      Given the planned dynamic eviction thresholds coming with precise checkpoint in DSC it would beneficial for the user if they could inspect the eviction thresholds in statistics data.

      Due to potential statistic name overloading the following names seem appropriate for the statistics:

      • eviction_threshold_cache_full_target
      • eviction_threshold_cache_full_trigger
      • eviction_threshold_cache_dirty_target
      • eviction_threshold_cache_dirty_trigger
      • eviction_threshold_cache_updates_target
      • eviction_threshold_cache_updates_trigger

      Scope:

      • Add thresholds
      • Observe them statistics data from a WiredTiger test run
