How to Monitor Nginx with Amplify

Filed Under: NGINX

Amplify is a powerful, lightweight, and intuitive SaaS-based monitoring platform used for monitoring Nginx and Nginx Plus. It monitors and displays Nginx metrics such as

  1. Current connections
  2. Current requests
  3. HTTP errors
  4. HTTP version
  5. Nginx memory usage
  6. Nginx CPU usage
  7. Nginx traffic

In addition, it also monitors the Operating system’s metrics such as CPU usage, Load average, Memory usage, Network traffic, and Swap space. In this guide, we will learn how you can monitor Nginx with Amplify monitoring SaaS platform.


  1. An instance of Nginx installed on a server. Recommended Read: Install Nginx on Ubuntu 18.04
  2. SSH access to the server. Recommended Read: SSH Command in Linux

In this guide, we have an instance of Nginx installed on a CentOS 7 server system (Hostname: spikey).

Let’s jump right in and see how we can monitor Nginx with Amplify.

Step 1: Sign up in Nginx Amplify website

Step 3: Install the Amplify Agent Package

Next, run the second command to install Amplify Agent package

# API_KEY='bf7dfaa516e060f9b3b1fe527d48466d' sh ./

After successfully installing the Amplify agent package, the server will be listed on Amplify and metrics will start being gathered.

Hit the ‘Continue’ button to go to the next step.

Step 4 Hit Continue Button

Step 4: Configure Nginx to visualize crucial metrics

The next page will display another set of instructions as shown. Change your present working directory to /etc/nginx

# cd /etc/nginx

Configure Nginx To Visualize Metrics

Next, verify that conf.d files are automatically added in Nginx configuration

grep -i include\.*conf nginx.conf

Next, create a new file called stub_status.conf

# cat > conf.d/stub_status.conf

Copy and paste the following content into the file

server {
	location /nginx_status {
		stub_status on;
		deny all;

Verify that the stub_status.conf file was added

Sample Output

Check Stub Status Config File Was Added

Next, run the command below to reload Nginx for the stub_status module to become active.

kill -HUP `cat /var/run/`

Relod NGINX Conf

Click on the ‘Continue’ button to proceed to the Next page.

Step 5: Modify the nginx.conf file

The final step will require modifying the /etc/nginx/nginx.conf file. We are specifically going to make adjustments to 3 sections


Ensure that the attribute reads as shown below

error_log /var/log/nginx/error.log warn;

Edit this attribute as shown

access_log /var/log/nginx/access.log main_ext


Finally, make the changes to this attribute as shown

log_format  main_ext  '$remote_addr - $remote_user [$time_local] "$request" '
                       '$status $body_bytes_sent "$http_referer" '
                       '"$http_user_agent" "$http_x_forwarded_for" '
                       '"$host" sn="$server_name" '
                       'rt=$request_time '
                       'ua="$upstream_addr" us="$upstream_status" '
                       'ut="$upstream_response_time" ul="$upstream_response_length" '
                       'cs=$upstream_cache_status' ;

Reload Nginx and click on ‘Finish’ button.

We’re good to go now! Be sure to observe as the metrics start streaming on the graphs as shown
