 - After forcing a complete re-indexing of OAI the mappings were fine
 - The `dateStamp` is most probably only updated when the item's metadata changes, not its mappings, so if Altmetric is relying on that we're in a tricky spot
 - We need to make sure that our OAI isn't publicizing stale data... I was going to post something on the dspace-tech mailing list, but never did
+- Linode says that CGSpace (linode18) has had high CPU for the past two hours
+- The top IP addresses today are:
+
+```
+# zcat --force /var/log/nginx/rest.log /var/log/nginx/rest.log.1 | grep -E "13/Sep/2018" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10

+   1840 50.116.102.77
+   4469 70.32.83.92
+```
+
+- And the top two addresses seem to be re-using their Tomcat sessions properly:
+
+```
+$ grep -c -E 'session_id=[A-Z0-9]{32}:ip_addr=70.32.83.92' dspace.log.2018-09-13 | sort | uniq
+7
+$ grep -c -E 'session_id=[A-Z0-9]{32}:ip_addr=50.116.102.77' dspace.log.2018-09-13 | sort | uniq
+2
+```
+
+- So I'm not sure what's going on
+- Valerio asked me if there's a way to get the page views and downloads from CGSpace
+- I said no, but that we might be able to piggyback on the Atmire statlet REST API
+- For example, when you expand the "statlet" at the bottom of an item like [10568/97103](https://cgspace.cgiar.org/handle/10568/97103) you can see the following request in the browser console:
+
+```
+https://cgspace.cgiar.org/rest/statlets?handle=10568/97103&_=1536844046540
+```
+
+- That JSON file has the total page views and item downloads for the item...
