The Statistics/Diagram page is still empty.
I installed:
collectd-mod-cpu
collectd-mod-interface
collectd-mod-iwinfo
collectd-mod-load
collectd-mod-memory
collectd-mod-network
collectd-mod-rrdtool
rrdtool1
lighttpd-mod-rrdtool
collectd-mod-rrdtool
I also set collectd as autostart and started it.
How do I set up the diagrams in Luci Statistic/Setup
I assume you’ve gone in to the Setup for the graphs, since some (most?) wont be enabled by default. One more thing to consider is there are two startup scripts related to this:
/etc/init.d/collectd
/etc/init.d/luci_statistics
I believe luci_statistics takes your luci config files and creates the collectd config file, then should run collectd. But collectd error reporting is spotty at best. Make sure collectd is running and if it isn’t running, you can run it by hand with some debug flags.
For beginners:
Simply visit the Luci web interface, find System, Startup and there press Enable and Start buttons on row collectd and luci_statistics.
That step enabled a new menu on statistics, graph - there will be all named modules (collectd-mod-…) and its graphs as you install it in the system, opkg software and configure it under statistics, collectd setting. Enjoy
