[jira] [Created] (IGNITE-13726) Add an ability to view count of hot and cold pages in page memory

             Summary: Add an ability to view count of hot and cold pages in page memory
                 Key: IGNITE-13726
                 URL: https://issues.apache.org/jira/browse/IGNITE-13726
             Project: Ignite
          Issue Type: New Feature
            Reporter: Aleksey Plekhanov
            Assignee: Aleksey Plekhanov


Currently, we can't determine how many hot (touched recently) and cold pages we have in the page-memory. This information can be helpful for data region size tuning and can show the effectiveness of the page replacement algorithm.
Such information can be represented as a histogram showing the count of pages last touched in each time interval.
