Python APIを使用すると、非常に簡単です。

from selenium import webdriver
browser = webdriver.Firefox()
print browser.binary.process.pid
# browser.binary.process is a Popen object...

Chromeを使用している場合は、もう少し複雑です。chromedriverプロセスを使用します。

c = webdriver.Chrome()
c.service.process # is a Popen instance for the chromedriver process
import psutil
p = psutil.Process(c.service.process.pid)
print p.get_children(recursive=True)

Java では、ChromeDriver を使用する場合、ドライバーが使用するポートを見つけることができます。

port = chromeDriverService.getUrl().getPort();

次に、ポートを使用して、コマンドを実行して chromedriver プロセス ID を見つけることができます

netstat -anp | grep LISTEN | grep [port] (on linux)

また

netstat -aon | findstr LISTENING | findstr [port] (on windows)

さらに進んで、chromedriver プロセス ID (chrome プロセスの親 ID) を使用して、chrome プロセス ID を調べることができます。

ps -efj | grep google-chrome | grep [chromedriverprocessid] (on linux)

また

wmic process get processid,parentprocessid,executablepath | find \"chrome.exe\" |find \"chromeDriverProcessID\"

コードは次のようになります。

running command netstat -anp | grep LISTEN | grep 17132
