Where are Tomcat application log files stored in Elastic Beanstalk?

Question

Where does Elastic Beanstalk store log output from Tomcat on each EC2 instance?

I've configured SSH and want to tail the log file, but don't know where it's located.

Answer 1

Something seems to have changed a bit on this, as I have a new Elastic Beanstalk application where the logs are located in:

/var/log/tomcat7/

Note that the easiest way to view stuff in here is to sudo su first, as this directory is owned by root. Whereas, I have an older instance where the logs are in:

/opt/tomcat7/logs/

I'm not sure why there is a disparity in this, as both applications use the tomcat7 container, but this seems to be the state of things to date.

Answer 2

By default, AWS Elastic Beanstalk log output from Tomcat is written to /opt/tomcat7/logs/tail_catalina.out. (depends on Tomcat version)

These log messages are written by java.util.logging configured in Tomcat from /opt/tomcat7/conf.

edit: this was changed in late 2012 and now applies only to "Legacy" containers.
