Your code calls the FFSTProbe function at each specific instrumentation point. All pertinent parameters need to be specified on each call to capture the required data.
As you can see, when you use several calls to the FFSTProbe function, you greatly increase your coding efforts. You need to specify every parameter for each call in order to capture the required error data for problem analysis. This method requires you to change each call to FFSTProbe in your code if you decide to change parameters and is difficult to maintain.
