I've managed to configure custom process based on the directory of executable.
Now that I already have the custom process detected, can I make a custom service out of this? Is there any other way to define custom service other than defining entry point method? Any defining-custom-service method that doesn't require me to know or browse through their application packages, class, interface or method?
To create a custom service, the process has to be deep instrumented and only supported technologies can be deep instrumented. If it is a supported technology and is deep instrumented, you have to specify an entry point class and method/methods for the custom service. Can you explain why you want a custom service that is not for a specific application function?
The reason for this is just that if I can create a custom service out of the processes without defining entry points, it would be faster since I don't have to deal with application team/vendor which can take longer time
Unfortunately this can’t be done at this time. You have to specify the entry point class and method/methods to create custom services. The reason for this also is a process could have thousands of classes and methods executed within it. There will be effects on both the process and your Dynatrace environment.
