unable to instrument - Flask, gevent WSGIServer, gevent.spawn

[cw-mdebi]

Hello,

I have been trying to instrument python process with autodynatrace and not having success. Can you please help and guide on how to get it to work.

I have installed autodynatrace​ python package and are able to see logs in dynatrace​. But it is not getting instrumented to show python process as service or linked log lines. In my observation in dynatrace technology is coming as only docker and python; Oneagent is not getting listed.

I have following type of processes in our app

• Flask based API that uses gevent.pywsgi.WSGIServer

  if condition:
  call_xyz()
  else:
  gevent.spawn(call_xyz)

  • Some process uses above style of code
  • gevent.spawn is used considerably
• Simple python processes that listen to redis messages and trigger calls directly or via gevent.spawn

I have following relevant packages installed

autodynatrace==2.0.0
oneagent-sdk==1.5.0.20221221.150433
Flask==1.1.2
gevent==22.10.2

and have set the following environment variables

AUTOWRAPT_BOOTSTRAP=autodynatrace
AUTODYNATRACE_FORKABLE=True    ## Tried changing it to True / False, but with limited success.

I understand that we can either instrument parent or child process. I guess gevent.spawn will have impact here?

I ran the troubleshooting guide from sdk page - https://github.com/Dynatrace/OneAgent-SDK-for-Python#troubleshooting - it seems to work and output is follows. However, when I run python process, I do not see any autodynatrace log in flask process output even after tweaking AUTODYNATRACE_LOG_LEVEL .
