How to use gping

Recently, we talked about prettyping, and continuing our mini-series on the different kinds of ping tests, here we’ll talk about gping.

Gping stands for “Graphical ping”; it’s an open source free project. It gives a plot of the ping latency to a host, but the most useful feature is the ability to run concurrent pings to multiple hosts and plot all of them on the same graph. This makes latency comparison easy and intuitive. As an added bonus, it can plot the execution time of CLI commands. Let’s see how all these work.

Installation

The installation instructions for all the supported operating systems (Linux, Windows, MacOS) can be found on the project’s Github page.

I followed the instructions for Linux and I (along the way) I got the following error message:

$ wget -qO - https://azlux.fr/repo.gpg.key | sudo apt-key add -
E: gnupg, gnupg2 and gnupg1 do not seem to be installed, but one of them is required for this operation

As the error suggested I installed gnupg and after that I repeated the steps and it worked as expected. So, for me the Linux installation was as follows:

$ echo "deb http://packages.azlux.fr/debian/ buster main" | sudo tee /etc/apt/sources.list.d/azlux.list
$ apt-get install gnupg
$ wget -qO - https://azlux.fr/repo.gpg.key | sudo apt-key add -
$ apt update
$ apt install gping

As the error suggested I installed gnupg and after that I repeated the steps and it work

I used a fresh Linux box for this test, and gnupg wasn’t installed, but I expect that most of you already have it pre-installed. So, you might not come across this error message.

In addition, on the release page of the project you can find precompiled executables for all the supported operating systems and platforms.

Usage

Gping has very few options as you can see all below:

netbeez$ gping --help
gping 1.2.1-alpha.0
Ping, but with a graph.

USAGE:
    gping [FLAGS] [OPTIONS] [hosts-or-commands]...

FLAGS:
        --cmd      Graph the execution time for a list of commands rather than pinging hosts
    -h, --help     Prints help information
    -4             Resolve ping targets to IPv4 address
    -6             Resolve ping targets to IPv6 address
    -V, --version  Prints version information

OPTIONS:
    -b, --buffer <buffer>            Number of seconds to display in the graph. [default: 30]
    -n, --watch-interval <interval>  Watch interval seconds [default: 0.5]

ARGS:
    <hosts-or-commands>...    Hosts or IPs to ping, or commands to run if --cmd is provided.

If you are looking for the advanced options the regular ping has (e.g. packet size, TOS, ttl) you won’t find them with gping.

It’s basic functionality is to run a basic ping test and get the following output:

netbeez$ gping 1.1.1.

Linux gping

I find the ability to compare latency plots to different hosts really unique and informative. For example, below you see the latency graph to8.8.8.8 and1.1.1.1.Linux gping output

Finally, with the --cmd [command] option you can pass a command to gping, it will execute it, and plot its execution time. Here is the execution-time plot of ls-la:

Linux gping

You can also select your choice of IPv4 or IPv6 resolution, the plot duration, and the interval. For me, the most useful feature is the ability to plot latency results to multiple hosts on the same graph (in the example above, I put just two, but you can have up to a dozen or more if you want).
