zabbix3.2利用自动发现功能对fastcgi模式的php状态进行集中监控

前端nginx虚拟主机引用后端多个php接口，为了方便监控，将后端服务器集中配置在nginx中，具体配置如下：

[root@eus_nginx:]# cat /usr/local/nginx/config/nginx.conf

            index  index.html index.htm;
        }
 
    location /nginx_status {
            stub_status on;
            access_log off;
            allow 127.0.0.1;
            deny all;
        }
 
    # 集中后端php的状态
        location ~ ^/(back02_status|back02_ping)$
        {
            include fastcgi_params;
            fastcgi_pass 172.20.103.198:;
            fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
        }
        location ~ ^/(back03_status|back03_ping)$
        {
            include fastcgi_params;
            fastcgi_pass 172.20.103.196:;
            fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
        }
        location ~ ^/(back04_status|back04_ping)$
        {
            include fastcgi_params;
            fastcgi_pass 172.20.103.194:;
            fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
        }
        location ~ ^/(back05_status|back05_ping)$
        {
            include fastcgi_params;
            fastcgi_pass 172.20.103.195:;
            fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
        }
        location ~ ^/(back06_status|back06_ping)$
        {
            include fastcgi_params;
            fastcgi_pass 172.20.103.192:;
            fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
        }
        location ~ ^/(back07_status|back07_ping)$
        {
            include fastcgi_params;
            fastcgi_pass 172.20.103.193:;
            fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
        }
 
        #error_page                /.html;
 
        error_page        /50x.html;
        location = /50x.html {
            root   html;
        }
    }
    include vhost.d/*;    
 
}

1.编写自动发现脚本

[root@eus_nginx:/usr/local/zabbix_agents_3.2.0/scripts]# cat back_php_status.sh
#!/bin/bash
# function:monitor php connect status from zabbix 
 
web_ip_discovery () {
WEB_IP=($(cat  /usr/local/zabbix_agents_3.2.0/scripts/php_backs.txt|grep -v "^#"))
        printf '{\n'
        printf '\t"data":[\n'
for((i=;i<${#WEB_IP[@]};++i))
{
num=$(echo $((${#WEB_IP[@]}-)))
        if [ "$i" != ${num} ];
                then
        printf "\t\t{ \n"
        printf "\t\t\t\"{#SITENAME}\":\"${WEB_IP[$i]}\"},\n"
                else
                        printf  "\t\t{ \n"
                        printf  "\t\t\t\"{#SITENAME}\":\"${WEB_IP[$num]}\"}]}\n"
        fi
}
} 
 
web_site_code () {
ip=`echo $|awk -F ':' '{print $1}'`
#echo $ip
curl -s -k --connect-timeout  -m  -o /dev/null -w %{http_code} "http://${ip}"
} 
 
case "$1" in
web_ip_discovery)
web_ip_discovery
;;
web_site_code)
web_site_code $
;;
*) 
 
echo "Usage:$0 {web_ip_discovery|web_site_code [URL]}"
;;
esac

2.需要监控的php连接
[root@eus_nginx:/usr/local/zabbix_agents_3.2.0/scripts]# cat php_backs.txt
127.0.0.1/back02_status:eus_chinasoft_back02
127.0.0.1/back03_status:eus_chinasoft_back03
127.0.0.1/back04_status:eus_chinasoft_back04
127.0.0.1/back05_status:eus_chinasoft_back05
127.0.0.1/back06_status:eus_chinasoft_back06
127.0.0.1/back07_status:eus_chinasoft_back07
172.20.73.207/back09_status:eus_chinasoft_back09
172.20.73.207/back10_status:eus_chinasoft_back10
172.20.73.207/back11_status:eus_chinasoft_back11
172.20.73.207/back12_status:eus_chinasoft_back12
172.20.73.207/back13_status:eus_chinasoft_back13
172.20.73.207/back14_status:eus_chinasoft_back14

3.编写配置文件
# vim /usr/local/zabbix_agents_3.2.0/conf/zabbix_agentd/php_status_ip_discovery.conf

UserParameter=web.ip.discovery,/usr/local/zabbix_agents_3.2.0/scripts/back_php_status.sh web_ip_discovery
UserParameter=web.ip.code[*],/usr/local/zabbix_agents_3.2.0/scripts/back_php_status.sh web_site_code $1

4.zabbix服务端验证
[root@aliyun-american-guigu-zabbix:~]# zabbix_get -s 1.1.1.1 -k 'web.ip.discovery'
{
"data":[
{
"{#SITENAME}":"127.0.0.1/back02_status:eus_chinasoft_back02"},
{
"{#SITENAME}":"127.0.0.1/back03_status:eus_chinasoft_back03"},
{
"{#SITENAME}":"127.0.0.1/back04_status:eus_chinasoft_back04"},
{
"{#SITENAME}":"127.0.0.1/back05_status:eus_chinasoft_back05"},
{
"{#SITENAME}":"127.0.0.1/back06_status:eus_chinasoft_back06"},
{
"{#SITENAME}":"127.0.0.1/back07_status:eus_chinasoft_back07"},
{
"{#SITENAME}":"172.20.73.207/back09_status:eus_chinasoft_back09"},
{
"{#SITENAME}":"172.20.73.207/back10_status:eus_chinasoft_back10"},
{
"{#SITENAME}":"172.20.73.207/back11_status:eus_chinasoft_back11"},
{
"{#SITENAME}":"172.20.73.207/back12_status:eus_chinasoft_back12"},
{
"{#SITENAME}":"172.20.73.207/back13_status:eus_chinasoft_back13"},
{
"{#SITENAME}":"172.20.73.207/back14_status:eus_chinasoft_back14"}]}

[root@aliyun-american-guigu-zabbix:~]# zabbix_get -s 1.1.1.1 -k 'web.ip.code[172.20.73.207/back14_status:eus_chinasoft_back14]'
200

服务端web的配置：

{monitor_back_php_status:web.ip.code[{#SITENAME},].max(#5)}<>200
