For Developers

As you can see each checmaster rule, in the example configuration json file, have a python package and a function name like checkmaster.sockets.ingoing_port where checkmaster.sockets is the python package and the function is ingoing_port.

This means that you can load and use your own package.function in checkmaster without any changes in the code!
