Posted 2020-11-10

cd /usr/local/sbin mkdir mon cd mon mkdir bin conf shares mail log cd bin vim main.sh

一、shell项目-告警系统main.sh?

main.sh内容

#!/bin/bash
#Written by chinantfy.
# 是否发送邮件的开关
export send=1
# 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
fi
exec 1>>../log/mon.log 2>>../log/err.log
echo "`date +"%F %T"` load average"
/bin/bash ../shares/load.sh
#先检查配置文件中是否需要监控502
if grep -q ‘to_mon_502=1‘ $conf_file; then
    export log=`grep ‘logfile=‘ $conf_file |awk -F ‘=‘ ‘{print $2}‘ |sed ‘s/ //g‘`
    /bin/bash??../shares/502.sh
fi

cd ../conf
vim mon.conf

二、shell项目-告警系统mon.conf?

mon.conf内容

## 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

cd ../shares
vim load.sh

三、shell项目-告警系统load.sh

load.sh内容

#! /bin/bash
##Writen by chinantfy##
load=`uptime |awk -F ‘average:‘ ‘{print $2}‘|cut -d‘,‘ -f1|sed ‘s/ //g‘ |cut -d. -f1`
if [ $load -gt 10 ] && [ $send -eq "1" ]
then
    echo "$addr `date +%T` load is $load" >../log/load.tmp
    /bin/bash ../mail/mail.sh [email protected] "$addr\_load:$load" `cat ../log/load.tmp`
fi
echo "`date +%T` load is $load"

vim 502.sh

四、shell项目-告警系统502.sh

502.sh内容

#! /bin/bash
d=`date -d "-1 min" +%H:%M`
c_502=`grep :$d:  $log   |grep ‘ 502 ‘|wc -l`
if [ $c_502 -gt 10 ] && [ $send == 1 ]; then
     echo "$addr $d 502 count is $c_502">../log/502.tmp
     /bin/bash ../mail/mail.sh $addr\_502 $c_502   ../log/502.tmp
fi
echo "`date +%T` 502 $c_502"

vim disk.sh

五、shell项目-告警系统disk.sh

disk.sh内容

#! /bin/bash
##Writen by chinantfy##
rm -f ../log/disk.tmp
for r in `df -h |awk -F ‘[ %]+‘ ‘{print $5}‘|grep -v Use`
do
? ? if [ $r -gt 90 ] && [ $send -eq "1" ]
then
? ? echo "$addr `date +%T` disk useage is $r" >>../log/disk.tmp
fi
if [ -f ../log/disk.tmp ]
then
? ? df -h >> ../log/disk.tmp
? ? /bin/bash ../mail/mail.sh $addr\_disk $r ../log/disk.tmp
? ? echo "`date +%T` disk useage is nook"
else
? ? echo "`date +%T` disk useage is ok"
