Hi @SarahAlidoost , I added the timestamp to logfile suffix. However I found tbparse already provides very nice interface reading logs as DataFrames, see these lines of usages.
For now, I do not see the need to create a utility functions to read log files. Unless you thin the logfile should be read as a specific format? Or maybe I can add the use of tbparse to the example notebook?
