What do the black and blue dots mean in the Trace Setup tree?
The dots are there to act as a “path” to help you find the traces and probes you’ve defined. A black dot indicates an entry/exit trace of the marked function, method, file, class, or directory. Functions and methods marked with black dots are represented by equivalent entries in the Wildcards dialog, and are implemented by entries in the trace.cfg file in the workspace. A blue dot indicates a probe or data trace in the marked function, method, file, directory, or class. These actions are not mapped to wildcards, and are implemented by compiled APC for C functions.
