- I see I can monitor the number of Tomcat threads and some detailed JVM memory stuff if I install `munin-plugins-java`
- I'd still like to get arbitrary mbeans like activeSessions etc, though
- I can't remember if I had to configure the jmx settings in `/etc/munin/plugin-conf.d/munin-node` or not—I think all I did was re-run the `munin-node-configure` script and of course enable JMX in Tomcat's JVM options
## 2018-01-23
- Thinking about generating a jmeter test plan for DSpace, along the lines of [Georgetown's dspace-performance-test](https://github.com/Georgetown-University-Libraries/dspace-performance-test)
- I got a list of all the GET requests on CGSpace for January 21st (the last time Linode complained the load was high), excluding admin calls:
```
# zcat --force /var/log/nginx/access.log.2.gz /var/log/nginx/access.log.3.gz /var/log/nginx/library-access.log.2.gz /var/log/nginx/library-access.log.3.gz /var/log/nginx/rest.log.2.gz /var/log/nginx/rest.log.3.gz /var/log/nginx/oai.log.2.gz /var/log/nginx/oai.log.3.gz /var/log/nginx/error.log.2.gz /var/log/nginx/error.log.3.gz | grep "21/Jan/2018" | grep "GET " | grep -c -v "/admin"
56405
```
- Apparently about 28% of these requests were for bitstreams, 30% for the REST API, and 30% for handles:
```
# zcat --force /var/log/nginx/access.log.2.gz /var/log/nginx/access.log.3.gz /var/log/nginx/library-access.log.2.gz /var/log/nginx/library-access.log.3.gz /var/log/nginx/rest.log.2.gz /var/log/nginx/rest.log.3.gz /var/log/nginx/oai.log.2.gz /var/log/nginx/oai.log.3.gz /var/log/nginx/error.log.2.gz /var/log/nginx/error.log.3.gz | grep "21/Jan/2018" | grep "GET " | grep -v "/admin" | awk '{print $7}' | grep -Eo "^/(handle|bitstream|rest|oai)/" | sort | uniq -c | sort -n
38 /oai/
14406 /bitstream/
15179 /rest/
15191 /handle/
```
- And 3% were to the homepage or search:
```
# zcat --force /var/log/nginx/access.log.2.gz /var/log/nginx/access.log.3.gz /var/log/nginx/library-access.log.2.gz /var/log/nginx/library-access.log.3.gz /var/log/nginx/rest.log.2.gz /var/log/nginx/rest.log.3.gz /var/log/nginx/oai.log.2.gz /var/log/nginx/oai.log.3.gz /var/log/nginx/error.log.2.gz /var/log/nginx/error.log.3.gz | grep "21/Jan/2018" | grep "GET " | grep -v "/admin" | awk '{print $7}' | grep -Eo '^/($|open-search|discover)' | sort | uniq -c
1050 /
413 /discover
170 /open-search
```
- The last 10% or so seem to be for static assets that would be served by nginx anyways:
```
# zcat --force /var/log/nginx/access.log.2.gz /var/log/nginx/access.log.3.gz /var/log/nginx/library-access.log.2.gz /var/log/nginx/library-access.log.3.gz /var/log/nginx/rest.log.2.gz /var/log/nginx/rest.log.3.gz /var/log/nginx/oai.log.2.gz /var/log/nginx/oai.log.3.gz /var/log/nginx/error.log.2.gz /var/log/nginx/error.log.3.gz | grep "21/Jan/2018" | grep "GET " | grep -v "/admin" | awk '{print $7}' | grep -v bitstream | grep -Eo '\.(js|css|png|jpg|jpeg|php|svg|gif|txt|map)$' | sort | uniq -c | sort -n
2 .gif
7 .css
84 .js
433 .php

```
- I can definitely design a test plan on this!
