Splunk AppDynamics Python Agent Warning

[Osama_Abbas1]

Hi,

I am using AppD SaaS to monitor an in-house Python-based web application (Flask-based). I have successfully deployed the Python app agent and added the config to supervisor and can get the metrics to the controller properly. However, I get this in the supervisor error log file:

...<output_truncated>
Cannot fetch aiohttp framework version
Cannot fetch aiohttp framework version
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.singularity.ee.util.memory.calc.FieldCache (file:/path/to/.venv/lib/python3.12/site-packages/appdynamics_bindeps/proxy/lib/appagent-boot.jar) to field java.util.Hashtable.table
WARNING: Please consider reporting this to the maintainers of com.singularity.ee.util.memory.calc.FieldCache
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

...<output_truncated>

Don't know what should be done in such case.

Thanks to help.

As long as you see Flask metrics in the Controller, i think you can ignore this warnings.
Warning highlights the agent tries to detect if your app is running on aiohttp, Since you’re using Flask, it just log the warning.
