This is a little program I wrote just for my own use, but I'll share it because why not. It pings Google every 5 seconds and reports the time back and shows a graph of the ping. It's still a very buggy and beta-y program. Python file is attached to this post.

Features and stuff:

• Color-coded graph (1 hour wide, 8 seconds tall when pinging; 1 day wide when reading logs)
• Records and logs the pings
• Plays back previous logs
• Shows detailed info about the line at the current mouse position when reading a log
• Made in Python! Because that's important, I guess

Screenshots that also showcase my wonderful internet connection:

This is quite useful actually, may I suggest allowing the user to choose what host to ping?

And the delay? And yes, it could be quite useful! ^.^

You made a pretty looking tool I love stuff like this!

I just added a new "settings" window with the features that Eeems and Sorunome requested:

I noticed that you force the user to add http:// to the setting. You could probably do some url parsing to figure out if it's been added or not. It's best to make the user think less when you design things
