I've implemented this on Ohio State's instance. I've divided the bytes by (1024*1024*1024) to work around the too-big for int problem.
Our code is at: https://github.com/osulibraries/DSpace/blob/osukb/dspace-xmlui/dspace-xmlui-api/src/main/java/org/dspace/app/xmlui/aspect/dashboard/ContentStatistics.java
Example use in production: https://kb.osu.edu/dspace/content-statistics (Its slow loading).
<dspace-repository-statistics date="20131024T193427Z">
<statistic name="communities">189</statistic>
<statistic name="collections">1475</statistic>
<statistic name="items">54188</statistic>
<statistic name="bitstreams">118424</statistic>
<statistic name="totalMBytes">111867</statistic>
<statistic name="images">86495</statistic>
<statistic name="imageMBytes">8907</statistic>
</dspace-repository-statistics>
mhwood and I were discussing this in #dspace, and we determined that stuffing this in REST might not be a bad idea, and we found this advice: https://blog.apigee.com/detail/restful_api_design_what_about_counts
-- Say, you want a count of all of some resource (scoped based on whatever the requester has access to).
-- /dogs/count
-- In this way, you think about "count" as a reserved word.
Thus, this might fit into REST at endpoints: /communities/count, /collections/count, /items/count, /bitstreams/count, /bitstreams/size?unit=GB, /bitstreams/count?mimetype=image*, /bitstreams/size?unit=GB&mimetype=image*
The DB logic couldn't reside in rest though, it would have to move to dspace-api.

A tiny servlet to return counts of bitstreams, items, collections, and communities, and the amount of storage occupied. The attached patch also maps it into both JSPUI and XMLUI at /content-statistics.
The returned "page" is an XML document. For now, see the package.html changes in the patch. I'll update the end-user documentation presently.
