How To Monitor Nginx With Amplify

Nginx Amplify is a free monitoring tool for Nginx and Nginx Plus. We can use Amplify to monitor web servers, track our infrastructure assets, monitor the underlying OS, databases, and many other components.

Let’s learn to use NGINX Amplify and monitor the health of our Nginx Server using the functionalities provided by it.

What is Nginx Amplify?

Nginx Amplify is a SaaS (Software-as-a-Service) product, meant for monitoring web servers, databases, infrastructure assets and various other components. It is hosted on AWS public cloud.

Amplify can also be used for various purposes like –

  • Track Web Server/Application’s performance and capabilities.
  • Receiving notifications when there is an issue with infrastructure.
  • We can easily find performance bottlenecks, potential DDoS attacks, or server load, using its visualization related to our Nginx Server.
  • Improving/Optimizing performance of our server using its recommendations and intelligent advice.
  • Keep track of our systems running Nginx Server.

The various key components of Nginx Amplify are:

  • Nginx Amplify Backend – It is the core system component and includes:
    • Core API
    • Analytics Engine
    • Database
    • Metrics Collection Infrastructure
  • Nginx Amplify Web Interface – It is the Web Interface of Amplify that displays various metrics and data collected from the monitored system.
  • Nginx Amplify Agent – An application written in Python, that runs on monitored systems and collects various metrics and data. It also sends that collected information to the Amplify backend, so it can be stored and visualized over the Amplify Web Interface.

Prerequisites for using Nginx Amplify

The prerequisites you need to have, to setup Amplify are:

  • Nginx installed on your server

For this step, you need to know your Amplify API key, it is unique to your account. So, head over to the instructions page we came across before and copy the command similar to the command below, and run it to install the Nginx Amplify Agent.


After you have run the command, the installation script will automatically install the Nginx Amplify Agent package to the server.

As the above image says, we need to use root privileges to change the stub_status configuration file. Firstly, cd into the nginx directory using the below command:

cd /etc/nginx

Now, check whether conf.d files are automatically added to the Nginx configuration, using the below command:

grep -i include\.*conf nginx.conf

Now, create a file named stub_status.conf in the conf.d directory, using the command below:

cat > conf.d/stub_status.conf

Copy and Paste the below content into your stub_status.conf file, which we just created.

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

You can verify whether the changes you have done are successfully applied or not, using the last command from the instructions page, or by simply opening the file again after changing its content.

Now, run the below command so that the changes you have done could be applied, by reloading the Nginx Server.

kill -HUP `cat /var/run/`

Step 5: Modifying the Nginx configuration file

The final step in setting up Amplify Agent, needs to change the Nginx configuration file located at /etc/nginx/nginx.conf , we need to modify 3 sections of the file to complete our setup.

Find the respective attributes and modify them to the given values.

In case, the attributes are commented out, uncomment them and modify them as given below.


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


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


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' ;

Once you are done with modifying the Nginx configuration file, make sure to reload the Nginx Server.
