU intensive so I will add their user agent to the &quot;badbots&quot; rate limiting in nginx to reduce the impact on server load
- After deploying it I checked by setting my user agent to Amazonbot and making a few requests (which were denied with HTTP 503):

- On the topic of spiders, I have been wanting to update DSpace's default list of spiders in `config/spiders/agents`, perhaps by dropping a new list in from [Atmire's COUNTER-Robots](https://github.com/atmire/COUNTER-Robots) project
- First I checked for a user agent that is in COUNTER-Robots, but NOT in the current `dspace/config/spiders/example` list
- Then I made some item and bitstream requests on DSpace Test using that user agent:
</code></pre>
<p>$ http &ndash;print Hh &lsquo;<a href="https://dspacetest.cgiar.org/handle/10568/105487'">https://dspacetest.cgiar.org/handle/10568/105487'</a> User-Agent:&ldquo;iskanie&rdquo;

<pre><code>
- A bit later I checked Solr and found three requests from my IP with that user agent this month:
</code></pre>

- Now I want to make similar requests with a user agent that is included in DSpace's current user agent list:

<pre><code>
- After twenty minutes I didn't see any requests in Solr, so I assume they did not get logged because they matched a bot list...
- What's strange is that the Solr spider agent configuration in `dspace/config/modules/solr-statistics.cfg` points to a file that doesn't exist...
</code></pre>
<p>spider.agentregex.regexfile = ${dspace.dir}/config/spiders/Bots-2013-03.txt</p>
<pre><code>
- Apparently that is part of Atmire's CUA, despite being in a standard DSpace configuration file...
- I tried with some other garbage user agents like &quot;fuuuualan&quot; and they were visible in Solr
- Now I want to try adding &quot;iskanie&quot; and &quot;fuuuualan&quot; to the list of spider regexes in `dspace/config/spiders/example` and then try to use DSpace's &quot;mark spiders&quot; feature to change them to &quot;isBot:true&quot; in Solr
- I restarted Tomcat and ran `dspace stats-util -m` and it did some stuff for awhile, but I still don't see any items in Solr with `isBot:true`
- According to `dspace-api/src/main/java/org/dspace/statistics/util/SpiderDetector.java` the patterns for user agents are loaded from any file in the `config/spiders/agents` directory
- I downloaded the COUNTER-Robots list to DSpace Test and overwrote the example file, then ran `dspace stats-util -m` and still there were no new items marked as being bots in Solr, so I think there is still something wrong
- Jesus, the code in `./dspace-api/src/main/java/org/dspace/statistics/util/StatisticsClient.java` says that `stats-util -m` marks spider requests by their IPs, not by their user agents... WTF:
</code></pre>
<p>else if (line.hasOption(&rsquo;m&rsquo;))
{
SolrLogger.markRobotsByIP();
}</p>
<pre><code>
- WTF again, there is actually a function called `markRobotByUserAgent()` that is never called anywhere!
- It appears to be unimplemented...
- I sent a message to the dspace-tech mailing list to ask if I should file an issue
## 2019-11-05
- I added &quot;alanfuu2&quot; to the example spiders file, restarted Tomcat, then made two requests to DSpace Test:
</code></pre>
<p>$ http &ndash;print Hh &lsquo;<a href="https://dspacetest.cgiar.org/handle/10568/105487'">https://dspacetest.cgiar.org/handle/10568/105487'</a> User-Agent:&ldquo;alanfuuu1&rdquo;
$ http &ndash;print Hh &lsquo;<a href="https://dspacetest.cgiar.org/handle/10568/105487'">https://dspacetest.cgiar.org/handle/10568/105487'</a> User-Agent:&ldquo;alanfuuu2&rdquo;</p>
<pre><code>
- After committing the changes in Solr I saw one request for &quot;alanfuu1&quot; and no requests for &quot;alanfuu2&quot;:
</code></pre>
<p>$ http &ndash;print b &lsquo;<a href="http://localhost:8081/solr/statistics/update?commit=true'">http://localhost:8081/solr/statistics/update?commit=true'</a>

<pre><code>
- So basically it seems like a win to update the example file with the latest one from Atmire's COUNTER-Robots list
- Even though the &quot;mark by user agent&quot; function is not working (see email to dspace-tech mailing list) DSpace will still not log Solr events from these user agents
- I'm curious how the special character matching is in Solr, so I will test two requests: one with &quot;www.gnip.com&quot; which is in the spider list, and one with &quot;www.gnyp.com&quot; which isn't:

<p>$ http &ndash;print Hh &lsquo;<a href="https://dspacetest.cgiar.org/handle/10568/105487'">https://dspacetest.cgiar.org/handle/10568/105487'</a> User-Agent:&ldquo;www.gnip.com&rdquo;
$ http &ndash;print Hh &lsquo;<a href="https://dspacetest.cgiar.org/handle/10568/105487'">https://dspacetest.cgiar.org/handle/10568/105487'</a> User-Agent:&ldquo;www.gnyp.com&rdquo;</p>
<pre><code>
- Then commit changes to Solr so we don't have to wait:
</code></pre>
<p>$ http &ndash;print b &lsquo;<a href="http://localhost:8081/solr/statistics/update?commit=true'">http://localhost:8081/solr/statistics/update?commit=true'</a>

<pre><code>
- So the blocking seems to be working because &quot;www\.gnip\.com&quot; is one of the new patterns added to the spiders file...
## 2019-11-07
- CCAFS finally confirmed that they do indeed need the confusing new project tag that looks like a duplicate
- They had proposed a batch of new tags in 2019-09 and we never merged them due to this uncertainty
- I have now merged the changes in to the `5_x-prod` branch ([#432](https://github.com/ilri/DSpace/pull/432))
- I am reconsidering the move of `cg.identifier.dataurl` to `cg.hasMetadata` in CG Core v2
- The values of this field are mostly links to data sets on Dataverse and partner sites
- I opened an [issue on GitHub](https://github.com/AgriculturalSemantics/cg-core/issues/10) to ask Marie-Angelique for clarification
- Looking into CGSpace statistics again
- I searched for hits in Solr from the BUbiNG bot and found 63,000 in the `statistics-2018` core:

- I wrote a quick bash script to check all these user agents against the CGSpace Solr statistics cores
- For years 2010 until 2019 there are 1.6 million hits from these spider user agents
- For 2019 alone there are 740,000, over half of which come from Unpaywall!
- Looking at the facets I see there were about 200,000 hits from Unpaywall in 2019-10:

- That answers Peter's question about why the stats jumped in October...
## 2019-11-08
- I saw a bunch of user agents that have the literal string `User-Agent` in their user agent HTTP header, for example:
- `User-Agent: Drupal (+http://drupal.org/)`
- `User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.31 (KHTML, like Gecko) Chrome/26.0.1410.64 Safari/537.31`
- `User-Agent:Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; Trident/6.0) IKU/7.0.5.9226;IKUCID/IKU;`
- `User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; 360SE)`
- `User-Agent:User-Agent:Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; GTB7.5; .NET4.0C)IKU/6.7.6.12189;IKUCID/IKU;IKU/6.7.6.12189;IKUCID/IKU;`
- `User-Agent:Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; WOW64; Trident/6.0) IKU/7.0.5.9226;IKUCID/IKU;`
- I filed [an issue](https://github.com/atmire/COUNTER-Robots/issues/27) on the COUNTER-Robots project to see if they agree to add `User-Agent:` to the list of robot user agents
## 2019-11-09
- Deploy the latest `5_x-prod` branch on CGSpace (linode19)
- This includes the updated CCAFS phase II project tags and the updated spider user agents
- Run all system updates on CGSpace and reboot the server
- After rebooting it seems that all Solr statistics cores came back up fine...
- I did some work to clean up my bot processing script and removed about 2 million hits from the statistics cores on CGSpace
- The script is called `check-spider-hits.sh`
- After a bunch of tests and checks I ran it for each statistics shard like so:
</code></pre>
<p>$ for shard in statistics statistics-2018 statistics-2017 statistics-2016 statistics-2015 stat

<pre><code>
- Open a [pull request](https://github.com/atmire/COUNTER-Robots/pull/28) against COUNTER-Robots to remove unnecessary escaping of dashes
## 2019-11-12
- Udana and Chandima emailed me to ask why [one of their WLE items](https://hdl.handle.net/10568/81236) that is mapped from IWMI only shows up in the IWMI &quot;department&quot; on the Altmetric dashboard
- A [search in the IWMI department shows the item](https://www.altmetric.com/explorer/outputs?department_id%5B%5D=CGSpace%3Agroup%3Acom_10568_16814&amp;q=Towards%20sustainable%20sanitation%20management)
- A [search in the WLE department shows no results](https://www.altmetric.com/explorer/outputs?department_id%5B%5D=CGSpace%3Agroup%3Acom_10568_34494&amp;q=Towards%20sustainable%20sanitation%20management)
- I emailed Altmetric support to ask for help
- Also, while analysing this, I looked through some of the other top WLE items and fixed some metadata issues (adding `dc.rights`, fixing DOIs, adding ISSNs, etc) and noticed one issue with [an item](https://hdl.handle.net/10568/97087) that has an Altmetric score for its Handle (lower) despite it having a correct DOI (with a higher score)
- I tweeted the Handle to see if the score would get linked once Altmetric noticed it
## 2019-11-13
- The [item with a low Altmetric score for its Handle](https://hdl.handle.net/10568/97087) that I tweeted yesterday still hasn't linked with the DOI's score
- I tweeted it again with the Handle and the DOI
- Testing modifying some of the COUNTER-Robots patterns to use `[0-9]` instead of `\d` digit character type, as Solr's regex search can't use those

- Nice, so searching with regex in Solr with `//` syntax works for those digits!
- I realized that it's easier to search Solr from curl via POST using this syntax:
</code></pre>
<p>$ curl -s &ldquo;<a href="http://localhost:8081/solr/statistics/select&quot;">http://localhost:8081/solr/statistics/select&quot;</a> -d &ldquo;q=userAgent:<em>Scrapoo</em>&amp;rows=0&rdquo;)</p>
<pre><code>
- If the parameters include something like &quot;[0-9]&quot; then curl interprets it as a range and will make ten requests
- You can disable this using the `-g` option, but there are other benefits to searching with POST, for example it seems that I have less issues with escaping special parameters when using Solr's regex search:
</code></pre>
<p>$ curl -s &lsquo;<a href="http://localhost:8081/solr/statistics/select'">http://localhost:8081/solr/statistics/select'</a> -d &lsquo;q=userAgent:/Postgenomic(\s|+)v2/&amp;rows=2&rsquo;</p>
<pre><code>
- I updated the `check-spider-hits.sh` script to use the POST syntax, and I'm evaluating the feasability of including the regex search patterns from the spider agent file, as I had been filtering them out due to differences in PCRE and Solr regex syntax and issues with shell handling
## 2019-11-14
- IWMI sent a few new ORCID identifiers for us to add to our controlled vocabulary
- I will merge them with our existing list and then resolve their names using my `resolve-orcids.py` script:
</code></pre>
<p>$ cat ~/src/git/DSpace/dspace/config/controlled-vocabularies/cg-creator-id.xml /tmp/iwmi-orcids.txt | grep -oE &lsquo;[A-Z0-9]{4}-[A-Z0-9]{4}-[A-Z0-9]{4}-[A-Z0-9]{4}&rsquo; | sort | uniq &gt; /tmp/2019-11-14-combined-orcids.txt
$ ./resolve-orcids.py -i /tmp/2019-11-14-combined-orcids.txt -o /tmp/2019-11-14-combined-names.txt -d</p>
<h1 id="sort-names-copy-to-cg-creator-id-xml-add-xml-formatting-and-then-format-with-tidy-preserving-accents">sort names, copy to cg-creator-id.xml, add XML formatting, and then format with tidy (preserving accents)</h1>
<p>$ tidy -xml -utf8 -iq -m -w 0 dspace/config/controlled-vocabularies/cg-creator-id.xml</p>
<pre><code>
- I created a [pull request](https://github.com/ilri/DSpace/pull/437) and merged them into the `5_x-prod` branch
- I will deploy them to CGSpace in the next few days
- Greatly improve my `check-spider-hits.sh` script to handle regular expressions in the spider agents patterns file
- This allows me to detect and purge many more hits from the Solr statistics core
- I've tested it quite a bit on DSpace Test, but I need to do a little more before I feel comfortable running the new code on CGSpace's Solr cores
## 2019-11-15
- Run the new version of `check-spider-hits.sh` on CGSpace's Solr statistics cores one by one, starting from the oldest just in case something goes wrong
- But then I noticed that some (all?) of the hits weren't actually getting purged, all of which were using regular expressions like:
- `MetaURI[\+\s]API\/[0-9]\.[0-9]`
- `FDM(\s|\+)[0-9]`
- `Goldfire(\s|\+)Server`
- `^Mozilla\/4\.0\+\(compatible;\)$`
- `^Mozilla\/4\.0\+\(compatible;\+ICS\)$`
- `^Mozilla\/4\.5\+\[en]\+\(Win98;\+I\)$`
- Upon closer inspection, the plus signs seem to be getting misinterpreted somehow in the delete, but not in the select!
- Plus signs are special in regular expressions, URLs, and Solr's Lucene query parser, so I'm actually not sure where the issue is
- I tried to do URL encoding of the +, double escaping, etc... but nothing worked
- I'm going to ignore regular expressions that have pluses for now
- I think I might also have to ignore patterns that have percent signs, like `^\%?default\%?$`
- After I added the ignores and did some more testing I finally ran the `check-spider-hits.sh` on all CGSpace Solr statistics cores and these are the number of hits purged from each core:
- statistics-2010: 113
- statistics-2011: 7235
- statistics-2012: 0
- statistics-2013: 0
- statistics-2014: 316
- statistics-2015: 16809
- statistics-2016: 41732
- statistics-2017: 39207
- statistics-2018: 295546
- statistics: 1043373
- That's 1.4 million hits in addition to the 2 million I purged earlier this week...
- For posterity, the major contributors to the hits on the statistics core were:
- Purging 812429 hits from curl\/ in statistics
- Purging 48206 hits from facebookexternalhit\/ in statistics
- Purging 72004 hits from PHP\/ in statistics
- Purging 76072 hits from Yeti\/[0-9] in statistics
- Most of the curl hits were from CIAT in mid-2019, where they were using [GuzzleHttp](https://guzzle3.readthedocs.io/http-client/client.html) from PHP, which uses something like this for its user agent:
</code></pre>
<p>Guzzle/<Guzzle_Version> curl/<curl_version> PHP/<PHP_VERSION>
