What YAMon users are saying:

Sign-up to get automatic notifications when there are updates to YAMon.

Yet Another Monitor (YAMon) records and reports on the traffic (downloads and uploads) for all of the devices connecting to your router. The data is aggregated by hour, day and month (within your ISP billing interval) and can be rolled-up into arbitrary groups (e.g., by family member or by any other logical grouping of devices).

In short, YAMon gives you an unprecedented view of the traffic on your router.

  • YAMon's Daily Usage and Hourly Usage reports allow you to see which devices used how much bandwidth, when? (Did your kids really really go to school? Did they really shut off their devices at bedtime?).
  • The Monthly Usage report shows who is consuming the most bandwidth on which device and projects your total usage for your ISP billing interval (allowing you to throttle consumption before you get hit with a large overage fee).
  • The Live Usage reports allow you to see which IP addresses each device is connecting to and includes geo-location lookups (you can find out, or at least, ask why your kid's device is connecting to a server in Lithunia or elsewhere)
  • The Devices tab allows you to organize the devices into logical groups (e.g., by family member or device owner, or by function/location)
  • Usage history reports allow you to view and compare results across billing intervals.
  • You can optionally include upload/download figures from your ISP to compare totals recorded at your router with theirs.
  • You can define an unlimited usage interval (as some ISPs do not count usage between 2AM and 7AM towards your bandwidth cap).
  • Optional database integration allows you to share your YAMon settings, etc. across all devices you use to access the reports.
  • etc.

All completely configurable to suit your specific needs.

Need a new router?

Coming in YAMon v4 (now in beta), a completely new modular architecture running in a series of cron jobs rather than a monolithic constantly-running process.

New in 3.0, YAMon includes optional support for IPv6 traffic.. the first tool of this kind to support this capability. Also, a simple install script that walks you through the setup & configuration process.

YAMon requires a router with at least one USB port that has been flashed with one of the *WRT firmware variants (e.g. DD-WRT, Turris, OpenWrt / LEDE, Asuswrt-Merlin, Tomato, etc.).
