# **1.告警系统邮件引擎** #

定义邮件发送的脚本；

[root@yuioplvlinux-128 bin]# cd ../mail/
    [root@yuioplvlinux-128 mail]# vim mail.py
    #!/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，否则你会死的很惨）
        sendqqmail('1234567@163.com','aaaaaaa','1234567@163.com',to,subject,content)
     
    if __name__ == "__main__":
        main()

告警系统的邮件脚本如下：

[root@yuioplvlinux-128 mail]# vim mail.sh
    log=$1
    t_s=`date +%s`   #当前时间的时间戳
    t_s2=`date -d "2 hours ago" +%s`   #2小时前的时间戳
    if [ ! -f /tmp/$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   #计数器置0
    else
        if [ ! -f /tmp/$log.txt ]   #/tmp/$log.txt不存在，则置0
        then
            echo "0" > /tmp/$log.txt
        fi
        nu=`cat /tmp/$log.txt`
        nu2=$[$nu+1]
        echo $nu2>/tmp/$log.txt
        if [ $nu2 -gt 10 ]   #大于10分钟
        then
             ./mail.py  $1 "trouble continue 10 min $2" "$3"
             echo "0" > /tmp/$log.txt
        fi
    fi

# **2.运行系统告警** #

因为502脚本模拟起来比较麻烦，在mon.conf中，将502的脚本监控状态改为0；

to_mon_502=0

且在main.sh中注释该行，如下；

#exec 1>>../log/mon.log 2>>../log/err.log

然后执行主脚本main.sh，执行过程如下：

[root@yuioplvlinux-128 ~]# cd /usr/local/sbin/mon/bin
    [root@yuioplvlinux-128 bin]# sh -x main.sh 
    + export send=1
    + send=1
    ++ grep -A1 'ens33: '
    ++ awk '/inet/ {print $2}'
    ++ /sbin/ifconfig
    + export addr=192.168.30.128
    + addr=192.168.30.128
    ++ pwd
    + dir=/usr/local/sbin/mon/bin
    ++ echo /usr/local/sbin/mon/bin
    ++ awk -F/ '{print $NF}'
    + last_dir=bin
    + '[' bin == bin ']'
    + conf_file=../conf/mon.conf
    ++ date '+%F %T'
    + echo '2018-07-18 22:19:38 load average'
    2018-07-18 22:19:38 load average
    + /bin/bash ../shares/load.sh
    22:19:38 load is 0
    + grep -q to_mon_502=1 ../conf/mon.conf
