zabbix自动发现 url 以及对http返回状态码监控实现 告警

目的：批量监控业务URL的返回状态码，通过zabbix监控判断业务好坏。

1、zabbix安装

请查看此永久链接：https://www.cnblogs.com/small-wei/p/10911769.html

2、编写监控脚本

cd  /usr/lib/zabbix/externalscripts　　　　　　#本人存放脚本路径，存放路径可以自定义，这个定义文件在zabbix_server.conf中，及zabbix-server服务配置文件。

vim  web_site_code_status.sh

 

#!/bin/bash

source /etc/profile >/dev/null 2>&1
WEB_SITE_discovery () {
        WEB_SITE=($(grep -v "^#" /usr/local/zabbix/etc/zabbix_script.d/WEBURL.txt))
        printf '{\n'
        printf '\t"data":[\n'
for((i=0;i<${#WEB_SITE[@]};++i))
{
                num=$(echo $((${#WEB_SITE[@]}-1)))
                if [[ "$i" != ${num} ]]
                then
                        printf "\t\t{ \n"
                        printf "\t\t\t\"{#SITENAME}\":\"${WEB_SITE[$i]}\"},\n"
                else
                        printf "\t\t{ \n"
                        printf "\t\t\t\"{#SITENAME}\":\"${WEB_SITE[$num]}\"}]}\n"
                fi
}
}

web_site_code () {
#下面注释的是也可以使用域名+端口号
#        host=$(echo "$1"|awk -F "/" '{print $3}')
#   port=$(echo "$1"|awk -F "/" '{print $3}'|awk -F':' '{print $2}')
#   if [[ -z $port ]]
#   then
#       ntlocal="127.0.0.1"
#   else
#       ntlocal="127.0.0.1:$port"
#   fi
#        http_uri=$(echo "$1"|awk -F "/" '{for(i=4;i<=NF;i++) printf "/" $i;printf "\n"}')
#        /usr/bin/curl -H "Host:$host" -o /dev/null -s -w %{http_code} $ntlocal${http_uri}
    /usr/bin/curl -I "$1" 2> /dev/null | grep 'HTTP' | awk '{print $2}'
}

case "$1" in
        web_site_discovery)
                WEB_SITE_discovery
        ;;
        web_site_code)
                web_site_code $2
        ;;
        *)
        echo "Usage:$0 {web_site_discovery|web_site_code URL}"
        ;;
esac

3、创建URL列表

cat  /etc/zabbix/zabbix_script.d/web_url_list.txt     #这个文件在上面的脚本中定义。

www.baidu.com
www.qq.com
www.redhat.com
https://www.redhat.com/en
https://www/zabbix.com

注意：这里也可以在后面加端口号 

4、在zabbix_agentd.conf中添加相关的key

vim  /etc/zabbix/zabbix_agentd.conf      #客户端配置文件中添加&修改如下内容

UnsafeUserParameters=1       #允许将参数中的所有字符传递给用户定义的参数。

UserParameter=web.site.discovery,/usr/lib/zabbix/externalscripts/web_site_code_status.sh web_site_discovery
UserParameter=web.site.code[*],/usr/lib/zabbix/externalscripts/web_site_code_status.sh web_site_code $1

 

5、重启zabbix-agent

Linux6：

service   zabbix-agent  restart

Linux7：

systemctl  restart  zabbix-agent 

6、导入zabbix监控模板文件。

复制如下代码，在本地计算机中创建一个文件：zbx_export_templates.xml （自定义创建）:

<?xml version="1.0" encoding="UTF-8"?>
<zabbix_export>
    <version>3.4</version>
