Hi @Mike Assel,   re: connect(log_stdout=False) I learned via a response on Twitter from one of the DevNet genie developers.  After I learned this, I did a scan of the sourcecode and I could not find any reference to this Device() argument either.  Seem like an opportunity for the DevNet team to add more documentation.   re: logging - even though the console logging is disabled, there is still a logfile.  You can find it using the Device.logfile attribute, for example:   In [11]: dev.logfile Out[11]: '/tmp/atlrs21-cli-20191021T024126194.log' I have not experimented with changing the logfile value.   Hope this helps! ...
