Max,
Do you have the webserver for dslstats on your LAN setup? (Or are you just looking at the pi desktop via a vncclient?).
If just by vnc, then I'd recommend *first* setting up the webserver to view via your LAN, which isn't hard. Kitz has kindly supplied some
php blah-blah in a thread that I'm sure you can find, that presents the main on-going stats in a pretty form. I look at mine
with my browser with an address like, eg, "
http://192.168.1.99:55555/connection.htm". Setting up the webserver is documented where you got
dslstats. The dslstats tab you need is "configuration>>webserver". Apologies if you know all that.
If you are happy with what that gives you, then consider opening a WAN port on your router forwarded to the pi. I'm not sure of the security implications of doing that, so haven't done it. But then you could look at the last day or two's stuff on holiday.
Mydslwebstats (is that the right name?) was an amazing service, frankly well worth 34 quid or whatever for 3 years, giving historical, graphical access to your stats. Anyway, it's gone. There are threads on this site discussing what might be done to store historical stats on an ftp server, dropbox or suchlike, if not to present the data as beautifully and meaningfully as mydslwebstats. I doubt there are many here with the combination of time, energy, knowledge and health to suggest how that might be accomplished, though it has obviously been desired, and others have thought a bit about it.
Anyway, to me, it seems with the demise of mdsl-thingy, I think there's a lesson about contributing some proper cash any such thing, and indeed to this very site, because (a) it's worth it, and (b) when it's gone its gone. I don't insinuate in any way you haven't, and apologise in advance if I've said anything patronising, which is far from my intention.,
