There's really is no such reporting for JIRA Capture sessions available as you have for JIRA issues currently. This issue is being tracked here: https://jira.atlassian.com/browse/BON-40.
The workaround that I guess a few people have adopted is to raise a specific JIRA issue (you may even have a special issue type for all such issues) and associate it with the session, just to track session details, and then you may be able to use available JIRA reporting tools/gadgets/plugins for statistical reports or time tracking of your sessions.
