Installation Web interface instructions Install the packagee luci-app-statistics. Configure collectd using the tools in Statistics → Setup section of the LuCI web interface. By default, collectd saves its RRD data in /tmp/rrd which is a RAM-based directory, so its contents will be lost when the device reboots. To save the data across power failure/restarts, consider adding an external USB Drive and then configuring collectd to save the data to that new storage. Do this using the Output plugins → RRDTool tab in LuCI, configure the Storage directory, or the DataDir command of the <Plugin rrdtool> section of the collectd configuration file at /etc/collectd.conf. Command-line instructions opkg update opkg install collectd vi /etc/collectd.conf /etc/init.d/collectd restart Examples Minimal # /etc/collectd.conf BaseDir "/var/lib/collectd" PIDFile "/var/run/collectd.pid" Interval 30 ReadThreads 2 Simple opkg update opkg install collectd-mod-rrdtool collectd-mod-processes collectd-mod-interface # /etc/collectd.conf BaseDir "/var/run/collectd" Include "/etc/collectd/conf.d" PIDFile "/var/run/collectd.pid" PluginDir "/usr/lib/collectd" TypesDB "/usr/share/collectd/types.db" Interval 30 ReadThreads 2 LoadPlugin cpu LoadPlugin interface LoadPlugin load LoadPlugin memory LoadPlugin processes LoadPlugin rrdtool LoadPlugin uptime <Plugin interface> IgnoreSelected false Interface eth0 Interface eth1 Interface eth2 </Plugin> <Plugin processes> Process uhttpd Process dnsmasq Process dropbear </Plugin> <Plugin rrdtool> DataDir "/tmp/rrd" RRARows 100 RRASingle true RRATimespan 3600 RRATimespan 86400 RRATimespan 604800 RRATimespan 2678400 RRATimespan 31622400 </Plugin> Advanced opkg update opkg install collectd-mod-rrdtool collectd-mod-iptables collectd-mod-netlink # /etc/collectd.conf BaseDir "/var/lib/collectd" PIDFile "/var/run/collectd.pid" Interval 30 ReadThreads 2 LoadPlugin iptables LoadPlugin netlink LoadPlugin rrdtool # Use only iptables filter <Plugin iptables> chain mangle TC_USER1 chain mangle TC_USER2 chain mangle TC_USER3 </Plugin> <Plugin netlink> VerboseInterface pppoe-dsl QDisc "pppoe-dsl" "hfsc-1:0" Class "pppoe-dsl" "hfsc-1:1" Class "pppoe-dsl" "hfsc-1:10" Class "pppoe-dsl" "hfsc-1:101" Class "pppoe-dsl" "hfsc-1:102" Class "pppoe-dsl" "hfsc-1:103" Class "pppoe-dsl" "hfsc-1:20" Class "pppoe-dsl" "hfsc-1:201" Class "pppoe-dsl" "hfsc-1:202" Class "pppoe-dsl" "hfsc-1:203" Class "pppoe-dsl" "hfsc-1:30" Class "pppoe-dsl" "hfsc-1:301" Class "pppoe-dsl" "hfsc-1:302" Class "pppoe-dsl" "hfsc-1:303" Class "pppoe-dsl" "hfsc-1:40" Class "pppoe-dsl" "hfsc-1:50" </Plugin> <Plugin rrdtool> DataDir "/mnt/storage/rrd" CacheTimeout 120 CacheFlush 900 </Plugin> Ping check A simple ping check by IP address. opkg update opkg install luci-app-statistics collectd-mod-ping uci set luci_statistics.collectd_network.enable="1" uci set luci_statistics.collectd_ping.enable="1" uci set luci_statistics.collectd_ping.Hosts="8.8.8.8 8.8.4.4" uci commit luci_statistics /etc/init.d/luci_statistics restart /etc/init.d/collectd restart /etc/init.d/rpcd restart Ping check by domain name. Note that collectd always prefers IPv6 if not specified otherwise. uci set luci_statistics.collectd_ping.Hosts="openwrt.org" uci set luci_statistics.collectd_ping.AddressFamily="ipv4" uci commit luci_statistics /etc/init.d/luci_statistics restart Navigate to LuCI → Statistics → Graphs → Ping to see visualization results. Graphs and visualization collectd is strictly a statistics collection service and does not provide any way to visualize the gathered data. To enable visualization of the gathered data, install and configure the packages luci-app-statistics and collectd-mod-rrdtool. The statistics gathered by collectd should then be viewable in the LuCI web interface.
