My memory is hazy here, but I think you might be using an old version of 
the plugin.  The most recent version can be found at

	git://ceph.newdream.net/git/collectd-4.1.10.git

in the 'ceph' branch.  Note that this isn't an upstream collectd tree... 
it's based on a debian package source snapshot, and the ceph-full-history 
branch has a bunch of build-related crap in git that shouldn't be.  

We aren't using it anymore, but the code works.  If you or someone else 
wants to adopt it and get it upstream into collectd that would be great!  

FWIW, dh has moved to statsd instead: https://github.com/etsy/statsd
