--- title: "November, 2017" date: 2017-11-02T09:37:54+02:00 author: "Alan Orth" tags: ["Notes"] --- ## 2017-11-01 - The CORE developers responded to say they are looking into their bot not respecting our robots.txt ## 2017-11-02 - Today there have been no hits by CORE and no alerts from Linode (coincidence?) ``` # grep -c "CORE" /var/log/nginx/access.log 0 ``` - Generate list of authors on CGSpace for Peter to go through and correct: ``` dspace=# \copy (select distinct text_value, count(*) as count from metadatavalue where metadata_field_id = (select metadata_field_id from metadatafieldregistry where element = 'contributor' and qualifier = 'author') AND resource_type_id = 2 group by text_value order by count desc) to /tmp/authors.csv with csv; COPY 54701 ``` - Abenet asked if it would be possible to generate a report of items in Listing and Reports that had "International Fund for Agricultural Development" as the *only* investor - I opened a ticket with Atmire to ask if this was possible: https://tracker.atmire.com/tickets-cgiar-ilri/view-ticket?id=540 - Work on making the thumbnails in the item view clickable - Basically, once you read the METS XML for an item it becomes easy to trace the structure to find the bitstream link ``` //mets:fileSec/mets:fileGrp[@USE='CONTENT']/mets:file/mets:FLocat[@LOCTYPE='URL']/@xlink:href ``` - METS XML is available for all items with this pattern: /metadata/handle/10568/95947/mets.xml - I whipped up a quick hack to print a clickable link with this URL on the thumbnail but it needs to check a few corner cases, like when there is a thumbnail but no content bitstream! - Help proof fifty-three CIAT records for Sisay: https://dspacetest.cgiar.org/handle/10568/95895 - A handful of issues with `cg.place` using format like "Lima, PE" instead of "Lima, Peru" - Also, some dates like with completely invalid format like "2010- 06" and "2011-3-28" - I also collapsed some consecutive whitespace on a handful of fields ## 2017-11-03 - Atmire got back to us to say that they estimate it will take two days of labor to implement the change to Listings and Reports - I said I'd ask Abenet if she wants that feature ## 2017-11-04 - I finished looking through Sisay's CIAT records for the "Alianzas de Aprendizaje" data - I corrected about half of the authors to standardize them - Linode emailed this morning to say that the CPU usage was high again, this time at 6:14AM - It's the first time in a few days that this has happened - I had a look to see what was going on, but it isn't the CORE bot: ``` # awk '{print $1}' /var/log/nginx/access.log | sort -n | uniq -c | sort -h | tail 306 68.180.229.31 323 61.148.244.116 414 66.249.66.91 507 40.77.167.16 618 157.55.39.161 652 207.46.13.103 666 157.55.39.254 1173 104.196.152.243 1737 66.249.66.90 23101 138.201.52.218 ``` - 138.201.52.218 is from some Hetzner server, and I see it making 40,000 requests yesterday too, but none before that: ``` # zgrep -c 138.201.52.218 /var/log/nginx/access.log* /var/log/nginx/access.log:24403 /var/log/nginx/access.log.1:45958 /var/log/nginx/access.log.2.gz:0 /var/log/nginx/access.log.3.gz:0 /var/log/nginx/access.log.4.gz:0 /var/log/nginx/access.log.5.gz:0 /var/log/nginx/access.log.6.gz:0 ``` - It's clearly a bot as it's making tens of thousands of requests, but it's using a "normal" user agent: ``` Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2227.0 Safari/537.36 ``` - For now I don't know what this user is! ## 2017-11-05 - Peter asked if I could fix the appearance of "International Livestock Research Institute" in the author lookup during item submission - It looks to be just an issue with the user interface expecting authors to have both a first and last name: ![Author lookup](/cgspace-notes/2017/11/author-lookup.png) ![Add author](/cgspace-notes/2017/11/add-author.png) - But in the database the authors are correct (none with weird `, /` characters): ``` dspace=# select distinct text_value, authority, confidence from metadatavalue value where resource_type_id=2 and metadata_field_id=3 and text_value like 'International Livestock Research Institute%'; text_value | authority | confidence --------------------------------------------+--------------------------------------+------------ International Livestock Research Institute | 8f3865dc-d056-4aec-90b7-77f49ab4735c | 0 International Livestock Research Institute | f4db1627-47cd-4699-b394-bab7eba6dadc | 0 International Livestock Research Institute | | -1 International Livestock Research Institute | 8f3865dc-d056-4aec-90b7-77f49ab4735c | 600 International Livestock Research Institute | f4db1627-47cd-4699-b394-bab7eba6dadc | -1 International Livestock Research Institute | | 600 International Livestock Research Institute | 8f3865dc-d056-4aec-90b7-77f49ab4735c | -1 International Livestock Research Institute | 8f3865dc-d056-4aec-90b7-77f49ab4735c | 500 (8 rows) ``` - So I'm not sure if this is just a graphical glitch or if editors have to edit this metadata field prior to approval - Looking at monitoring Tomcat's JVM heap with Prometheus, it looks like we need to use JMX + [jmx_exporter](https://github.com/prometheus/jmx_exporter) - This guide shows how to [enable JMX in Tomcat](https://geekflare.com/enable-jmx-tomcat-to-monitor-administer/) by modifying `CATALINA_OPTS` - I was able to successfully connect to my local Tomcat with jconsole!
