luci-app-statistics

Out of the box, OpenWRT can show you real-time statistics, however it will not store the data for historical view. Install luci-app-statistics to have a nice historical data graphs for router, eg: ping, interfaces bandwidth utilization, cpu load, ram, disk, uptime, etc…

To see all the available collectd-modules, run: opkg list | grep collectd-mod

I've found the original description located at: https://advanxer.com/blog/2013/02/openwrt-monitoring-using-collectd/ Thanks to advanxer.com!

luci-app-statistics is a collectd and rrdtool based statistics tool. For more details about collectd and rrdtool, see statistical.data.overview

For other Bandwidth Monitoring tools, see bwmon

The luci-app-statistics package is based on Collectd and uses RRD Tool to render diagram images from collected data.

1. opkg update and install

opkg update
opkg install luci-app-statistics

2. Install desired plugins

Several are suggested below, but many more exist. To see all the available collectd-modules, run: opkg list | grep collectd-mod

opkg list | grep collectd-mod
opkg install collectd-mod-ethstat collectd-mod-ipstatistics collectd-mod-irq collectd-mod-load collectd-mod-ping collectd-mod-powerdns collectd-mod-sqm collectd-mod-thermal collectd-mod-wireless

3. Enable daemons

/etc/init.d/collectd enable

Note that /tmp/rrd, the directory that keeps statistics data, resides in RAM and consequently will be lost after a reboot. To prevent this, you can configure a persistent storage location - see below.

Configuration via UCI:

  • View the config with uci export luci_statistics
  • Edit /etc/config/luci_statistics to make changes.

Configuration via LuCI: After installing the packages, a new menu appears. See the config pages in Statistics→Setup All the installed collectd-modules will shown here, but only some of them are enabled by default.

  • General Plugins tab: Review the sub-tabs to choose which statistics to monitor
  • Network Plugins tab: Select which interfaces to monitor
  • Output Plugins tab:
    • RRDtool sub-tab: To protect flash-memory from wearing out, the default Storage directory is /tmp/rrd. All statistics data will be lost on reboot. Alternatives:
    • Network sub-tab: collectd can either listen for other router's data, or send its data to other routers
