You can't track misses on a per-key basis because the statistics are stored on object IN the cache and if there was a miss, there would be no element in the cache to track it. But if you want a hit-count for all the keys in a cache you'd need to do something like:

public Map<Object,long> getKeyHits(Ehcache cache)  {    Map<Object,long> hitMap = new HashMap<Object,long>();    Map<Object,Element> allElements = cache.getAll(cache.getKeys());    for (Object key : allElements.keySet())    {      hitMap.put(key, allElements.get(key).hitCount());    }    return hitMap;  }
