`tornado.instrumentation.r4` feature flag




I’ve been trying to get the newrelic python agent to work when using Tornado 5 (with UVLoop as well). When debugging my service and getting more into the agent code I saw that there is a new feature flag that is not documented anywhere. The flag is tornado.instrumentation.r4, can you please share with us what is it for? I did enable it and it seems to be working better than tornado.instrumentation.r3 with Tornado 5.



Hey there @amiri - Sorry it’s taking us so long to get back to you. I just wanted to let you know that we are investigating and will get an answer to you as soon as we can. Thanks in advance for your patience!


Any news regarding the matter?
It’s been 6 months…



Hey @amiri - My apologies. This clearly slipped through our cracks. I am grabbing a support engineer to take a look right now.


Hey @amiri, just thought I’d let you know we’ve created a support ticket where we can follow up regarding your question.
