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

Adapt the script to your configuration:

url="http://127.0.0.1/status?full"

location ~ ^/(status|ping)$ {
        allow 127.0.0.1;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_index index.php;
        include fastcgi_params;
        #fastcgi_pass 127.0.0.1:9000;
        fastcgi_pass   unix:/var/run/php7.3-fpm.sock;
