Logtail a node in ServiceNow# Logtail a node in ServiceNow

This was posted on (now defunct) [servicenowgems.com](http://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 page
`channel.do?sysparm_channel=logtail`.

This is called via the UI page [channel.do](http://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.
