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?
