Get PID of Browser launched by selenium

Question

I would like to get the PID of the browser launched by selenium. Is there any way to get it done?

Answer 1

I solved it this way:

I am on a Linux OS using Python to detect Firefox memory usage:

import psutil

# Get pid of geckodriver
webdriver_pid = driver.service.process.pid

# Get the process of geckodriver
process = psutil.Process(webdriver_pid)

# Get memory of geckodriver + firefox
# Since memory is in bytes divide by 1024*1024 to obtain result in MB
total_memory = sum([x.memory_info().rss/1048576 for x in process.children() + [process]])
