      • Hit – The file was accessed from the cache: it was not a stub file.
      • Miss – The file was a stub file that was downloaded from the portal. However, the file had not been accessed within the last 24 hours.
      • Thrashing – The file was a stub file that was downloaded from the portal. The file was not in the cache for less than 24 hours. Thrashing means that files that were recently evicted are needed.
    • Hit Rate – The hit rate: A measurement of how many content requests a cache is able to fill successfully, hits, compared to how many requests it receives. The higher the cache hit ratio, the healthier the system.
