Preparing Monitoring Component

Nginx Component

1. Nginx needs to have the ngx_http_stub_status_module module enabled.

2. On each NGINX server, create a status.conf file in the directory that contains other NGINX configuration files (e.g., /usr/local/nginx/conf/):

status.conf

server {
    listen 81;
    server_name localhost;

    access_log off;
    # allow 127.0.0.1;
    # deny all;

    location /nginx_status {
        # Choose your status module

        # freely available with open source NGINX
        stub_status;

        # for open source NGINX < version 1.7.5
        # stub_status on;

        # available only with NGINX Plus
        # status;
    }
}

3. Configure the nginx.conf file by adding the following configuration block within the http section:

nginx.conf

...

http {
    include /usr/local/nginx/conf/status.conf;
}

   • simpleclient
   • simpleclient_common
   • simpleclient_hotspot
   • simpleclient_servlet
   • simpleclient_servlet_common
