log4j

问题 I have a distributed system that all of them use lig4j for log system events.I have a Cassandra cluster that I want to put all of my logs in log4j format in that. Is there any open source program that integrates logs in log4j format to my Cassandra cluster? 回答1: A good choice would be Apache Flume. https://cwiki.apache.org/FLUME/ Flume is distributed log collection engine.

I figured out that the culprit was that I have two instances Tomcat running the same app which both had a hold of the same log file, so neither one could roll it over because of the other one. However, I would still like to use the same log file. I use two instances for load balancing and it would be annoying to have a log file for each instance. Is there any way I can do
