Subject Re: Zookeeper general log or “monitor” command

Hi Zod,

I think there's no such thing in ZooKeeper currently other than debug logs.
You might want to attach some processing engine to the debug log feed and
parse and output data which is important for you into MySQL or Redis

The downside of this approach is debug logging has significant performance
impact on the entire ensemble, but it might be acceptable for you analysis.
