20.23/20.24/20.25 告警系统邮件引擎 运行告警系统

20.23 20.4 20.4 告警系统邮件引擎(上中下）

shell项目-告警系统mail.sh

1. 创建mail.py脚本 ：

#####脚本使用说明######

#1. 首先定义好脚本中的邮箱账号和密码

#2. 脚本执行命令为：python mail.py 目标邮箱 "邮件主题" "邮件内容"

内容参考https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D22Z/mail.py

[root@aminglinux-128 mon]# vim /usr/local/bin/mon/mail/mail.py

#!/usr/bin/env python
#-*- coding: UTF-8 -*-
import os,sys
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]
##定义邮箱的账号和密码，你需要修改成你自己的账号和密码（请不要把真实的用户名和密码放到网上公开）
sendqqmail('zhuneianxiang@163.com','mima','zhuneianxiang@163.com',to,subject,content)
if __name__ == "__main__":
main()

2. 设定mail.py脚本权限为755 ：

[root@aminglinux-128 mon]#  chmod 755 /usr/local/bin/mon/mail/mail.py

3. 创建mail.sh脚本 ：

mail.sh内容 //其中mail.py内容到这里下载https://coding.net/u/aminglinux/p/aminglinux-book/git/blob/master/D22Z/m b68 ail.py

[root@aminglinux-128 mon]#  vim /usr/local/bin/mon/mail/mail.sh

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

20.26 运行告警系统

1. 暂时关闭掉502：

[root@aminglinux-128 mon]# vim /usr/local/bin/mon/conf/mon.conf

2. 暂时注释掉main.sh脚本中日志行：

[root@aminglinux-128 mon]# vim /usr/local/bin/mon/bin/main.sh

3. 执行main.sh

[root@aminglinux-128 mon]# sh -x /usr/local/bin/mon/bin/main.sh
+ export send=1
+ send=1
+ export addr=ifconfig
+ addr=ifconfig
+ grep -A1 'ens33:  '
+ awk '/inet/ {print $2}'
++ pwd
+ dir=/usr/local/bin/mon
++ awk -F/ '{print $NF}'
++ echo /usr/local/bin/mon
+ last_dir=mon
+ '[' mon == bin ']'
+ '[' mon == bin/ ']'
+ echo 'you shoud cd bin dir'
you shoud cd bin dir
+ exit

4. 执行load.sh

[root@aminglinux-128 mon]# bash /usr/local/bin/mon/shares/load.sh
15:19:08 load is 0
