statistics about segments

[Yoni Amir <Yo...@niceactimize.com>]

In the Solr UI, there is the number of segments in the core.
Is there information in Solr (in the UI or in xml responses) about their histogram? I.e., their size, how many are there in each size level? Are there any that are currently being merged, etc.?
Thanks,
Yoni
