A gauge metric is an instantaneous reading of a particular value. To instrument a queue's depth, for example:

 final Queue<String> queue = new ConcurrentLinkedQueue<String>();
 final Gauge<Integer> queueDepth = new Gauge<Integer>() {
     public Integer getValue() {
         return queue.size();
     }
 };
