             Summary: Expose metrics and gauges for fetcher cache usage and hit rate
                 Key: MESOS-4760
                 URL: https://issues.apache.org/jira/browse/MESOS-4760
             Project: Mesos
          Issue Type: Improvement
          Components: fetcher, statistics
            Reporter: Michael Browning
            Priority: Minor


To evaluate the fetcher cache and calibrate the value of the fetcher_cache_size flag, it would be useful to have metrics and gauges on agents that expose operational statistics like cache hit rate, occupied cache size, and time spent downloading resources that were not present.
