Now we will see in a slightly different approach, as for more special situations, a classic tool is not enough as long as we want to have a more detailed analysis of the behavior of I/O mechanisms.
An example would be to create an infinite loop that copies endlessly (simulation of a demanding process for a long time) a large file (use one of the files obtained previously).
Put the command below in a script:
$ while true; do cp original_file1 copied_file2; done
Use several special monitoring tools for I/O to investigate the state of the system.

Plot a graph with the results obtained with iostat, iotop and one of the previously chosen tools. Interpret the graph and the values obtained using those tools.
