I'm not sure if you would consider the "beat" complete. But the source code is working for me.

Hi @2Fast2BCn

Thanks a lot for the addition and creation of a beat. Could you insert the beat alphabetically sorted into the list? Would you mind signing the CLA? http://www.elasticsearch.org/contributor-agreement/

Perhaps this beat could also be a nice addition of a metricset to the redis module in metricbeat: https://github.com/elastic/beats/tree/master/metricbeat/module/nginx What do you think?

[2Fast2BCn]

Yes, this all sounds good.
I changed the order.

LGTM. Let me know in case you need some help creating a MetricSet :-)
