OpenWrt includes real-time statistics however this does not store historical data for view by default. The luci-app-statistics package, based on collectd and rrdtool, will display historical graphs including ping, interface bandwidth utilization, cpu load, ram, disk, uptime, etc.
For more info see statistical.data.overview and collectd blog post.
For other Bandwidth Monitoring tools, see bwmon page.
1. Install package luci-app-statistics
. If using SSH run: 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 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 or configure backups - see below.
uci export luci_statistics
/etc/config/luci_statistics
to make changesAfter installing the packages, a new menu appears in Statistics → Setup. All the installed collectd-modules will show here, but only some are enabled by default.
/tmp/rrd
. All statistics data will be lost on reboot. Alternatives:uci set luci_statistics.collectd_rrdtool.backup=1
. The statistics are saved to flash-memory only at shutdown or sysupgrade time or when generating a backup archive. If your router crashes or suffers a power failure or other disorderly restart, the statistics history from the previous orderly shutdown will be restored during reboot. To create backups more frequently than shutdown/reboot/sysupgrade, create a cron job to run service luci_statistics backup
. (Full details of the mechanism are explained at https://github.com/openwrt/luci/tree/master/applications/luci-app-statistics#backups).
