告警系统邮件引擎运行告警系统

Posted 2020-12-05

一、告警系统邮件引擎

1?在mail目录下创建mail.py文件，
文件内容如下：

#!/usr/bin/env python
#-*- coding: UTF-8 -*-
import os,sys
reload(sys)
sys.setdefaultencoding(‘utf8‘)
import getopt
import smtplib
from email.MIMEText import MIMEText
from email.MIMEMultipart import MIMEMultipart
from  subprocess import *
def sendqqmail(username,password,mailfrom,mailto,subject,content):
    gserver = ‘smtp.163.com‘
    gport = 25
    try:
        msg = MIMEText(unicode(content).encode(‘utf-8‘))
        msg[‘from‘] = mailfrom
        msg[‘to‘] = mailto
        msg[‘Reply-To‘] = mailfrom
        msg[‘Subject‘] = subject
        smtp = smtplib.SMTP(gserver, gport)
        smtp.set_debuglevel(0)
        smtp.ehlo()
        smtp.login(username,password)
        smtp.sendmail(mailfrom, mailto, msg.as_string())
        smtp.close()
    except Exception,err:
        print "Send mail failed. Error: %s" % err
def main():
    to=sys.argv[1]
    subject=sys.argv[2]
    content=sys.argv[3]
##定义QQ邮箱的账号和密码）
    sendqqmail(‘[email protected]‘,‘a123456‘,‘[email protected]‘,to,subject,content)
if __name__ == "__main__":
    main()

首先定义好脚本中的邮箱账号和密码, 脚本执行命令为：python mail.py 目标邮箱 "邮件主题" "邮件内容"
2、在mail目录下创建脚本mail.sh ,当系统服务异常的时候就会调用mail.sh
内容如下：

log=$1
t_s=`date +%s`
t_s2=`date -d "2 hours ago" +%s`
if [ ! -f /tmp/$log ]
then
    echo $t_s2 > /tmp/$log
fi
t_s2=`tail -1 /tmp/$log|awk ‘{print $1}‘`
echo $t_s>>/tmp/$log
v=$[$t_s-$t_s2]
echo $v
if [ $v -gt 3600 ]
then
    ./mail.py  $1  $2  $3
    echo "0" > /tmp/$log.txt
else
    if [ ! -f /tmp/$log.txt ]
    then
        echo "0" > /tmp/$log.txt
    fi
    nu=`cat /tmp/$log.txt`
    nu2=$[$nu+1]
    echo $nu2>/tmp/$log.txt
    if [ $nu2 -gt 10 ]
    then
         ./mail.py  $1 "trouble continue 10 min $2" "$3"
         echo "0" > /tmp/$log.txt
    fi
fi  

二、 运行告警系统

1?暂时关闭掉502
vim /usr/local/bin/mon/conf/mon.conf #0为关闭，1为打开
2?暂时注释掉main.sh脚本中日志行：
vim /usr/local/bin/mon/bin/main.sh
3?执行main.sh
sh -x /usr/local/bin/mon/bin/main.sh

4. 执行load.sh
   bash /usr/local/bin/mon/shares/load.sh
