[tor-relays] Light Bandwidth Monitor (like Munin)

Hey all,

May be RPi users... and others linux users! I'm looking for a light bandwidth graph software producing html files, to monitor and graph up/down eth0 bandwidth used on my RPi Tor relay.

Something like "munin" or "cacti", but I remember this one was very heavy on a RPi v1... It was taking tooo much time to collect/treat/graph :s

Which one are you using on your RPi's ?

Thx all for your answers !
