Great tool :)

I'm using Windows 8.1 and downloaded Python 3.5.0 from https://www.python.org/downloads/windows/.
After installing pinggraph and statistics from pip3, I still got the following error:

After installing colorama via pip3, everything works.

Maybe you could add this to the readme?

gping 127.0.0.1 works as expected, but gping ::1 just gives a blank screen.

When diagnosing network issues, I sometimes open many windows in tmux. Without additional annotation, it's difficult to tell what graph is what host.

I'd like to propose putting the hostname being pinged in a corner of the screen.

I use Windows 8.1 with Python 3.5.0 and get the following error when CTRL+Cing gping:

Traceback (most recent call last):

It's just an esthetic issue, not impairing anything at all. Thought it might be worth reporting.

1. So I fokred the repo and tried to run it on my OS X Yosemite but because of all the annotations it wont work. Python 2 doesnt support them.
2. Is there a way to create perhaps another folder inside the master for python 2, if yes ill try to work on it.

On Linux Mint I get the following error:

Can you give any hints on how this could be solved?

Hi
Installed gping, but does this Graph is ok in Ubuntu 16.04 ?

I've installed gping using snap on an Ubunti 16.04 host with the following cmd:

sudo snap install gping && sudo snap connect gping:network-observe

If i do run

gping -I INTERFACENAME NAME-OF-TARGET

Please check the attached image for the output

I do know that NAME-OF-TARGET is pingable at that moment using classic ping command.

I was hoping to use gping to debug intermittent connectivity issues, by running it on multiple hosts with multiple targets to figure out what part of my network occasionally breaks. However, it seems that if ping packets get lost, the display just stops, rather than showing the lost packets. This effectively means that gping is not usable for the case I had in mind. Would it make sense to explicitly show lost packets (this might need to have a timeout, to consider a packet lost after some time, or after the next reply is received, but probably also needs retroactively updating a packet later when it is received after all.

My system language is russian, so terminal codepage is 866. When i'm trying to run script, i get:
Traceback (most recent call last): File "C:\Anaconda\lib\runpy.py", line 170, in _run_module_as_main "__main__", mod_spec) File "C:\Anaconda\lib\runpy.py", line 85, in _run_code exec(code, run_globals) File "C:\Anaconda\Scripts\gping.exe\__main__.py", line 9, in <module> File "C:\Anaconda\lib\site-packages\gping\pinger.py", line 294, in run _run() File "C:\Anaconda\lib\site-packages\gping\pinger.py", line 281, in _run for ping in it(url): File "C:\Anaconda\lib\site-packages\gping\pinger.py", line 227, in _windows line = ping.stdout.readline().decode() UnicodeDecodeError: 'utf-8' codec can't decode byte 0x8e in position 0: invalid start byte

If change decode() to decode('CP866') or decode('win-1251') it works, but outputs nothing. (And i can't found where to change output encoding). Solution is to run chcp 65001 before executing script. Maybe add this to script by default? (But i don't know how exactly to do this, because subprocess.Popen(["chcp","65001"]) doesn't work - seems that chcp is not executable file.)

Hi there. As the title says, i've just tried the last version under Windows 10 20H2 without success:

gping host = blank window with blinking cursor. Tried with standard cmd shell and the new Windows Terminal: same results.

I'm a Gentoo developer and would like to start distributing this Gentoo. However, it is not yet licensed. Can I recommend GPL-2.

Getting what looks like a regex bug. Running on Mac OSX 10.11 with python 3.5

Since there is apparently a failed match the match is None which is why it errors.

Steps to reproduce: Start gping, resize terminal window vertically until it is very small.

I just started using gping today. Great program. I was playing with the terminal window, trying to figure out how many ms a bar represents at different heights. If I make the terminal too small vertically, it crashes:

Seems like 10 rows works, and less than that it crashes.
I'm running this on Mac with the Terminal app.

Say I wanted to modify it to gcurl for bandwidth plotting. Roughly poll this in the event loop? https://github.com/alexcrichton/curl-rust/blob/65cb1c2c78321a1aedb919ee2b4225879f89f594/curl-sys/lib.rs#L78

Hi. Nice script 👍 !

But, asking for help blocks completely the script:

$ gping -help

(nothing else, it stops here, blocked)

Then it consumes 100% of one core without doing anything:

gping response:

Sorry, my screenshot tool is only taking the top left portion of the screen. The p95 is 1.56ms, which for my connection is impossible.

The same issue occurs with all other hosts.

I noticed we have the license (MIT) specified in Cargo.toml, but it doesn't seem like the license itself has been added to the Rust/new master branch, yet.

Are you planning to publish gping on homebrew ( https://brew.sh/ ) ?
That would ease the process of installing brew, then python 3, and then gping!

Can we do anything to remove flashes on refresh?
Maybe use a terminal command to move cursor to screen top instead of just prints?

So there is a fair bit to do to get to a 0.1 release. Here's a list of things I can think of:

• Look into Drawile (issue #6), seems to be a lot better than the homegrown stuff in gping at the moment.
• Clean up the code. Actually document it and make it readable, probably need to sort out the wtfworthy x/y positioning stuff (sometimes bottom left is 0,0, sometimes top left).
• Add proper command line arguments (issue #25)
• Add a way to reset the graph, or make one/two huge ping spikes not make the graph scale daft (also I think the min number of graph dots is 2 for some reason)
• Support ping whatever | gping
• Possibly make the graph render on a timer rather than when receiving output from ping. Would fix the problem of not having a timeout message from some ping commands but would be more complex.

Because, Debian 😄

(OSX 10.11, python 3.5.0)

Most interactive terminal applications (htop, iftop, nethogs, less) accept the convention of terminating when the user presses the q key.

Python has a curses module in the standard library that might simplify the code a bit and make the graph a bit prettier.

Hi, i know this may be very basic, but would it be possible that you explain how to install gping on MacOS Sierra, i know the OS already have Python 2.6 Installed and I also downloaded and upgraded to 3.5. The "pip3 install pingggraph" works, but when I try to lauch it using "gping 8.8.8.8" it says "-bash: gping: command not found"

Thanks in advance.

Regards!

Windows 10 2004 DE does display a wrong character:

I've just discovered gping, and it's great. It would be even better if there were some simple axis label.

Also, is the current display linear or logarithmic?

Hi, Installed it with cargo. (my os is 64 bit)
when I do gping somehost I only see the blinking cursor in the top left. Normal ping works.
Also tested it as root / with sudo.
here is a demo video: https://youtu.be/RusyEIyL_K4

Thanks for making a snap of gping! It's pretty.

Unfortunately under strict confinement it fails. Looks like you need an extra plug and binary perhaps?

Instead of using statistics.mean that breaks compatibility between python2 and python3, we can simply implement a mean(data) function that returns sum(data)/len(data)

I can send you a PR if you are okay with this.

ZeroDivisionError: division by zero

I restart gping a few times until the first echo response takes 1 or more ms, then gping starts and works as expected.

mtr also has graphs:

Though obviously they are of a different type (and aren't as pretty), they do convey some similar (though more detailed) information.

BTW, I would love an mtr that had an additional display mode that could switch among a set of gping-like graphs for each hop. /CC @traviscross & @rewolf

Hi detailed stats are shown in the animated gif but there doesn't appear to be instructions as to how to enable them?

Using master (commit b2aecf2) I get the following error when trying to run setup.py:

sudo ./setup.py
from: too many arguments
./setup.py: 4: ./setup.py: Syntax error: newline unexpected (expecting ")")

It's probably user error on the installation but snap and pip aren't an option for me.
