- Meeting with AgroKnow to discuss CGSpace, ILRI data, AReS, GARDIAN, etc
- They asked if we had plans to enable RDF support in CGSpace
- There have been 4,400 more downloads of the CTA Spore publication from those strange Amazon IP addresses today
- I suspected that some might not be successful, because the stats show less, but today they were all HTTP 200!
# cat /var/log/nginx/access.log /var/log/nginx/access.log.1 | grep 'Spore-192-EN-web.pdf' | grep -E '(18.196.196.108|18.195.78.144|18.195.218.6)' | awk '{print $9}' | sort | uniq -c | sort -n | tail -n 5
4432 200
- In the last two weeks there have been 47,000 downloads of this same exact PDF by these three IP addresses
- Apply country and region corrections and deletions on DSpace Test and CGSpace:
$ ./fix-metadata-values.py -i /tmp/2019-02-21-fix-9-countries.csv -db dspace -u dspace -p 'fuuu' -f cg.coverage.country -m 228 -t ACTION -d

- CTA says the Amazon IPs are AWS gateways for real user traffic
- I was trying to add Felix Shaw's account back to the Administrators group on DSpace Test, but I couldn't find his name in the user search of the groups page
- If I searched for "Felix" or "Shaw" I saw other matches, included one for his personal email address!
- I ended up finding him via searching for his email address
2019-04-03
- Maria from Bioversity emailed me a list of new ORCID identifiers for their researchers so I will add them to our controlled vocabulary
- First I need to extract the ones that are unique from their list compared to our existing one:
$ cat dspace/config/controlled-vocabularies/cg-creator-id.xml /tmp/bioversity.txt | grep -oE '[A-Z0-9]{4}-[A-Z0-9]{4}-[A-Z0-9]{4}-[A-Z0-9]{4}' | sort -u > /tmp/2019-04-03-orcid-ids.txt
- We currently have 1177 unique ORCID identifiers, and this brings our total to 1237!
- Next I will resolve all their names using my
resolve-orcids.pyscript:
$ ./resolve-orcids.py -i /tmp/2019-04-03-orcid-ids.txt -o 2019-04-03-orcid-ids.txt -d
- After that I added the XML formatting, formatted the file with tidy, and sorted the names in vim
- One user's name has changed so I will update those using my
fix-metadata-values.pyscript:
$ ./fix-metadata-values.py -i 2019-04-03-update-orcids.csv -db dspace -u dspace -p 'fuuu' -f cg.creator.id -m 240 -t correct -d
- I created a pull request and merged the changes to the 5_x-prod branch (#417)
- A few days ago I noticed some weird update process for the statistics-2018 Solr core and I see it's still going:
2019-04-03 16:34:02,262 INFO org.dspace.statistics.SolrLogger @ Updating : 1754500/21701 docs in http://localhost:8081/solr//statistics-2018
- Interestingly, there are 5666 occurences, and they are mostly for the 2018 core:
$ grep 'org.dspace.statistics.SolrLogger @ Updating' /home/cgspace.cgiar.org/log/dspace.log.2019-04-03 | awk '{print $11}' | sort | uniq -c
1
3 http://localhost:8081/solr//statistics-2017
5662 http://localhost:8081/solr//statistics-2018
- I will have to keep an eye on it because nothing should be updating 2018 stats in 2019...
2019-04-05
- Uptime Robot reported that CGSpace (linode18) went down tonight
- I see there are lots of PostgreSQL connections:
$ psql -c 'select * from pg_stat_activity' | grep -o -E '(dspaceWeb|dspaceApi|dspaceCli)' | sort | uniq -c
5 dspaceApi
10 dspaceCli
250 dspaceWeb
- I still see those weird messages about updating the statistics-2018 Solr core:
2019-04-05 21:06:53,770 INFO org.dspace.statistics.SolrLogger @ Updating : 2444600/21697 docs in http://localhost:8081/solr//statistics-2018
- Looking at
iostat 1 10I also see some CPU steal has come back, and I can confirm it by looking at the Munin graphs:
- The other thing visible there is that the past few days the load has spiked to 500% and I don't think it's a coincidence that the Solr updating thing is happening...
- I ran all system updates and rebooted the server
- The load was lower on the server after reboot, but Solr didn't come back up properly according to the Solr Admin UI:
statistics-2017: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error opening new searcher
- I restarted it again and all the Solr cores came up properly...
2019-04-06
- Udana asked why item 10568/91278 didn't have an Altmetric badge on CGSpace, but on the WLE website it does
- I looked and saw that the WLE website is using the Altmetric score associated with the DOI, and that the Handle has no score at all
- I tweeted the item and I assume this will link the Handle with the DOI in the system
- Twenty minutes later I see the same Altmetric score (9) on CGSpace
- Linode sent an alert that there was high CPU usage this morning on CGSpace (linode18) and these were the top IPs in the webserver access logs around the time:

45.5.184.72is in Colombia so it's probably CIAT, and I see they are indeed trying to get crawl the Discover pages on CIAT's datasets collection:
GET /handle/10568/72970/discover?filtertype_0=type&filtertype_1=author&filter_relational_operator_1=contains&filter_relational_operator_0=equals&filter_1=&filter_0=Dataset&filtertype=dateIssued&filter_relational_operator=equals&filter=2014
- Their user agent is the one I added to the badbots list in nginx last week: "GuzzleHttp/6.3.3 curl/7.47.0 PHP/7.0.30-0ubuntu0.16.04.1"
- They made 22,000 requests to Discover on this collection today alone (and it's only 11AM):
# cat /var/log/nginx/access.log /var/log/nginx/access.log.1 | grep "06/Apr/2019" | grep 45.5.184.72 | grep -oE '/handle/[0-9]+/[0-9]+/discover' | sort | uniq -c
22077 /handle/10568/72970/discover
- Yesterday they made 43,000 requests and we actually blocked most of them:
# zcat --force /var/log/nginx/access.log /var/log/nginx/access.log.1 /var/log/nginx/access.log.2.gz | grep "05/Apr/2019" | grep 45.5.184.72 | grep -oE '/handle/[0-9]+/[0-9]+/discover' | sort | uniq -c

43489 503
- I need to find a contact at CIAT to tell them to use the REST API rather than crawling Discover
- Maria from Bioversity recommended that we use the phrase "AGROVOC subject" instead of "Subject" in Listings and Reports
- I made a pull request to update this and merged it to the
5_x-prodbranch (#418)
- I made a pull request to update this and merged it to the
2019-04-07
- Looking into the impact of harvesters like
45.5.184.72, 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 per day - Last week CTA switched their frontend code to use HEAD requests instead of GET requests for bitstreams
- I am trying to see if these are registered as downloads in Solr or not
- I see 96,925 downloads from their AWS gateway IPs in 2019-03:
$ http --print b 'http://localhost:8081/solr/statistics/select?q=type%3A0+AND+(ip%3A18.196.196.108+OR+ip%3A18.195.78.144+OR+ip%3A18.195.218.6)&fq=statistics_type%3Aview&fq=bundleName%3AORIGINAL&fq=dateYearMonth%3A2019-03&rows=0&wt=json&indent=true'

- Strangely I don't see many hits in 2019-04:

- Making some tests on GET vs HEAD requests on the CTA Spore 192 item on DSpace Test:

- And from the server side, the nginx logs show:
78.x.x.x - - [07/Apr/2019:01:38:35 -0700] "GET /bitstream/handle/10568/100289/Spore-192-EN-web.pdf HTTP/1.1" 200 68078 "-" "HTTPie/1.0.2"
78.x.x.x - - [07/Apr/2019:01:39:01 -0700] "HEAD /bitstream/handle/10568/100289/Spore-192-EN-web.pdf HTTP/1.1" 200 0 "-" "HTTPie/1.0.2"
- So definitely the size of the transfer is more efficient with a HEAD, but I need to wait to see if these requests show up in Solr
- 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:
2019-04-07 02:05:30,966 INFO org.dspace.usage.LoggerUsageEventListener @ anonymous:session_id=EF2DB6E4F69926C5555B3492BB0071A8:ip_addr=78.x.x.x:view_bitstream:bitstream_id=165818
2019-04-07 02:05:39,265 INFO org.dspace.usage.LoggerUsageEventListener @ anonymous:session_id=B6381FC590A5160D84930102D068C7A3:ip_addr=78.x.x.x:view_bitstream:bitstream_id=165818
- So my inclination is that both HEAD and GET requests are registered as views as far as Solr and DSpace are concerned
- 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:
2019-04-07 02:08:44,186 INFO org.apache.solr.update.UpdateHandler @ start commit{,optimize=true,openSearcher=true,waitSearcher=true,expungeDeletes=false,softCommit=false,prepareCommit=false}
- 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
statistics_type:view... very weird- 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)
- I will try to re-deploy the
5_x-devbranch and test again
- According to the DSpace 5.x Solr documentation the default commit time is after 15 minutes or 10,000 documents (see
solrconfig.xml) - I looped some GET and HEAD requests to a bitstream on my local instance and after some time I see that they do register as downloads (even though they are internal):
$ http --print b 'http://localhost:8080/solr/statistics/select?q=type%3A0+AND+time%3A2019-04-07*&fq=statistics_type%3Aview&fq=isInternal%3Atrue&rows=0&wt=json&indent=true'
{
"response": {
"docs": [],
"numFound": 909,
"start": 0
},
"responseHeader": {
"QTime": 0,
"params": {
"fq": [
"statistics_type:view",
"isInternal:true"
],
"indent": "true",
"q": "type:0 AND time:2019-04-07*",
"rows": "0",
"wt": "json"
},
"status": 0
}
}
- I confirmed the same on CGSpace itself after making one HEAD request
- 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
- 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
- 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
- This leads me to believe there is something specifically wrong with DSpace Test (linode19)
- The only thing I can think of is that the JVM is using G1GC instead of ConcMarkSweepGC
- Holy shit, all this is actually because of the GeoIP1 deprecation and a missing
GeoLiteCity.dat- For some reason the missing GeoIP data causes stats to not be recorded whatsoever and there is no error!
- See: DS-3986
- See: DS-4020
- See: DS-3832
- 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 removed from MaxMind's server as of 2018-04-01
- Now I made 100 requests and I see them in the Solr statistics... fuck my life for wasting five hours debugging this
- UptimeRobot said CGSpace went down and up a few times tonight, and my first instict was to check
iostat 1 10and I saw that CPU steal is around 10–30 percent right now... - The load average is super high right now, as I've noticed the last few times UptimeRobot said that CGSpace went down:
$ cat /proc/loadavg
10.70 9.17 8.85 18/633 4198
- According to the server logs there is actually not much going on right now:

- It seems that the issue with CGSpace being "down" is actually because of CPU steal again!!!
- I opened a ticket with support and asked them to migrate the VM to a less busy host
