It is a way to access the value of the file name pattern used on an Event Source connected to a File Connector from inside the Collectors parse method ? I need this because I have 5 different applications that delivers log events in csv files(they have the same format) but they are missing the information about the application itself. That information I can find from the name(the pattern to be more precise) of the csv file used. This way I can use 1 collector with one File Connector and 5 Event Sources instead of using 5 Collectors.
