Is your Munin not showing Nginx stats? Read to find out how our Support Engineers solve this specific issue.

Recently one of our clients faced a similar situation where their access to the Nginx stats was gone. Our Support Team has come up with an easy way to ensure that they were able to view their data for Nginx status and requests in no time.

Why is Munin not showing Nginx stats?

Munin is a network monitoring tool that allows you to monitor the performance of your networks, systems, server resources, server processes, and so on.

Furthermore, cPanel allows you to utilize the various features offered by Munin via the Munin plugin. You can easily analyze resource trends. It also helps you track down answers to “what just happened to kill our performance?” problems.

How to fix Munin not showing Nginx stats?

Munin utilizes the nginx_status page in order to process the Nginx data. If the Nginx stats are not shown, this solution will come in handy.

1. First, verify that the status page is not working with the following command:

   curl -I http://127.0.0.1/nginx_status
   HTTP/1.1 404 Not Found
   Server: nginx/1.21.1

2. Then, create a new config file as seen below to enable the nginx_status page:

   vi /etc/nginx/conf.d/status.conf

3. Next, add the following lines to the config file created in the previous step:

   server {
          listen 127.0.0.1;
          server_name localhost;
          location /nginx_status {
                  stub_status on;
                  access_log   off;
                  allow 127.0.0.1;
                  deny all;
          }
    }

4. Finally, restart Nginx service with this script:

   /scripts/restartsrv_nginx

You can verify the status page works by running the following commands:

curl -I http://127.0.0.1/nginx_status
HTTP/1.1 200 OK
Server: nginx/1.21.1

After the data accumulates for a few minutes, you will be able to see data for Nginx status as well as requests.
