+1 the patch looks good.
I think the monitoring tools and scripts are quite useful, though it would have been great to have forrest docs for all the plugins like ganglia/others, so that we can publish them as part of the release documentation!! Please consider adding forrest documentation (it should not be hard at all)!!! It would be really good to have admin documentation link to these forrest docs in case they want to use it!
Having all the documentation as forrest docs and availalbe on the documentation website (as part of release) will highly increase the adoption of such a plugin!
