Summary

Suppose Method Invocation Data Collector (MIDC) parameters are configured for a non-Python Agent business transaction in an application where a Python Agent is also present. Then, Python Agent throws an exception and stops reporting transactions.

This issue can also occur if incorrect MIDC parameters are configured for the Python Agent business transactions.

Affected Software

Applications instrumented with AppDynamics Python Agents (all versions).

Impact

Python applications stop reporting transactions.

Resolution

A fix will be released soon. Until the fix is released, if you use Python Agent for instrumentation in an application, do not use MIDC for any of the agents in the same application. If you already use MIDC, delete it and restart the Python Agent to restore monitoring in the environment.
