I followed the instructions exactly to set up sensu on a RHEL 6 machine and installed from the yum repo. I believe this should have given me the omnibus package which takes care of all the dependencies.
I then tried setting up the check-procs.rb check per the example, but get the following in sensu-dashboard
/usr/bin/env: ruby: No such file or directory
Is it looking for dependency it can’t find?
