Path redirect usage statistics

If there are lots of nodes where pathauto rules have changed so that many 301 redirect aliases exist, the database may be full of paths that really aren't necessary. But, we don't know unless we can identify how often an alias has been requested. It would be good to have a report that shows all aliases per node and how often each alias has been requested in a given time period. A bonus would be to have a checkbox next to each for mass deletion and/or a way to delete all aliases that have not be requested from within a certain time period (for example within the last month). This would also be useful for path_redirect url redirects.
