> At this time, we assessed whether zookeeper supports some business scenarios, always
use the number of subscribers, or to assess the number of clients。
> You konw, some times, many client connection with zookeeper, but do noting, and the onthers
do complex business logic。
> So,we must stat the realtime tps of zookeepr。
> [-----------------Solution-------------------]
> Solution1: 
> If you only want to know the real time transaction processed, you can use the patch "ZOOKEEPER-1804.patch".
> Solution2:
> If you also want to know how client use zookeeper, and the real time r/w ps of each zookeeper
client, you can use the patch "ZOOKEEPER-1804-2.patch"
