Point your browser to /channel.do?sysparm_channel=logtail

What does this load?

This was posted on (now defunct) servicenowgems.com but I have to cover it too.

I was wondering how this worked. This is a logtail for the logs in ServiceNow in the system on the UI pagechannel.do?sysparm_channel=logtail.

This is called via the UI page channel.do which make a GlideAjax request to ChannelAjax. I tried to find all the parts that make this work, and I was able to create a new channel, but I was unable to direct any logs to it. Below are all the exposed files I could find that made this work. This points to channel_stream.do and threads.do which are both black boxed.
