Andrea Schweer commented on DS-552:
-----------------------------------
Mark, thanks for making this available on github.
I cherry-picked your commit (and changed it slightly to make it work on DSpace
1.8.2). When I run this (DSpace 1.8.2, PostgreSQL 8.4), I get an internal
server error with a "Bad value for type int" message. It looks to me like
PostgreSQL is trying to squish the sum of bytes into an int but it doesn't fit
(ca 46 GB, so totalBytes is 49582086693). I changed it locally to use
ceil(sum(size_bytes)/1024) rather than sum(size_bytes) to get an approximation
of KB instead, which circumvents the problem for me. An alternative might be to
explicitly cast the sum to bigint (sum(size_bytes)::bigint), which works on my
machine too. But I don't know what Oracle would make of that.

> Key: DS-552
> URL: https://jira.duraspace.org/browse/DS-552
> Project: DSpace
> Issue Type: New Feature
> Components: DSpace API
> Reporter: Mark H. Wood
> Assignee: Mark H. Wood
> Attachments: stats.patch
>
>
> 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.
> We use an earlier version of this with 1.5.1 as input to our library
> "dashboard", which gathers statistics on various services for quick reference.
