问题描述
我想咨询个关于连接数的问题，我们用emqx建了一套服务，用ng做了负载，连3个MQTT节点。emqx.conf按照官网文档的指导配置，只加了3个节点的配置信息。目前来看，每个节点都只有1k左右的连接数，用eMQTT-Bench工具做测试，连接数只有2500左右。按照官网文档说明，连接数是不是应该有10万，是不是我们这边有什么配置配错了？
以下是Dash board的截图
emqx.conf 配置文件
NG配置如下
worker_processes 1;
events {
worker_connections 10240;
}
stream {
upstream mqtt_servers {
# down：表示当前的 server 暂时不参与负载
# max_fails：允许请求失败的次数；默认为 1
# fail_timeout：失败超时时间，默认 10s, max_fails 达到次数后暂停的请求时间
# backup：其它所有的非backup机器down或者忙的时候，请求backup机器

server x.x.x.x:12002;

server {

proxy_pass mqtt_servers;
# 启用此项时，对应后端监听器也需要启用 proxy_protocol

#proxy_connect_timeout 10s;
# 默认心跳时间为 10 分钟
#proxy_timeout 1800s;
#proxy_buffer_size 3M;
#tcp_nodelay on;
