I've set up Munin and so far, loving it. I got some basic Nginx monitoring set up and am able to monitor Nginx's status and RAM usage (with stub_status compiled into Nginx and activated in the config). However, while in my adventures of getting Munin and Nginx set up to do this, I found the nginx_traffic Munin plugin. I've enabled it in Munin like I did for nginx_status and nginx_request, but my graphs for vhost traffic are still blank.
munin-node-configure --suggest shows nginx_request and nginx_status as activated and recommended, but doesn't show any other nginx_* plugins (though I have nginx_memory, and it's successfully graphing).
Can someone at least point me in the right direction for getting this plugin set up? I'd love to be able to use it.
