Solitication for logging/debugging requirements

[Ivan Kelly]

Hi,

Im going to be using Zookeeper quite extensively for a project in a  
few weeks, but development hasn't kicked off yet. This means I have  
some time on my hands and I'd like to get familiar with zookeeper  
beforehand by perhaps writing some tools to make debugging problems  
with it easier so as to save myself some time in the future. Problem  
is I haven't had to debug many zookeeper problems yet, so I don't know  
where the pain points are.

So, without further ado,
	- Are there any places that logging is deficient that sorely needs  
improvement?
	- Could current logs be improved any amount or presented in a more  
readable fashion?
	- Would some form of log visualisation be useful (for example in  
something approximating a sequence diagram)?

Feel free to suggest anything which the list above doesn't allude to  
which you think would be helpful.

Cheers,
Ivan
