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;

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

</code></pre>

<p>$ http &ndash;print b &lsquo;<a href="http://localhost:8081/solr/statistics/select?q=(ip%3A34.224.4.16+OR+ip%3A34.234.204.152)&amp;rows=0&amp;wt=json&amp;indent=true'">http://localhost:8081/solr/statistics/select?q=(ip%3A34.224.4.16+OR+ip%3A34.234.204.152)&amp;rows=0&amp;wt=json&amp;indent=true'</a></p>

<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):

</code></pre>

<p>$ http &ndash;print Hh &lsquo;<a href="https://dspacetest.cgiar.org/handle/10568/1/discover'">https://dspacetest.cgiar.org/handle/10568/1/discover'</a> User-Agent:&ldquo;Amazonbot/0.1&rdquo;</p>

<pre><code>
- 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;
$ 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;
$ http &ndash;print Hh &lsquo;<a href="https://dspacetest.cgiar.org/bitstream/handle/10568/105487/csl_Crane_oct2019.pptx?sequence=1&amp;isAllowed=y'">https://dspacetest.cgiar.org/bitstream/handle/10568/105487/csl_Crane_oct2019.pptx?sequence=1&amp;isAllowed=y'</a> User-Agent:&ldquo;iskanie&rdquo;</p>

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

</code></pre>

<p>$ http &ndash;print b &lsquo;<a href="http://localhost:8081/solr/statistics/select?q=ip:73.178.9.24+AND+userAgent:iskanie&amp;fq=dateYearMonth%3A2019-11&amp;rows=0'">http://localhost:8081/solr/statistics/select?q=ip:73.178.9.24+AND+userAgent:iskanie&amp;fq=dateYearMonth%3A2019-11&amp;rows=0'</a>

<pre><code>
- 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>
$ http &ndash;print b &lsquo;<a href="http://localhost:8081/solr/statistics/select?q=userAgent:alanfuuu1&amp;fq=dateYearMonth%3A2019-11'">http://localhost:8081/solr/statistics/select?q=userAgent:alanfuuu1&amp;fq=dateYearMonth%3A2019-11'</a> | xmllint &ndash;format - | grep numFound
  <result name="response" numFound="1" start="0">
$ http &ndash;print b &lsquo;<a href="http://localhost:8081/solr/statistics/select?q=userAgent:alanfuuu2&amp;fq=dateYearMonth%3A2019-11'">http://localhost:8081/solr/statistics/select?q=userAgent:alanfuuu2&amp;fq=dateYearMonth%3A2019-11'</a> | xmllint &ndash;format - | grep numFound
  <result name="response" numFound="0" start="0"/></p>

<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:

</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;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>
$ http &ndash;print b &lsquo;<a href="http://localhost:8081/solr/statistics/select?q=userAgent:www.gnip.com&amp;fq=dateYearMonth%3A2019-11'">http://localhost:8081/solr/statistics/select?q=userAgent:www.gnip.com&amp;fq=dateYearMonth%3A2019-11'</a> | xmllint &ndash;format - | grep numFound
  <result name="response" numFound="0" start="0"/>
$ http &ndash;print b &lsquo;<a href="http://localhost:8081/solr/statistics/select?q=userAgent:www.gnyp.com&amp;fq=dateYearMonth%3A2019-11'">http://localhost:8081/solr/statistics/select?q=userAgent:www.gnyp.com&amp;fq=dateYearMonth%3A2019-11'</a> | xmllint &ndash;format - | grep numFound
  <result name="response" numFound="1" start="0"></p>

<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:

  - 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:

- 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>

<ul>
<li>I updated the <code>check-spider-hits.sh</code> script to use the POST syntax, and I&rsquo;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</li>
</ul>
