zabbix使用自动发现功能批量监控服务器端口的可用性

使用自动发现脚本批量监控服务器端口的可用性

.编写自动发现脚本
# cat /usr/local/zabbix_agents_3.2.0/scripts/web_site_code_status.sh
#!/bin/bash

UrlFile="/usr/local/zabbix_agents_3.2.0/scripts/WEB.txt"
IFS=$'\n'

web_site_discovery () {
    WEB_SITE=($(cat $UrlFile|grep -v "^#"))
    printf '{\n'
    printf '\t"data":[\n'
    num=${#WEB_SITE[@]}
    for site in ${WEB_SITE[@]}
    do
        num=$(( $num -  ))
        url=$(echo $site|awk '{print $1}')
        ip=$(echo $site|awk '{print $2}')
        if [ $num -ne  ] ; then
            printf "\t\t{\"{#SITENAME}\":\""%s"\",\"{#PROXYIP}\":\""${ip}"\"},\n" ${url}
        else
            printf "\t\t{\"{#SITENAME}\":\""%s"\",\"{#PROXYIP}\":\""${ip}"\"}\n" ${url}
            printf '\t]\n'
            printf '}\n'
        fi
    done
}

web_site_code () {
/usr/bin/nmap $ -p  >/dev/null | grep -c open
}

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

.需要监控的服务器列表
[root@cbs_logs_master:/usr/local/zabbix_agents_3.2.0/scripts]# cat WEB.txt
ws_cbs_frontend_web01 1.1.1.1
ws_cbs_frontend_web02 1.1.1.2
