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

1.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 ${WEB_SITE[@]}
    do
        num=$(( $num - 1 ))
        url=$(echo $site|awk '{print $1}')
        ip=$(echo $site|awk '{print $2}')
        if [ $num -ne 0 ] ; then
            printf "\t\t{\"{#SITENAME}\":\""%s"\",\"{#PROXYIP}\":\""${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 $1 -p 873 2>/dev/null | grep -c open
}

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


2.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

# 监控选项
[root@cbs_logs_master:/usr/local/zabbix_agents_3.2.0/conf/zabbix_agentd]# more web_site_discovery.conf 
UserParameter=web.site.discovery,/usr/local/zabbix_agents_3.2.0/scripts/web_site_code_status.sh web_site_discovery
UserParameter=web.site.code[*],/usr/local/zabbix_agents_3.2.0/scripts/web_site_code_status.sh web_site_code $1

# 本机测试
[root@cbs_logs_master:/usr/local/zabbix_agents_3.2.0/conf/zabbix_agentd]# /usr/local/zabbix_agents_3.2.0/scripts/web_site_code_status.sh web_site_code 1.1.1.1
1

# zabbix服务端测试
# zabbix_get -s 192.168.11.42 -k 'web.site.code[1.1.1.1]'
