Add a device under the local probe of www.google.com.au then add a ping
sensor under that.

Well, it installed 1.4 Gigawatts of 7000+ files and started two Windows
services. It was well into a astonishingly deep probe of everything on the
LAN but I stopped it and deleted everything (except 3 sensors that seem
glued-in).

I created a Ping sensor, but it never asked me what to ping, so it's
sitting there doing who knows what! Removed it.

I added a HTTP sensor instead for https://whaitsmyipaddress.com/ but it
gives 403 all the time.

I replaced that with whatsmyip.org and it seems to be going now. I wonder
if they mind me issuing a GET call every minute from the same place? Is
there some special Url just for this sort of heartbeat checking?

1. Install on a PC/server that is always on.
2. Go to the local probe
3. Add ping sensors for stuff on the internet (google, etc)
4. Look at graphs

There is a lot more depth to the product but you'll get going pretty
quickly.

That's a nice looking product, but is it using a Synchrotron to heat my
cup-o-soup? How long will it take to learn to configure it just monitor if
my NBN connection is off or on? --* GK*

Is it something like ping google.com >> log.txt ? You need time stamps in
the output. I'd have to check at least every minute to get the required
granularity. I hope one day I have a miraculous cure like you did --* GK*

I wrote a two line batch script, piped the output to file, and charted in 
Excel. Then I had a conversation with my ISP about the results. Then Mr NBN 
came and fixed it (technican was very good, turns out original installer reused 
rather than replaced some BNCs or somesuch). Now all good.

(It happened to run on my Pi, but that's just because everything else I own is 
a laptop and doesn't stay on)

Nice work. I don't have a Pi, but I see them popping more and more recently in 
magazines and web articles. I have so many projects on the go that I doubt if 
I'll have time to experiment with that sort of thing before I retire from IT

If you have a Raspberry Pi hanging around, I use mine to monitor my
internet connection using smokeping based on this article:
https://votecharlie.com/blog/2016/04/network-monitoring-with-raspberry-pi-and-smokeping.html.
I decided on the PI as it means I don't need to have a PC turned on all the
time. (As an aside, the Pi also downloads my solar PV data ever 5 minutes
and uploads it to PV output).

You end up with graphs showing latency, and dropouts:

Network monitoring

[Greg Keogh]

Folks, my 2 year old NBN connection takes 5 minute breaks multiple times a
day, every day. The Internet connection randomly dies, the lights on the
Arris black box go out and slowly come back, then it's going again. Several
months ago I called Telstra who ran "tests" and declared it would be fixed.

I wrote a tiny command line program that uses the NetworkChange
NetworkAvailabilityChanged event to log changes, but it doesn't work, no
events are ever raised even though I can see the modem lights
flashing. The class
documentation

hints it does what I want, but there must be other adapters like the VMWare
ones that are ruining my expectations.

Is there some other way of easily monitoring up/down of the NBN connection?
Event log? Some utility program? Something I can write? Something in the
modem or switch? Anything?
