    Description

      We should give users a way to track hits/misses in the page cache. This will help users tune the size of the page cache. JMX-visible monitors might be a useful solution here. See the following email thread: http://old.nabble.com/Cache-Hit-Miss-rates-for-Derby-pageCache-to33865646.html#a33865646
