logstash run from sysv init, upstart, etc, may not work

As there is a cookbook recipe for upstart, I suppose it is fixed in newer version.

http://cookbook.logstash.net/recipes/using-upstart/

Please reopen if it's not the case.

If you're having the issue with "no such file to load" - add:

export GEM_HOME=/var/lib/gems/1.8

or whatever your gem path (gem env) is to your init script.

This solved my issue.

I see the same issue as Simon. When I run the .jar from the command line, everything works just fine.
When I run an init script the agent will complain about missing gems.

Here's the command line I use that works PERFECTLY:
java -jar logstash-monolithic.jar agent -f /etc/logstash/devglog01.conf

Here's the init script: http://pastebin.com/9yfqmH6E

And finally here's the error in the logs after running the init script:
LoadError: no such file to load – file:/u01/logstash/logstash-monolithic.jar!/gems/bunny-0.7.8/lib/bunny/version

The problem exists also in the agent if you specify "amqp" in the "input" or "output".

I have been experimenting with logstash and the web service piece is the only part effected. The 'cd /tmp' work around does work. The issue is due to the environment not getting properly set. I don't know how to fix this, but it would be nice if some documentation existed for this work around, I have spent many hours trying to find out what the root cause is. I have found many places on the internet with this error, I think a fix would be greatly appreciated.
