2 questions

 1.  What are people using for logging servers for their web tier logging?
 2.  Would anyone be interested in a new logging server(any programming 
language) for web tier to log to your existing cassandra(it uses up disk space 
in proportion to number of web servers and just has a rolling window of logs 
along with a window of threshold dumps)?

Context for second question: I like less systems since it is less 
maintenance/operations cost and so yesterday I quickly wrote up some log back 
appenders which support (SLF4J/log4j/jdk/commons libraries) and send the logs 
from our client tier into cassandra.  It is simply a rolling window of logs so 
the space used in cassandra is proportional to the amount of web  servers I 
have(currently, I have 4 web servers).  I am also thinking about adding warning 
type logging such that on warning, the last N logs info and above are flushed 
along with the warning so basically two rolling windows.  Then in the GUI, it 
simply shows the logs and if you click on a session, it switches to a view with 
all the logs for that session(no matter which server since in our cluster the 
session switches servers on every request since we are stateless….our session 
id is in the cookie).

Well, let me know if anyone is interested and would actually use such a thing 
and if so, we might create a server around it.

Thanks,
Dean
