[graylog2] No 'Beats Input' available to receive sidecar data.

[Chris Thompson]

I installed the plugin to my Graylog 2.2 appliance (I'm still testing) and
restarted the services.
I keep getting pointed to this
doc: http://docs.graylog.org/en/2.1/pages/collector_sidecar.html#step-by-step-guide
However, the first step in that doc is to make a 'Global Beats Input'.
'Beats' is not an option in my inputs drop down menu:

I tried installing the beats plugin (some were saying it ships with Graylog
but, it is not in the /opt/graylog/plugin folder on my OVA in any case.
Once I install it, when I restart graylog, it fails with this error showing
in a loop in /var/log/graylog/server/current:
