This University project involves creating a C program that manages and monitors process executions in a Unix-like system. It features process creation, execution using fork-exec patterns, real-time monitoring through FIFOs (named pipes), and performance analysis by tracking execution times. The project aims to provide practical insights into operating systems' process management and inter-process communication.
This program requires a Unix-like operating system and a C compiler. It has been tested on Ubuntu 20.04.
To build the program, navigate to the main directory and run the following command:
make
To use the monitor, run the monitor executable. Then you'll need to open another terminal and run the tracer executable to execute commands while monitor's running.
The following arguments are supported in the tracer:
execute -u "prog-a arg1 [...] argN"- Executes a program.execute -p "prog-a arg1 [...] argN | prog-b arg1 [...] argN | prog-c arg1 [...] argN"- Executes a pipeline of programs.status- Get the status of all currently executing processes.stats_time;pid1;pid2;...;pidN- Get the total execution time of a set of previously executed processes
