Error starting up the Python Agent

Hello community,

I'm new to AppDynamics and I'm trying to instrument a simple app using the Python agent, but I'm having some issues in the process. The Agent Proxy is up, but not communicating or sending any data to the controller. I've validated that the settings in the configuration files are correct. The error messages (which continue on a loop) are shown below.
One of the messages coming from the proxy agent is that there's Java isn't able to find jzmq, but I've verified it's actually properly installed in my system (macOS Big Sur 11.6 running on Apple Silicon M1). Is there a way in which I could direct the Java proxy agent to use the path (/usr/local/lib) that holds this library?

Exception in thread "main" java.lang.UnsatisfiedLinkError: no jzmq in java.library.path

ImportError: cannot import name 'constants' from partially initialized module 'appdynamics_bindeps.zmq.backend.cython' (most likely due to a circular import) (/private/tmp/appd/lib/cp39-cp39-1f01d87b92610d5ab8a368411361e151/site-packages/appdynamics_bindeps/zmq/backend/cython/__init__.py)

NameError: name 'appdynamics' is not defined

I'd appreciate any input on this matter, thanks in advance.

Hi @Dylann.Orozco,

I found some info.

There might be some nuggets in here: https://community.appdynamics.com/t5/Dynamic-Languages-Node-JS-Python/Python-Agent-in-python-3-6/m-p/24321

And I also found this To instrument a raw script (without wsgi), you need to use the Python agent API. Here's an example: https://gist.github.com/kylefurlong/920b9824a8c0cf933e416fde5eb040cf

Not sure if this info pertains to exactly your post, but maybe it can lead to further ideas or investigation.
