For any non-technical readers out there, this is probably a post to skip.

Anyone that’s been around Linux for a long time knows that system messages and logs are usually stored in /var/log/messages. Apparently a few versions of Fedora ago, it went away and is now created or managed instead by a program called journalctl.

I was having problems with my Logitech HD Pro Webcam C920 (1080p Widescreen Video Calling and Recording) using it with Bluejeans. Both the webcam and Bluejeans are fantastic tools I recommend. Both worked really well on Fedora 21 with Firefox until some of the more recent kernel updates. The problem I have is that in the midst of a video call my outgoing audio suddenly drops.

So far the problem has not appeared going back to an older kernel version. Right now I’m running kernel-3.17.8-300.fc21.x86_64.

I was able to find some indicators by running journalctl and scrolling through the output; however, I could not figure out how to export the output to save my life so I could share it with someone else and get help. Google and the man page weren’t any help. Asking someone at work I found out that it’s really simple, you just redirect the output!

$ journalctl > dump-of-journalctl.txt

Apparently you can also give it arguments like --since today or --since yesterday.

 

Feeling stuck?
