Command line utility to see list of tasks, CPU usage, and memory usage

Personally I would use Python and the lovely psutil library which can gather just about all of the information that you can dream of:

For a process on Windows you can get:

• cpu_percent
• cpu_times
• io_counters
• memory_info
• memory_maps
• num_ctx_switches
• num_handles
• num_threads
• username
• full exe path
• cmdline
• parent
• status
• cwd
• io_counters
• much more
• even more on Linux & OSX

Some Python 3.5+ code to do more or less what you are asking for to the console, (the same can be done with earlier Pythons but not with the f-string):

import psutil
import time
import datetime

while True:
    print(datetime.datetime.now())
    for proc in psutil.process_iter():
        try:
            pr = proc.as_dict()
            print(f'{pr["name"]}\t{pr["memory_percent"]}\t{pr["cpu_percent"]}\t{pr["num_threads"]}\t{" ".join(pr["cmdline"][1:]) if pr["cmdline"] else ""}')
        except (OSError, psutil.AccessDenied):
            print(pr.name(), 'ACCESS DENIED')
    print('\n*** Ctrl-C to Exit ***\n\n')
    time.sleep(600) # Sleep for 10 Mins

On my machine the output looks like:

You could simply pipe the output to a file or you could modify the code to output to a .csv file directly.

• Free, Gratis & Open Source
• Cross Platform
• Flexible

You could do this simply with a batch file, here's something I quickly wrote up,

@echo off
ECHO ***Date and Time***
set datetimef=%date:~-4%_%date:~3,2%_%date:~0,2%__%time:~0,2%_%time:~3,2%_%time:~6,2%
echo %datetimef%
ECHO ***List Processes***
WMIC path win32_process get Caption,Processid,Commandline
ECHO ***CPU-Usage***
wmic cpu get loadpercentage
ECHO ***Memory Usage***
systeminfo | findstr Memory

It's pretty simple, you can tweak it to fit your needs but this meets your requirements. I also see that you want this data exported to a file so you can, output the contents of the batch file like this, batch.bat > Logs-%date:~10,4%%date:~7,2%%date:~4,2%_%time:~0,2%%time:~3,2%.log
