 - Spent a few hours with Moayad troubleshooting and improving OpenRXV
   - We found a bug in the harvesting code that can occur when you are harvesting DSpace 5 and DSpace 6 instances, as DSpace 5 uses numeric (long) IDs, and DSpace 6 uses UUIDs
 
+## 2021-06-25
+
+- The new OpenRXV code creates almost 200,000 jobs when the plugins start
+  - I figured out how to use [bee-queue/arena](https://github.com/bee-queue/arena/tree/master/example) to view our Bull job queue
+  - Also, we can see the jobs directly using redis-cli:
+
+```console
+$ redis-cli
+127.0.0.1:6379> SCAN 0 COUNT 5
+1) "49152"
+2) 1) "bull:plugins:476595"
+   2) "bull:plugins:367382"
+   3) "bull:plugins:369228"
+   4) "bull:plugins:438986"
+   5) "bull:plugins:366215"
+```
+
+- We can apparently get the names of the jobs in each hash using `hget`:
+
+```console
+127.0.0.1:6379> TYPE bull:plugins:401827
+hash
+127.0.0.1:6379> HGET bull:plugins:401827 name
+"dspace_add_missing_items"
+```
+
+- I whipped up a one liner to get the keys for all plugin jobs, convert to redis `HGET` commands to extract the value of the name field, and then sort them by their counts:
+
+```console
+$ redis-cli KEYS "bull:plugins:*" \
+  | sed -e 's/^bull/HGET bull/' -e 's/\([[:digit:]]\)$/\1 name/' \
+  | ncat -w 3 localhost 6379 \
+  | grep -v -E '^\$' | sort | uniq -c | sort -h
+      3 dspace_health_check
+      4 -ERR wrong number of arguments for 'hget' command
+     12 mel_downloads_and_views
+    129 dspace_altmetrics
+    932 dspace_downloads_and_views
+ 186428 dspace_add_missing_items
+```
+
+- Note that this uses `ncat` to send commands directly to redis all at once instead of one at a time (`netcat` didn't work here, as it doesn't know when our input is finished and never quits)
+  - I thought of using `redis-cli --pipe` but then you have to construct the commands in the redis protocol format with the number of args and length of each command
+- There is clearly something wrong with the new DSpace health check plugin, as it creates WAY too many jobs every time we run the plugins
