設定 nginx php-fpm status 頁面讀取方式

vi /etc/nginx/conf.d/default.conf

:
location ~ ^/(status|ping)$ {
        allow 127.0.0.1;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_index index.php;
        include fastcgi_params;

systemctl restart nginx

curl http://localhost/status?full
```
正確結果會類似以下訊息<xtermrtf>

至 PHP-FPM 主機內安裝

wget https://github.com/librenms/librenms-agent/raw/master/snmp/phpfpmsp -O /etc/snmp/phpfpmsp
chmod +x /etc/snmp/phpfpmsp

確認 phpfpmsp 可以正確執行
```
/etc/snmp/phpfpmsp
```
如果正確執行應該可以看到類似的訊息<xtermrtf>
