--- title: "February, 2019" date: 2019-02-01T21:37:30+02:00 author: "Alan Orth" tags: ["Notes"] --- ## 2019-02-01 - Linode has alerted a few times since last night that the CPU usage on CGSpace (linode18) was high despite me increasing the alert threshold last week from 250% to 275%—I might need to increase it again! - The top IPs before, during, and after this latest alert tonight were: ``` # zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "01/Feb/2019:(17|18|19|20|21)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10 245 207.46.13.5 332 54.70.40.11 385 5.143.231.38 405 207.46.13.173 405 207.46.13.75 1117 66.249.66.219 1121 35.237.175.180 1546 5.9.6.51 2474 45.5.186.2 5490 85.25.237.71 ``` - `85.25.237.71` is the "Linguee Bot" that I first saw last month - The Solr statistics the past few months have been very high and I was wondering if the web server logs also showed an increase - There were just over 3 million accesses in the nginx logs last month: ``` # time zcat --force /var/log/nginx/* | grep -cE "[0-9]{1,2}/Jan/2019" 3018243 real 0m19.873s user 0m22.203s sys 0m1.979s ``` - Normally I'd say this was very high, but [about this time last year]({{< relref "2018-02.md" >}}) I remember thinking the same thing when we had 3.1 million... - I will have to keep an eye on this to see if there is some error in Solr... - Atmire sent their [pull request to re-enable the Metadata Quality Module (MQM) on our `5_x-dev` branch](https://github.com/ilri/DSpace/pull/407) today - I will test it next week and send them feedback ## 2019-02-02 - Another alert from Linode about CGSpace (linode18) this morning, here are the top IPs in the web server logs before, during, and after that time: ``` # zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "02/Feb/2019:0(1|2|3|4|5)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10 284 18.195.78.144 329 207.46.13.32 417 35.237.175.180 448 34.218.226.147 694 2a01:4f8:13b:1296::2 718 2a01:4f8:140:3192::2 786 137.108.70.14 1002 5.9.6.51 6077 85.25.237.71 8726 45.5.184.2 ``` - `45.5.184.2` is CIAT and `85.25.237.71` is the new Linguee bot that I first noticed a few days ago - I will increase the Linode alert threshold from 275 to 300% because this is becoming too much! - I tested the Atmire Metadata Quality Module (MQM)'s duplicate checked on the some [WLE items](https://dspacetest.cgiar.org/handle/10568/81268) that I helped Udana with a few months ago on DSpace Test (linode19) and indeed it found many duplicates!
