How to integrate (with AppDynamics) a homemade application created on C++
As far as application performance monitoring is concerned, AppD has a C++ APM agent: https://docs.appdynamics.com/pages/viewpage.action?pageId=45486533
You just need to install it on the server your C++ app is running on and then configure it to report into your controller. Since it is a home made application, you should know the classes and methods so that should make configuring your Business Transactions pretty easy.
This would be through our C++ SDK. We'll be happy to help with the instrumentation in the case you are able to get some APM licenses to try out the SDK.
