I wish the authors good luck with this but I don't think I would be able to use it for collecting metrics in my "enterprise applications" as we already have several messaging systems e.g. (i) TIBCO (ii) MQ Series (iii)ActiveMQ ; the infrastructure guys will throw a hissy fit if I try to sneak in yet another messaging system -- especially for only metrics collection.<p>In my current setup ( a java enterprise application) , we have a ActiveMQ adapter for log4j which pushes of all the Error and Warning messages to an MQ Series Queue asynchronously. There is a consumer which reads the messages off the queue and processes them and writes results to a SQL database. we have a simple webapp that allows people to download this data as CSV files , load it into Excel and do analysis.
