Running Chrome Webrtc Logs

Question

Due to some problem with failing Datachannel (onmessage stop working after 1 hour - approximately 1 GB data send), I was trying to get WebRTC logs on newest Chrome (57) for Windows.

I was trying with official instrction from https://webrtc.org/web-apis/chrome/

chrome.exe --enable-logging --vmodule=*/webrtc/*=2,*/libjingle/*=2,*=-2 --no-sandbox

And with redirected output

--user-data-dir=d:/ChromeRedirected

But without success.

I get chrome_debug.log but without any info from webrtc modules - have any one similar problem ? Are there any resolutions for that ?

It looks like it's "user-data-dir" that's not working. I'm not sure why. — Taylor Brandstetter, Feb 12 '17 at 21:41
Location is working and some logs are available but not for module which I want to get info from — Marcin Zieleźny, Feb 13 '17 at 08:03

After a few weeks of frustration I have get one Mac from my friend and on it everything is working like a charm

Please note that you have to also set v level for entire chrome to get any logs

So correct command for Mac looks like below

open /Applications/Google\ Chrome.app --args --enable-logging --v=4  --vmodule=*/webrtc/*=1

and then logs are posted to

~/Libraries/Application Support/Google/Chrome/chrome_debug.log

It looks like there is a bug in Windows version of chrome which doesn't let you to see any logs from WebRTC.

Still a problem in 2021 :-( – Alexey Doilnitsyn Oct 21 '21 at 18:28 — Alexey Doilnitsyn, Oct 21 '21 at 18:28
