Hi @BrikerMan

unfortunately, we don’t yet support pymysql instrumentation, and I’m unfamiliar with its MySQLdb compatibility mode.

While adding support for pymysql would probably be relatively straight forward, we need to be vary to not overload the agent with built-in instrumentations. Every new instrumentation we write needs to be tested, supported and updated, adding a lot of additional load. We are currently looking into ways to add custom module instrumentation without having to depend on built-in instrumentation.
