告警系统邮件引擎 运行告警系统

告警系统主脚本

vim main.sh

 #!/bin/bash
# 是否发送邮件的开关
export send=1    #定义在所有子脚本里
# 过滤ip地址
export addr=`/sbin/ifconfig |grep -A1 "ens33: "|awk '/inet/ {print $2}'`
dir=`pwd`
# 只需要最后一级目录名
last_dir=`echo $dir|awk -F'/' '{print $NF}'`
# 下面的判断目的是，保证执行脚本的时候，我们在bin目录里，不然监控脚本、邮件和日志很有可能找不到
if [ $last_dir == "bin" ] || [ $last_dir == "bin/" ]; then
    conf_file="../conf/mon.conf"
else
    echo "you shoud cd bin dir"
    exit

/bin/bash ../shares/load.sh
#先检查配置文件中是否需要监控502

告警系统配置文件

vim ../conf/mon.conf

 ## to config the options if to monitor
## 定义mysql的服务器地址、端口以及user、password
to_mon_cdb=0   ##0 or 1, default 0,0 not monitor, 1 monitor
db_ip=10.20.3.13
db_port=3315
db_user=username
db_pass=passwd
## httpd   如果是1则监控，为0不监控
to_mon_httpd=0
## php 如果是1则监控，为0不监控
to_mon_php_socket=0
## http_code_502  需要定义访问日志的路径
to_mon_502=1
logfile=/data/log/xxx.xxx.com/access.log
## request_count   定义日志路径以及域名
to_mon_request_count=0
req_log=/data/log/www.discuz.net/access.log
domainname=www.discuz.net

##定义QQ邮箱的账号和密码

#####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"
