- 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.py
script:
$ ./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.py
script:
$ ./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 10
I 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:

is 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

142 200
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-prod
branch (#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-dev
branch 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 10
and 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:

is CIAT, who I already blocked and am waiting to hear from2a01:4f8:140:3192::2
is BLEXbot, which should be handled by the Tomcat Crawler Session Manager Valve2408:8214:7a00:868f:7c1e:e0f3:20c6:c142
is some stupid Chinese bot making malicious POST requests- There are free database connections in the pool:
$ psql -c 'select * from pg_stat_activity' | grep -o -E '(dspaceWeb|dspaceApi|dspaceCli)' | sort | uniq -c
5 dspaceApi
7 dspaceCli
23 dspaceWeb
- 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
2019-04-08
- Start checking IITA's last round of batch uploads from March on DSpace Test (20193rd.xls)
- Lots of problems with affiliations, I had to correct about sixty of them
- I used lein to host the latest CSV of our affiliations for OpenRefine to reconcile against:
$ lein run ~/src/git/DSpace/2019-02-22-affiliations.csv name id
- After matching the values and creating some new matches I had trouble remembering how to copy the reconciled values to a new column
- The matched values can be accessed with
cell.recon.match.name
, but some of the new values don't appear, perhaps because I edited the original cell values? - I ended up using this GREL expression to copy all values to a new column:
- The matched values can be accessed with
if(cell.recon.matched, cell.recon.match.name, value)
- See the OpenRefine variables documentation for more notes about the
recon
object - I also noticed a handful of errors in our current list of affiliations so I corrected them:
$ ./fix-metadata-values.py -i 2019-04-08-fix-13-affiliations.csv -db dspace -u dspace -p 'fuuu' -f cg.contributor.affiliation -m 211 -t correct -d
- We should create a new list of affiliations to update our controlled vocabulary again
- I dumped a list of the top 1500 affiliations:
dspace=# \COPY (SELECT DISTINCT text_value, count(*) FROM metadatavalue WHERE metadata_field_id = 211 AND resource_type_id = 2 GROUP BY text_value ORDER BY count DESC LIMIT 1500) to /tmp/2019-04-08-top-1500-affiliations.csv WITH CSV HEADER;
COPY 1500
- Fix a few more messed up affiliations that have return characters in them (use Ctrl-V Ctrl-M to re-create control character):
dspace=# UPDATE metadatavalue SET text_value='International Institute for Environment and Development' WHERE resource_type_id = 2 AND metadata_field_id = 211 AND text_value LIKE 'International Institute^M%';
dspace=# UPDATE metadatavalue SET text_value='Kenya Agriculture and Livestock Research Organization' WHERE resource_type_id = 2 AND metadata_field_id = 211 AND text_value LIKE 'Kenya Agricultural and Livestock Research^M%';
- I noticed a bunch of subjects and affiliations that use stylized apostrophes so I will export those and then batch update them:
dspace=# \COPY (SELECT DISTINCT text_value FROM metadatavalue WHERE resource_type_id = 2 AND metadata_field_id = 211 AND text_value LIKE '%’%') to /tmp/2019-04-08-affiliations-apostrophes.csv WITH CSV HEADER;
COPY 60
dspace=# \COPY (SELECT DISTINCT text_value FROM metadatavalue WHERE resource_type_id = 2 AND metadata_field_id = 57 AND text_value LIKE '%’%') to /tmp/2019-04-08-subject-apostrophes.csv WITH CSV HEADER;
COPY 20
- I cleaned them up in OpenRefine and then applied the fixes on CGSpace and DSpace Test:
$ ./fix-metadata-values.py -i /tmp/2019-04-08-fix-60-affiliations-apostrophes.csv -db dspace -u dspace -p 'fuuu' -f cg.contributor.affiliation -m 211 -t correct -d

- UptimeRobot said that CGSpace (linode18) went down tonight
- The load average is at
9.42, 8.87, 7.87
- I looked at PostgreSQL and see shitloads of connections there:
- The load average is at
$ psql -c 'select * from pg_stat_activity' | grep -o -E '(dspaceWeb|dspaceApi|dspaceCli)' | sort | uniq -c
5 dspaceApi
7 dspaceCli
250 dspaceWeb
- On a related note I see connection pool errors in the DSpace log:
2019-04-08 19:01:10,472 ERROR org.dspace.storage.rdbms.DatabaseManager @ SQL connection Error -
org.apache.tomcat.jdbc.pool.PoolExhaustedException: [http-bio-127.0.0.1-8443-exec-319] Timeout: Pool empty. Unable to fetch a connection in 5 seconds, none available[size:250; busy:250; idle:0; lastwait:5000].
- But still I see 10 to 30% CPU steal in
iostat
that is also reflected in the Munin graphs:
- Linode Support still didn't respond to my ticket from yesterday, so I attached a new output of
iostat 1 10
and asked them to move the VM to a less busy host - The web server logs are not very busy:

is at CIAT in Colombia and I see they are mostly making requests to the REST API, but also to XMLUI with the following user agent:
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.103 Safari/537.36
- Database connection usage looks fine:
$ psql -c 'select * from pg_stat_activity' | grep -o -E '(dspaceWeb|dspaceApi|dspaceCli)' | sort | uniq -c
5 dspaceApi
7 dspaceCli
11 dspaceWeb
- Ironically I do still see some 2 to 10% of CPU steal in
iostat 1 10
- Leroy from CIAT contacted me to say he knows the team who is making all those requests to CGSpace
- I told them how to use the REST API to get the CIAT Datasets collection and enumerate its items
- In other news, Linode staff identified a noisy neighbor sharing our host and migrated it elsewhere last night
2019-04-10
- Abenet pointed out a possibility of validating funders against the CrossRef API
- Note that if you use HTTPS and specify a contact address in the API request you have less likelihood of being blocked
$ http 'https://api.crossref.org/funders?query=mercator&mailto=me@cgiar.org'
- Otherwise, they provide the funder data in CSV and RDF format
- I did a quick test with the recent IITA records against reconcile-csv in OpenRefine and it matched a few, but the ones that didn't match will need a human to go and do some manual checking and informed decision making...
- If I want to write a script for this I could use the Python habanero library:
from habanero import Crossref
cr = Crossref(mailto="me@cgiar.org")
x = cr.funders(query = "mercator")
2019-04-11
- Continue proofing IITA's last round of batch uploads from March on DSpace Test (20193rd.xls)
- One misspelled country
- Three incorrect regions
- Potential duplicates (same DOI, similar title, same authors):
- Two DOIs with incorrect URL formatting
- Two misspelled IITA subjects
- Two authors with smart quotes
- Lots of issues with sponsors
- One misspelled "Peer review"
- One invalid ISBN that I fixed by Googling the title
- Lots of issues with sponsors (German Aid Agency, Swiss Aid Agency, Italian Aid Agency, Dutch Aid Agency, etc)
- I validated all the AGROVOC subjects against our latest list with reconcile-csv
- About 720 of the 900 terms were matched, then I checked and fixed or deleted the rest manually
- I captured a few general corrections and deletions for AGROVOC subjects while looking at IITA's records, so I applied them to DSpace Test and CGSpace:
$ ./fix-metadata-values.py -i /tmp/2019-04-11-fix-14-subjects.csv -db dspace -u dspace -p 'fuuu' -f dc.subject -m 57 -t correct -d
$ ./delete-metadata-values.py -i /tmp/2019-04-11-delete-6-subjects.csv -db dspace -u dspace -p 'fuuu' -m 57 -f dc.subject -d
- Answer more questions about DOIs and Altmetric scores from WLE
- Answer more questions about DOIs and Altmetric scores from IWMI
- They can't seem to understand the Altmetric + Twitter flow for associating Handles and DOIs
- To make things worse, many of their items DON'T have DOIs, so when Altmetric harvests them of course there is no link! - Then, a bunch of their items don't have scores because they never tweeted them!
- They added a DOI to this old item 10567/97087 this morning and wonder why Altmetric's score hasn't linked with the DOI magically
- We should check in a week to see if Altmetric will make the association after one week when they harvest again
2019-04-13
- I copied the
statistics
andstatistics-2018
Solr cores from CGSpace to my local machine and watched the Java process in VisualVM while indexing item views and downloads with my dspace-statistics-api:
- It took about eight minutes to index 784 pages of item views and 268 of downloads, and you can see a clear "sawtooth" pattern in the garbage collection
- I am curious if the GC pattern would be different if I switched from the
-XX:+UseConcMarkSweepGC
to G1GC - I switched to G1GC and restarted Tomcat but for some reason I couldn't see the Tomcat PID in VisualVM...
- Anyways, the indexing process took much longer, perhaps twice as long!
- I tried again with the GC tuning settings from the Solr 4.10.4 release:
2019-04-14
- Change DSpace Test (linode19) to use the Java GC tuning from the Solr 4.10.4 startup script:
GC_TUNE="-XX:NewRatio=3 \
-XX:SurvivorRatio=4 \
-XX:TargetSurvivorRatio=90 \
-XX:MaxTenuringThreshold=8 \
-XX:+UseConcMarkSweepGC \
-XX:+UseParNewGC \
-XX:ConcGCThreads=4 -XX:ParallelGCThreads=4 \
-XX:+CMSScavengeBeforeRemark \
-XX:PretenureSizeThreshold=64m \
-XX:+UseCMSInitiatingOccupancyOnly \
-XX:CMSInitiatingOccupancyFraction=50 \
-XX:CMSMaxAbortablePrecleanTime=6000 \
-XX:+CMSParallelRemarkEnabled \
-XX:+ParallelRefProcEnabled"
- I need to remember to check the Munin JVM graphs in a few days
- It might be placebo, but the site does feel snappier...
2019-04-15
- Rework the dspace-statistics-api to use the vanilla Python requests library instead of Solr client
- Tag version 1.0.0 and deploy it on DSpace Test
- Pretty annoying to see CGSpace (linode18) with 20–50% CPU steal according to
iostat 1 10
, though I haven't had any Linode alerts in a few days - Abenet sent me a list of ILRI items that don't have CRPs added to them
- The spreadsheet only had Handles (no IDs), so I'm experimenting with using Python in OpenRefine to get the IDs
- I cloned the handle column and then did a transform to get the IDs from the CGSpace REST API:
import json
import re
import urllib
import urllib2
handle = re.findall('[0-9]+/[0-9]+', value)
url = 'https://cgspace.cgiar.org/rest/handle/' + handle[0]
req = urllib2.Request(url)
req.add_header('User-agent', 'Alan Python bot')
res = urllib2.urlopen(req)
data = json.load(res)
item_id = data['id']
return item_id
- Luckily none of the items already had CRPs, so I didn't have to worry about them getting removed
- It would have been much trickier if I had to get the CRPs for the items first, then add the CRPs...
- I ran a full Discovery indexing on CGSpace because I didn't do it after all the metadata updates last week:
$ time schedtool -B -e ionice -c2 -n7 nice -n19 dspace index-discovery -b
real 82m45.324s
user 7m33.446s
sys 2m13.463s
2019-04-16
- Export IITA's community from CGSpace because they want to experiment with importing it into their internal DSpace for some testing or something
2019-04-17

- Run 1:
- The biggest takeaway I have is that this workload benefits from a larger
filterCache
(for Solr fq parameter), but barely uses thequeryResultCache
(for Solr q parameter) at all- The number of hits goes up and the time taken decreases when we increase the
filterCache
, and total JVM heap memory doesn't seem to increase much at all - I guess the
queryResultCache
size is always 2 because I'm only doing two queries:type:0
andtype:2
(downloads and views, respectively)
- The number of hits goes up and the time taken decreases when we increase the
- Here is the general pattern of running three sequential indexing runs as seen in VisualVM while monitoring the Tomcat process:
- I ran one test with a
filterCache
of 16384 to try to see if I could make the Tomcat JVM memory balloon, but actually it drastically increased the performance and memory usage of the dspace-statistics-api indexer - 4GB heap, CMS GC, 16384 filter cache, 512 query cache, with 28 million documents in two shards

- The JVM garbage collection graph is MUCH flatter, and memory usage is much lower (not to mention a drop in GC-related CPU usage)!
- I will deploy this
filterCache
setting on DSpace Test (linode19) - Run all system updates on DSpace Test (linode19) and reboot it
- Lots of CPU steal going on still on CGSpace (linode18):
2019-04-18
- I've been trying to copy the
statistics-2018
Solr core from CGSpace to DSpace Test since yesterday, but the network speed is like 20KiB/sec- I opened a support ticket to ask Linode to investigate
- They asked me to send an
mtr
report from Fremont to Frankfurt and vice versa
- Deploy Tomcat 7.0.94 on DSpace Test (linode19)
- Also, I realized that the CMS GC changes I deployed a few days ago were ignored by Tomcat because of something with how Ansible formatted the options string
- I needed to use the "folded" YAML variable format
>-
(with the dash so it doesn't add a return at the end)
- UptimeRobot says that CGSpace went "down" this afternoon, but I looked at the CPU steal with
iostat 1 10
and it's in the 50s and 60s- The munin graph shows a lot of CPU steal (red) currently (and over all during the week):
- I opened a ticket with Linode to migrate us somewhere
- They agreed to migrate us to a quieter host
2019-04-20
- Linode agreed to move CGSpace (linode18) to a new machine shortly after I filed my ticket about CPU steal two days ago and now the load is much more sane:
- For future reference, Linode mentioned that they consider CPU steal above 8% to be significant
- Regarding the other Linode issue about speed, I did a test with
iperf
between linode18 and linode19:
# iperf -s

- Even with the software firewalls disabled the rsync speed was low, so it's not a rate limiting issue
- I also tried to download a file over HTTPS from CGSpace to DSpace Test, but it was capped at 20KiB/sec
- I updated the Linode issue with this information
- I'm going to try to switch the kernel to the latest upstream (5.0.8) instead of Linode's latest x86_64
- Nope, still 20KiB/sec
2019-04-21
- Deploy Solr 4.10.4 on CGSpace (linode18)
- Deploy Tomcat 7.0.94 on CGSpace
- Deploy dspace-statistics-api v1.0.0 on CGSpace
- Linode support replicated the results I had from the network speed testing and said they don't know why it's so slow
- They offered to live migrate the instance to another host to see if that helps
2019-04-22
- Abenet pointed out an item that doesn't have an Altmetric score on CGSpace, but has a score of 343 in the CGSpace Altmetric dashboard
- I tweeted the Handle to see if it will pick it up...
- Like clockwork, after fifteen minutes there was a donut showing on CGSpace
- I want to get rid of this annoying warning that is constantly in our DSpace logs:
2019-04-08 19:02:31,770 WARN org.dspace.xoai.services.impl.xoai.DSpaceRepositoryConfiguration @ { OAI 2.0 :: DSpace } Not able to retrieve the dspace.oai.url property from oai.cfg. Falling back to request address
- Apparently it happens once per request, which can be at least 1,500 times per day according to the DSpace logs on CGSpace (linode18):
$ grep -c 'Falling back to request address' dspace.log.2019-04-20
dspace.log.2019-04-20:1515
- I will fix it in
dspace/config/modules/oai.cfg
- Linode says that it is likely that the host CGSpace (linode18) is on is showing signs of hardware failure and they recommended that I migrate the VM to a new host
- I told them to migrate it at 04:00:00AM Frankfurt time, when nobody in East Africa, Europe, or South America should be using the server
2019-04-23
- One blog post says that there is no overprovisioning in Azure:
In Azure, with one exception being the A0, there is no overprovisioning… Each physical cores is only supporting one virtual core.
- Perhaps that's why the Azure pricing is so expensive!
- Add a privacy page to CGSpace
- The work was mostly similar to the About page at
/page/about
, but in addition to adding i18n strings etc, I had to add the logic for the trail todspace-xmlui-mirage2/src/main/webapp/xsl/preprocess/general.xsl
- The work was mostly similar to the About page at
2019-04-24
- Linode migrated CGSpace (linode18) to a new host, but I am still getting poor performance when copying data to DSpace Test (linode19)
- I asked them if we can migrate DSpace Test to a new host
- They migrated DSpace Test to a new host and the rsync speed from Frankfurt was still capped at 20KiB/sec...
- I booted DSpace Test to a rescue CD and tried the rsync from CGSpace there too, but it was still capped at 20KiB/sec...
- I copied the 18GB
statistics-2018
Solr core from Frankfurt to a Linode in London at 15MiB/sec, then from the London one to DSpace Test in Fremont at 15MiB/sec... so WTF us up with Frankfurt→Fremont?!
- Finally upload the 218 IITA items from March to CGSpace
- Abenet and I had to do a little bit more work to correct the metadata of one item that appeared to be a duplicate, but really just had the wrong DOI
- While I was uploading the IITA records I noticed that twenty of the records Sisay uploaded in 2018-09 had double Handles (
dc.identifier.uri
)- According to my notes in 2018-09 I had noticed this when he uploaded the records and told him to remove them, but he didn't...
- I exported the IITA community as a CSV then used
csvcut
to extract the two URI columns and identify and fix the records:
$ csvcut -c id,dc.identifier.uri,'dc.identifier.uri[]' ~/Downloads/2019-04-24-IITA.csv > /tmp/iita.csv
- Carlos Tejo from the Land Portal had been emailing me this week to ask about the old REST API that Tsega was building in 2017
- I told him we never finished it, and that he should try to use the
/items/find-by-metadata-field
endpoint, with the caveat that you need to match the language attribute exactly (ie "en", "en_US", null, etc) - I asked him how many terms they are interested in, as we could probably make it easier by normalizing the language attributes of these fields (it would help us anyways)
- He says he's getting HTTP 401 errors when trying to search for CPWF subject terms, which I can reproduce:
- I told him we never finished it, and that he should try to use the
$ curl -f -H "accept: application/json" -H "Content-Type: application/json" -X POST "https://dspacetest.cgiar.org/rest/items/find-by-metadata-field" -d '{"key":"cg.subject.cpwf", "value":"WATER MANAGEMENT","language": "en_US"}'
curl: (22) The requested URL returned error: 401
- Note that curl only shows the HTTP 401 error if you use
-f
(fail), and only then if you don't include-s
- I see there are about 1,000 items using CPWF subject "WATER MANAGEMENT" in the database, so there should definitely be results
- The breakdown of
text_lang
fields used in those items is 942:
dspace=# SELECT COUNT(text_value) FROM metadatavalue WHERE resource_type_id=2 AND metadata_field_id=208 AND text_value='WATER MANAGEMENT' AND text_lang='en_US';

- I see that the HTTP 401 issue seems to be a bug due to an item that the user doesn't have permission to access... from the DSpace log:
2019-04-24 08:11:51,129 INFO org.dspace.rest.ItemsResource @ Looking for item with metadata(key=cg.subject.cpwf,value=WATER MANAGEMENT, language=en_US).
2019-04-24 08:11:51,231 INFO org.dspace.usage.LoggerUsageEventListener @ anonymous::view_item:handle=10568/72448
2019-04-24 08:11:51,238 INFO org.dspace.usage.LoggerUsageEventListener @ anonymous::view_item:handle=10568/72491

2019-04-24 08:11:51,252 ERROR org.dspace.rest.ItemsResource @ User(anonymous) has not permission to read item!
- Nevertheless, if I request using the
null
language I get 1020 results, plus 179 for a blank language attribute:
$ curl -s -H "Content-Type: application/json" -X POST "https://dspacetest.cgiar.org/rest/items/find-by-metadata-field" -d '{"key":"cg.subject.cpwf", "value":"WATER MANAGEMENT","language": null}' | jq length
1020
$ curl -s -H "Content-Type: application/json" -X POST "https://dspacetest.cgiar.org/rest/items/find-by-metadata-field" -d '{"key":"cg.subject.cpwf", "value":"WATER MANAGEMENT","language": ""}' | jq length
179
- This is weird because I see 942–1156 items with "WATER MANAGEMENT" (depending on wildcard matching for errors in subject spelling):
dspace=# SELECT COUNT(text_value) FROM metadatavalue WHERE resource_type_id=2 AND metadata_field_id=208 AND text_value='WATER MANAGEMENT';
count
-------
942
(1 row)
dspace=# SELECT COUNT(text_value) FROM metadatavalue WHERE resource_type_id=2 AND metadata_field_id=208 AND text_value LIKE '%WATER MANAGEMENT%';
count
-------
1156

- I sent a message to the dspace-tech mailing list to ask for help
2019-04-25
- Peter pointed out that we need to remove Delicious and Google+ from our social sharing links
- Also, it would be nice if we could include the item title in the shared link
- I created an issue on GitHub to track this (#419)
- I tested the REST API after logging in with my super admin account and I was able to get results for the problematic query:
$ curl -f -H "Content-Type: application/json" -X POST "https://dspacetest.cgiar.org/rest/login" -d '{"email":"example@me.com","password":"fuuuuu"}'
$ curl -f -H "Content-Type: application/json" -H "rest-dspace-token: b43d41a6-5ac1-455d-b49a-616b8debc25b" -X GET "https://dspacetest.cgiar.org/rest/status"
$ curl -f -H "rest-dspace-token: b43d41a6-5ac1-455d-b49a-616b8debc25b" -H "Content-Type: application/json" -X POST "https://dspacetest.cgiar.org/rest/items/find-by-metadata-field" -d '{"key":"cg.subject.cpwf", "value":"WATER MANAGEMENT","language": "en_US"}'
- I created a normal user for Carlos to try as an unprivileged user:
$ dspace user --add --givenname Carlos --surname Tejo --email blah@blah.com --password 'ddmmdd'
- But still I get the HTTP 401 and I have no idea which item is causing it
- I enabled more verbose logging in
ItemsResource.java
and now I can at least see the item ID that causes the failure...- The item is not even in the archive, but somehow it is discoverable
dspace=# SELECT * FROM item WHERE item_id=74648;
item_id | submitter_id | in_archive | withdrawn | last_modified | owning_collection | discoverable
---------+--------------+------------+-----------+----------------------------+-------------------+--------------
74648 | 113 | f | f | 2016-03-30 09:00:52.131+00 | | t
(1 row)
- I tried to delete the item in the web interface, and it seems successful, but I can still access the item in the admin interface, and nothing changes in PostgreSQL
- Meet with CodeObia to see progress on AReS version 2
- Marissa Van Epp asked me to add a few new metadata values to their Phase II Project Tags field (cg.identifier.ccafsprojectpii)
- I created a pull request for it and will do it the next time I run updates on CGSpace
- Communicate with Carlos Tejo from the Land Portal about the
/items/find-by-metadata-value
endpoint - Run all system updates on DSpace Test (linode19) and reboot it
2019-04-26
- Export a list of authors for Peter to look through:
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/2019-04-26-all-authors.csv with csv header;
COPY 65752
2019-04-28
- Still trying to figure out the issue with the items that cause the REST API's
/items/find-by-metadata-value
endpoint to throw an exception- I made the item private in the UI and then I see in the UI and PostgreSQL that it is no longer discoverable:
dspace=# SELECT * FROM item WHERE item_id=74648;
item_id | submitter_id | in_archive | withdrawn | last_modified | owning_collection | discoverable
---------+--------------+------------+-----------+----------------------------+-------------------+--------------
74648 | 113 | f | f | 2019-04-28 08:48:52.114-07 | | f
(1 row)
- And I tried the
curl
command from above again, but I still get the HTTP 401 and and the same error in the DSpace log:
2019-04-28 08:53:07,170 ERROR org.dspace.rest.ItemsResource @ User(anonymous) has not permission to read item(id=74648)!
- I even tried to "expunge" the item using an action in CSV, and it said "EXPUNGED!" but the item is still there...
2019-04-30
- Send mail to the dspace-tech mailing list to ask about the item expunge issue
- Delete and re-create Podman container for dspacedb after pulling a new PostgreSQL container:
$ podman run --name dspacedb -v dspacedb_data:/var/lib/postgresql/data -e POSTGRES_PASSWORD=postgres -p 5432:5432 -d postgres:9.6-alpine
- Carlos from LandPortal asked if I could export CGSpace in a machine-readable format so I think I'll try to do a CSV
- In order to make it easier for him to understand the CSV I will normalize the text languages (minus the provenance field) on my local development instance before exporting:
dspace=# SELECT DISTINCT text_lang, count(*) FROM metadatavalue WHERE resource_type_id = 2 AND metadata_field_id != 28 GROUP BY text_lang;
text_lang | count
-----------+---------
| 358647
* | 11
E. | 1
en | 1635
en_US | 602312
es | 12
es_ES | 2
ethnob | 1
fr | 2
spa | 2
| 1074345
(11 rows)
dspace=# UPDATE metadatavalue SET text_lang='en_US' WHERE resource_type_id=2 AND metadata_field_id != 28 AND text_lang IN ('ethnob', 'en', '*', 'E.', '');
UPDATE 360295
dspace=# UPDATE metadatavalue SET text_lang='en_US' WHERE resource_type_id=2 AND metadata_field_id != 28 AND text_lang IS NULL;
UPDATE 1074345
dspace=# UPDATE metadatavalue SET text_lang='es_ES' WHERE resource_type_id=2 AND metadata_field_id != 28 AND text_lang IN ('es', 'spa');
UPDATE 14
- Then I exported the whole repository as CSV, imported it into OpenRefine, removed a few unneeded columns, exported it, zipped it down to 36MB, and emailed a link to Carlos
- In other news, while I was looking through the CSV in OpenRefine I saw lots of weird values in some fields... we should check, for example:
- issue dates
- items missing handles
- authorship types
