Configured Info per Load Balancer

Implementation Notes

Fusion feed queries these endpoints on the NGINX+ server:

  • /processes
  • /connections
  • /ssl
  • /requests
  • /upstreams

Server Configuration

Example Configuration

The official NGINX Plus docs have details on how to configure the expanded status module.

Metrics collection: NGINX Plus

The commercial NGINX Plus provides many more metrics through its ngx_http_status_module than are available in open-source NGINX. Among the additional metrics exposed by NGINX Plus are bytes streamed, as well as information about upstream systems and caches. NGINX Plus also reports counts of all HTTP status code types (1xx, 2xx, 3xx, 4xx, 5xx). A sample NGINX Plus status board is available here.

Note: the “Active” connections on the NGINX Plus status dashboard are defined slightly differently than the Active state connections in the metrics collected via the open-source NGINX stub status module. In NGINX Plus metrics, Active connections do not include connections in the Waiting state (aka Idle connections). NGINX Plus also reports metrics in JSON format for easy integration with other monitoring systems. With NGINX Plus, you can see the metrics and health status for a given upstream grouping of servers, or drill down to get a count of just the response codes from a single server in that upstream:


To enable the NGINX Plus metrics dashboard, you can add a status server block inside the http block of your NGINX configuration. See this section on collecting metrics from open-source NGINX for instructions on locating the relevant config files. For example, to set up a status dashboard at http://your.ip.address:8080/status.html and a JSON interface at http://your.ip.address:8080/status, you would add the following server block:

server {
        listen 8080;
        root /usr/share/nginx/html;
        location /status {
        location = /status.html {

The status pages should be live once you reload your NGINX configuration:

nginx -s reload


Setup in Fusion

You can access Fusion Data Feeds from the left navigation pane, under Openmix. For initial steps please refer to the Fusion Integration Documentation.

When you get to the service-specific configuration dialog box, enter the following:

  • Name: The name given to the data feed. This will default to “Service - Platform Name” if not specified.
  • Run Every: The frequency with which the data feed is updated from the service.
  • Platform: The Platform that is associated with the data feed.
  • URL: The URL is an endpoint on the customer’s network that returns the data that the customer wants to see in Openmix.

Once the installation is complete, it will be listed on the Fusion data feeds home page with a green status and monitoring metrics in the log history.

To edit a Fusion data feed click on the data feed in the list and then click the Edit button. Once you have changed the configuration, click Save. This will bring you back to the data feed list with your changes saved and applied to the data feed.
