如何在我的服务器上找到 ProtonMail Bridge PID 文件？

Question

我在我的服务器上安装了 Monit 以及“ProtonMail Bridge”。

我遵循了以下教程：

https://pychao.com/2020/06/10/update-on-using-protonmail-bridge-on-headless-wordpress-linux-servers/

如何知道“ProtonMail Bridge”服务的路径以将其添加到 Monit？

ubuntu@www-example-com ~ $ ps -ef

在此处输入图片描述

这是我的 Monit 配置。ProtonMail Bridge 方不正确：

/var/run/fail2ban/protonmail-bridge.pid

上面那行代码的路径不好，不知道该穿什么来监控ProtonMail Bridge。

$ sudo nano /etc/monit/conf.d/lemp-services

   group login
