Ok, perfect!Thanks for info...As described in the intro, the original intent was to replace the built-in stats because on my RT-AC66U_B1 the stats were unreliable (ghost spikes). A fix pushed by Asus has supposedly fixed this for the HND routers, but some still report the spikes on non-HND models. If you have a HND model, vnStat-on-Merlin probably only adds the 'dashboard' view where you can see all usage without having to select different views.
I do not have a method to disable the built-in stats, but if you do, please share.
My pre-release performance testing with vnStat-on-Merlin demonstrates no material impact on CPU or router performance when run every 5 minutes. This application has been tested on single-core models (N66U) through quad-core (AX86U).
The testing, for example, included the single-core N66U running repeated vnStat-on-Merlin refreshes during video calls and during VOIP calls, with no artifacting noted.
About traffic analyzer, there is a toggle in the Asus settings to disable, or I'm wrong?
