Should it also update the GEM_HOME and GEM_PATH to /opt/sensu as well?

EMBEDDED_RUBY only affects processes that are spawned under the init
scripts. Sudo is unaware of it.

Here is what it affects:

github.com

sensu/sensu-build/blob/master/sensu_configs/init.d/sensu-service#L165-L172


      
          set_sensu_paths() {
              if [ "x$EMBEDDED_RUBY" = "xtrue" ]; then
                  export PATH=/opt/sensu/embedded/bin:$PATH:$PLUGINS_DIR:$HANDLERS_DIR
                  export GEM_PATH=/opt/sensu/embedded/lib/ruby/gems/2.3.0:$GEM_PATH
              else
                  export PATH=$PATH:$PLUGINS_DIR:$HANDLERS_DIR
              fi
          }

cat /proc/2134/environ to see if the current sensu proc has those vars.

Seems no matter what I do, it still uses the wrong ruby

^ Its working.
EMBEDDED_RUBY effects the *process*, not the *user*. It only takes
effect on something that is invoked with the init scripts

This won't make a difference. The EMBEDDED_RUBY setting only affects
processes spawned via the sensu init scripts.

root@ip-10-0-0-36:/proc/4259# sudo -u sensu /opt/sensu/embedded/bin/gem
install sensu-plugin

root@ip-10-0-0-36:/proc/4259# sudo -u sensu /opt/sensu/embedded/bin/gem
install sensu-plugin
Successfully installed sensu-plugin-1.2.0
Parsing documentation for sensu-plugin-1.2.0
Installing ri documentation for sensu-plugin-1.2.0
1 gem installed

This installed (upgraded?) the sensu-plugin gem in the embedded ruby.
(because you used the full path)

root@ip-10-0-0-36:/proc/4259# sudo -u sensu gem which sensu-plugin
/var/lib/gems/1.9.1/gems/sensu-plugin-1.1.0/lib/sensu-plugin.rb

This is looking in the system ruby. You have the sensu-plugin (1.1.0)
installed in your system ruby.

root@ip-10-0-0-36:/proc/4259# sudo -u sensu gem list

*** LOCAL GEMS ***

mixlib-cli (1.5.0)
sensu-plugin (1.1.0)
root@ip-10-0-0-36:/proc/4259# sudo -u sensu gem which sensu-plugin
/var/lib/gems/1.9.1/gems/sensu-plugin-1.1.0/lib/sensu-plugin.rb

These are system-installed gems. The fact that you used the sensu user
to list them is a red-herring.

Remember, you don't *have* to use EMBEDDED_RUBY, just use the full
path to the embedded ruby interpreter if it makes it easier (that's
how I do it)
I like that personally as it is more explicit what that I'm using a
different ruby to do the job.

Here is what it affects:
https://github.com/sensu/sensu-build/blob/master/sensu_configs/init.d/sensu-service#L165-L172

cat /proc/2134/environ to see if the current sensu proc has those vars.

Should it also update the GEM_HOME and GEM_PATH to /opt/sensu as well?
