A look at the logging infrastructure that one division of Intuit built that included the requirement to handle 100K lines of logs per second with the logs being delivered to several destinations (including proprietary appliances).

This paper will cover the options considered, the choices made and the problems we ran into. The most unusual and interesting topic discussed is the method selected to distribute the logs to all the different destinations, able to deliver the log message to several different load balanced farms of servers with only one copy being sent over the wire.
