Your upstart job does:

  exec sudo -u root 'bundle exec /path_to_plugin/newrelic/newrelic_rs_dfw/bin/newrelic_rs' 

The obvious issue here is that this is the wrong syntax.  Quoting the string
'bundle exec [...]' causes sudo to try to find a program named 'bundle exec
[...]', instead of executing the program 'bundle' with arguments 'exec',
[...].

Note that it's recommended to not use sudo for upstart jobs, in general, as
sudo spawns an associated PAM session which is normally not what you want.
And if all you care about is the user id, then 'sudo -u root' is redundant
since all system jobs run as root by default.

Finally, if you have any further problems with this job, try looking in
/var/log/upstart/newrelic.log.  Assuming you're running a new enough
upstart, you will have logs there (including the error output of your failed
sudo commands).

Hope that helps,
