Ping-exp

Ping-exp is a small utility which runs a set of ICMP ping experiments simultaneously and then charts the results making it much easier to compare.

Ping-exp example

Links

Features

  • Supports several simultaneous targets (eventually the charts get messy)
  • Ability to control the IP TOS value.
  • Ability to control the ICMP ping size.
  • Ability to save the results to be viewed later.
  • Ability to control the ping frequency and total number.
  • Export to PNG.
  • Interactive inspection (zooming) of the resulting charts (using the Matplotlib viewer).

Requirements

  • Python 2.6 (makes use of the Multiprocessing module).
  • Matplotlib
  • Linux (tested on Fedora. Ping-exp relies on parsing ping’s output so it almost certainly won’t work on Windows – maybe other Unices)

    Hi Dan,

    I get the following error when running the script, first I had to add 3 Targets as I get an error when only using 2.

    Hello Jacques,

    I can’t reproduce your error with two or three destinations. What version of Matplotlib and Python do you have?

    Hello,

    I work for a company that makes a commercial traffic shaper. I am finding your tool an excellent way to experiment and plot different configurations. Thanks for the wonderful tool!

    Been looking for a tool like this for a while
    thanks
    Just wondering if this will work with pinging ipv6 addresses also

    Unfortunately, no. It only knows how to call the ping command not ping6.

    Bogdan, can you please forward your matplotlib and python version information?
