I have a server which sends thousands of requests in a minute. This is connected to a Nginx server. Nginx will upstream the requests to 4 servers as per the configuration settings below.upstream cmdc {server cmdc2b:5600 max_fails=3 fail_timeout=30s;server cmdc2a:5600 max_fails=3 fail_timeout=30s;server cmdc1d:5600 max_fails=3 fail_timeout=30s;server cmdc1c:5600 max_fails=3 fail_timeout=30s;keepalive 30;}What I can see from ELK is that almost 50% of requests go to cmdc2b and others are distributed among others. Does anyone suspect any other values which is causing the issue? I am listing my Nginx configuration below.user  nginx;worker_processes  1;error_log  /var/log/nginx/error.log warn;worker_rlimit_nofile 30000;pid        /var/run/nginx.pid;events {    worker_connections  10240;}http {include       /etc/nginx/mime.types;default_type  application/octet-stream;log_format  main  '$remote_addr - $remote_user [$time_local] $request '                  '$status $body_bytes_sent $http_referer '                  '$http_user_agent cachestatus: $upstream_cache_status'    'dest: $upstream_addr'                  ' response_time: $request_time';access_log  /var/log/nginx/access.log  main;sendfile        off;#tcp_nopush     on;keepalive_timeout  65;keepalive_requests 5000;gzip  on;#page will be served using Nginx Gzip Module if requested by clientgzip_http_version 1.1;gzip_vary on;gzip_comp_level 6;gzip_proxied any;gzip_types text/plain text/html text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript application/javascript text/x-js;gzip_buffers 16 8k;gzip_disable MSIE [1-6]\.(?!.*SV1);#error_page--configure the server's statuses when errors occurproxy_cache_path /opt/nds/data/nginx/cache levels=1:2 keys_zone=cmdc_cache:10m max_size=11g loader_threshold=300 loader_files=200 inactive=5m;proxy_cache_key $scheme$request_method$host$request_uri;include /etc/nginx/conf.d/cmdc.conf;}Can someone please put some light here?
Load Balancing is not correct as expected using Nginx
