Question: question comes from reading a lot of articles, especially the ones describing pros and cons.

But each one of them is saying that even though connection itself is secured, data transfers are not. How's that even possible? I mean in both cases you set a essentially a tunnel between your host and remote location, obviously (aside from constant change of ips) that last outgoing connection might not be connected by tunnel itself but still last sign of incoming data should stop on that server -> when data is going back to you it should be already "covered" with vpn/tor tunnel right? And since some companies have based on rules in their country they don't keep logs all should be fine. So why then people are still saying that it's not secured?

Answer: 
Ping would be enough if it is really just about outages. You can use gping which provides a graphical result of the measures.
A ping won't affect the traffic.

As for alternatives, the question you linked in the first place has already some very good ones like mtr or MRTG.
Let's take a look at your ip address.
Open cmd.exe: Windows-button+R, type cmd, ENTER.
On prompt type: ipconfig

The ip address should be the same as ipconfig from cmd.exe above. Put these values in as "static values". Note the "preferred DNS".
