背景：

购物车相关的站点某些页面经常出现502，如果超过一些阈值则需要报警给管理员知道

.自动发现脚本的编写

# vim /usr/local/zabbix_agents_3.2.0/scripts/store_nginx_code.sh 

#!/bin/bash

# function:monitor store nginx access error code

store_domain_discovery () {

WEB_DOMAIN=($(cat  /usr/local/zabbix_agents_3.2.0/scripts/store_site.txt|grep -v "^#"))

        printf '{\n'

        printf '\t"data":[\n'

for((i=;i<${#WEB_DOMAIN[@]};++i))

    {

    num=$(echo $((${#WEB_DOMAIN[@]}-)))

        if [ "$i" != ${num} ];

            then

        printf "\t\t{ \n"

        printf "\t\t\t\"{#SITENAME}\":\"${WEB_DOMAIN[$i]}\"},\n"

            else

                printf  "\t\t{ \n"

                printf  "\t\t\t\"{#SITENAME}\":\"${WEB_DOMAIN[$num]}\"}]}\n"

        fi

    }

} 

# 统计nginx access log中的50x代码个数

error_code_count () {

    web_site=$

    if [ ${web_site} == 'store.wondershare.jp' ];then

        /usr/bin/cat /data/www/logs/nginx_log/access/${web_site}.access.log |awk '{print $1" "$10" "$11}'|grep 'HTTP/1.1" 50'|uniq |wc -l

.配置编写

vim /usr/local/zabbix_agents_3.2.0/conf/zabbix_agentd/store_domain_discovery.conf

UserParameter=store.domain.discovery,/usr/local/zabbix_agents_3.2.0/scripts/store_nginx_code.sh store_domain_discovery

UserParameter=store.domain.code[*],/usr/local/zabbix_agents_3.2.0/scripts/store_nginx_code.sh error_code_count $
