Customizing tick interval in IO Graph

Hi all,

six years ago, a user posted this question about how to change the tick interval in the IO Graph:

"In IO Graph I would like to use tick interval value other than 0.001/0/0.01/0.1/1/10 second like 0.025 second. Is there an add-on somewhere that allows us to specify our own value or do I need to perhaps request that?"

This is exactly what I want to do too. The answer for that was:

"Those values are hard-coded in io_stat.c (look for tick_interval_values). To modify the values a code change is required. As Wireshark is open source, you can build your own version, with values that fit better in your environment."

I am using Wireshark Version 2.4.5 (Git v2.4.5 packaged as 2.4.5-1). It seems that the code files have changed, since I can't find the file io_stat.c in my files.

Does anyone know where I can find the hardcoded tick interval values? (Github-link or something similar)

Or is there any other possibility of customizing the IO Graph tick interval?

I think you probably want to look at io_graph_dialog.cpp now.

Thank you both so much!

I run Wireshark on Ubuntu 18.04 and i installed it from the repos with sudo apt-get wireshark.

Now I don't know where to find the file you mentioned on my system. I tried locate wireshark but couldn't find this certain file or any wireshark - .cpp file at all.

Do you have any solutions?

That just installs the wireshark binary. To customise the binary you will need to modify the source file and rebuild the binary. This is not a trivial exercise if you haven't built a major piece of software before. Instructions for building Wireshark can be found in the Wireshark Developers Guide.
