I want to log, every 10 minutes, list of all the apps in Windows that are running, the CPU usage, and memory usage.

I have many node.exe tasks, so I want to see the arguments of the task (for example: node c:\myscript.js)

I tried: tasklist/? but didn't find anything related to CPU usage.

I tried: procexp/? but didn't find any way to export the list to file (or show in a console)

I tried: cprocess (NirSoft), it can dump to file, and show CPU, but it does not give the arguments of the exe that ran.

Any ideas?

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:
    for proc in psutil.process_iter():
            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: enter image description here

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
