Linux下如何通过monit工具监控某个进程并在进程死亡的时候发送邮件通知

1、在安装monit工具之后去到/etc/monit/conf.d/目录下新建文件名为：example.conf的配置文件，内容如下：

check process example matching "python /home/user/sdc/rembg/example.py"
start program = "/home/user/sdc/rembg/example.sh start"
stop program = "/home/user/sdc/rembg/example.sh stop"
if does not exist for 2 cycles then restart
if 1 restarts within 2 cycles then alert

2、打开monit的配置文件：sudo vim /etc/monit/monitrc

3、配置要用到的发送邮件的服务器：

set mailserver smtp.163.com # primary mailserver
port 465
username "your_name@163.com"
password "your_password"
using ssl
with timeout 120 seconds

4、配置邮件格式：

set mail-format {
from: Monit <monit@$HOST>
subject: monit alert -- $EVENT $SERVICE
message: $EVENT Service $SERVICE
Date: $DATE
Action: $ACTION
Host: $HOST
Description: $DESCRIPTION

Your faithful employee,
Monit
}

5、配置发件人：

 set mail-format { from: your_name@163.com }

6、配置收件人：

 set alert recipient@qq.com not on { instance, action }

#、另外如果想开启web页面管理monit用如下配置：

set httpd port 2812 and
use address 192.168.8.4 # only accept connection from localhost (drop if you use M/Monit)
allow * # allow localhost to connect to the server and
allow admin:monit # require user 'admin' with password 'monit'
