      This ticket adds a new stat that reports how many times eviction workers attempted to a evict a page before they were successful.

      This will likely require a new field on the WT_PAGE, or some tracking logic in the evict module. We don't need to know which page required X eviction attempts, just the maximum value for any page evicted during a certain time period. Similar to WT-14273 we can use "maximum page size seen at eviction" as an existing example for how the stat should be tracked.

      This stat should be increment each time eviction is attempted, and reported then cleared each time eviction is successful
