The JBoss.org Team is pleased to release JBoss.org Statistics, available at stats.jboss.org. We provide JIRA and Subversion statistics for projects hosted at JBoss.org.
JBoss.org Statistics are powered by Kosmos, created by Aron Gombas. They run on JBoss Portal.

Needless to say, you will find more at stats.jboss.org.
Enjoy,
