Nginx extended_status

[EnriqueR]

I have configured on my server preinstalled extension stub_status. The problem of this extension is that this offers little information. I've looked online and there is an extension called "extended_status", with much more information and a much more attractive display.

I've been looking at how to install it and I find no reference.
Could you tell me how to install it on my Plesk server with CentOS 6 with Nginx 1.6.0?
