A nice little utility to graph my pings

Ping graph

Graph pings in your browser. All it does is great a web server that reads number from the stdout, writes them to a file and every {delay} seconds, sends nice statistics to the client (through websockets).

Why

Because my laptop (which I put under Linux) is quite slow (not because of Linux, but it just so old). So, with my desktop computer (that's under windows), I use it as a sort of web server, where I do all of my dev from. The problem being that when our router started to get slow for some reason (500ms ping), using ssh was somewhat annoying. So, I made this little thing to try to find some patterns and find the culprit on our local network 😄

Example

For now, you have to use a separate utility that pings for you (the awk command is just used to filter everything out and just print the milliseconds)

$ ping 192.168.0.1 | awk  '/from/ { split($7, resArr, "="); print resArr[2] }' | pinggrapher

And if you let it run long enough, you should get something that hopefully has less bars than this:

Options

pinggrapher -help

What's it made of?

A Go file which act as the web server, with ws for the web socket, and some vanilla JavaScript on the front end, with Chart.js for the nice graphs.
