I've installed all the necessary files and apps and it works out of the box.
Viewed it from OpenWrt Luci GUI where there is a link to "graphs". Whenever
I click on it, I assume it generates a new graph.
The link after I click on the graph is
http://some.domain.com/cgi-bin/luci/;stok=7f89f706f496f584539ee6487065c61b/admin/statistics/graph/interface/
?
How do I find the CGI?
