Process resources monitoring application Develop a console application in Python that, for a given process: • periodically gathers process metrics (for a specified amount of time) • creates a report of the gathered process metrics (in CSV format) • outputs the average for each process metric • detects possible memory leaks and raises a warning

Run Command :

python3 src/process_monitor.py 539 5 1 Usage: python script_name.py <process_pid>

Modules : psutil: to get process data psutil.process_iter(['pid', 'name', 'cpu_percent', 'memory_percent', 'num_fds'])

csv: to write CSV File with open(filename, mode='w', newline='') as csvfile: fieldnames = ['Process Name', 'PID', 'CPU Percent', 'Memory Percent'] writer = csv.DictWriter(csvfile, fieldnames=fieldnames)

    writer.writeheader()
    for process_info in process_metrics:
        writer.writerow({
            'Process Name': process_info['name'],
            'PID': process_info['pid'],
            'CPU Percent': process_info['cpu_percent'],
             'Memory Percent': process_info['memory_percent'],
        })

macos commands related to process:

List all the Processes: ps aux ps ef

Output column :

USER PID %CPU %MEM VSZ RSS TT STAT STARTED TIME COMMAND

Print specific column : ps aux | awk '{print $11}' here print $11 will print the 11th column value,

The sort command with -k4,4rn option sorts the output based on the 4th column (memory usage in percentage) in reverse numerical order (-n) to sort it by highest memory usage first, and with r option to sort in descending order.

ps aux | sort -k4,4rn

If you want to see only the top N processes with the highest memory usage, you can use the head command to limit the output:

ps aux | sort -k4,4rn | head -n 10
