I've been dealing with an issue with my ISP for some time now where my ping speeds are extremely slow, when they send a tech out he just shurgs his shoulders and say it looks fine now so I asked them if I recorded some statistics on the ping speeds if that would help.
I did this test behind my router and directly connected to the modem.
Essentially I just ran a "ping myisp.com >> pingfile.txt" from my nix box and left it run for about 6 hours or so.
I then took that file and did the following against it so I would just have the ping response times
"cut -d= -f4 | cut -d' ' -f1 >> cut_ping.txt
so that left me with a file that would look like this (a short sample):
So then I wanted to get an average of the ping times (I chose perl to do this), that part was easy, I just read line by line, incremented a counter each time and added the values up - that's the simple math part.
I wanted to determine how many ping response fell into a certain range but for the life of me couldn't figure out how to use the range operator to do this.
What I have works but is ugly as sin.
I looked into Number::Range as well, but really that seems to come down to the same thing, I'd have to define all these ranges and then test my current line against those ranges (unless there's a more elegant way to use it) - which is essentially what I'm doing, I'd likely save myself some simple processing at the end.
Is there a better way to do what I've done?
The output looks like this
