Just in case there are any V130 users out there interested in stats I have been experimenting with a pi3 and munin. Firstly though I must thank and credit the scripts to a fellow member "smf22" after I contacted him and he helped me with his scripts.
Its nice to be able to see some stats from the v130 as most know it only has one lan port. I had to get opnsense to allow me to see the modem via the wan port but so far its working well. I have found the line to be more stable since swapping over to v130. I like it that you can tweak the SNR values, this has worked well and did increase my DS sync by a few mb, obviously I am not going to push it as stability is preferred over speed for me especially with my troublesome eci cab/line.
The pi3 seems to be coping, you can have a look at some stats
http://nedsv130athome.hopto.org or see an example below. Uptime now for munin nearly a week.
happy to share any info if someone else wants to have a go etc.
