java - Store log output of many JBoss instances in a single location -

i have several machines on amazon each running jboss 4.2.3. although jboss instances serve single web application unaware of each other because behind elb (elastic load balancer). each instance has own server.log file. possible store log output of instances in single location? can done through jboss-log4j.xml of jboss? appreciate recommendations on how such solution can implemented.

regards

you use syslogappender in log4j send output of instances central syslog daemon on 1 of ec2 instances.
