How to Check the Nginx Status on an Ubuntu Server

How to Check Nginx Status on Ubuntu

Nginx is a powerful server software, reverse proxy, and load balancer that has gained immense popularity due to its performance and scalability.

Whether you’re running a small website or managing a large-scale web application, it’s crucial to monitor the status and health of your web server. This ensures optimal performance and timely resolution of any potential issues.

In this guide, we’ll walk you through the steps to check the status of Nginx on an Ubuntu system.

Let’s get started.

Step 1: Access Your Ubuntu Server

Before you can check the Nginx status, you need to access your Ubuntu server. This can be done using SSH (Secure Shell). Use the following command:

ssh username@your_server_ip_address

Replace username with your Ubuntu username and your_server_ip_address with the IP address of your server.

Step 2: Check if Nginx is Running

To quickly check if Nginx is running, use the following command:

sudo systemctl status nginx

This command will display the current status of the Nginx service. If Nginx is running, you’ll see an “active (running)” status.

For example:

● nginx.service - nginx - high performance web server
   Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
   Active: active (running) since Thu 2023-10-12 08:58:05 UTC; 4 days ago
  Process: 1163 ExecStart=/usr/sbin/nginx -c /etc/nginx/nginx.conf (code=exited, status=0/SUCCESS)
 Main PID: 1190 (nginx)
    Tasks: 10 (limit: 4915)
   CGroup: /system.slice/nginx.service
           ├─1190 nginx: master process /usr/sbin/nginx -c /etc/nginx/nginx.conf
           ├─1191 nginx: worker process
           ├─1192 nginx: worker process
           ├─1193 nginx: worker process
           ├─1194 nginx: worker process
           ├─1195 nginx: worker process
           ├─1196 nginx: worker process
           ├─1197 nginx: worker process
           ├─1198 nginx: worker process
           └─1199 nginx: cache manager process

Step 3: Install Nginx Status Module

Nginx provides a status module that offers real-time data about Nginx’s health and performance. To use this module, you might need to enable it in your Nginx configuration.

Open the Nginx configuration file:

sudo nano /etc/nginx/sites-available/default

Add the following configuration block:

location /nginx_status {
    stub_status on;
    access_log off;
    deny all;

Save and close the file.

Reload Nginx to apply the changes:

sudo systemctl reload nginx

Step 4: View Nginx Status

With the status module enabled, you can view the Nginx status by accessing the /nginx_status location:

curl http://localhost/nginx_status

This will display various metrics, including active connections, reading, writing, waiting connections, and more.

Step 5: Use Third-Party Tools

Monitoring Nginx’s performance and health is crucial for ensuring your web applications run smoothly. While Nginx provides built-in tools for this purpose, third-party solutions can offer enhanced features, more detailed insights, and a user-friendly interface.

Here are some popular third-party tools that can assist you in monitoring Nginx:


nginx-amp is a performance monitoring tool specifically designed for Nginx. It provides real-time metrics and insights into your server’s health and performance. After installing nginx-amp, you can access its dashboard to view real-time metrics. Set up alerts to be notified of any potential issues.


  • Real-time monitoring of Nginx performance metrics.
  • Visualization of traffic patterns and request rates.
  • Alerts for potential issues or performance bottlenecks.
  • Integration with popular alerting and logging systems.



Netdata is an open-source monitoring solution that provides real-time performance and health insights for various systems, including Nginx. Once Netdata is installed on your server, you can access its web interface to view detailed metrics. You can also configure alerts based on specific thresholds or anomalies.


  • Comprehensive dashboard with real-time metrics.
  • Supports monitoring for multiple systems, not just Nginx.
  • Customizable alerts and notifications.
  • Easy integration with other monitoring and alerting systems.

Nginx Plus

Nginx Plus is the commercial version of Nginx, offering advanced features, including enhanced monitoring capabilities. If you’re using Nginx Plus, you can access its built-in monitoring dashboard to view detailed metrics about your server’s performance. This tool also allows for more in-depth configuration and optimization based on the insights provided.


  • Advanced monitoring dashboard with detailed metrics.
  • Real-time tracking of active connections, request rates, and error rates.
  • Health checks and load balancing capabilities.
  • Enhanced security features and support.


Commands Mentioned

  • ssh – Used to access the server remotely.
  • sudo systemctl status nginx – Checks the status of the Nginx service.
  • sudo nano – Opens a file in the nano text editor.
  • sudo systemctl reload nginx – Reloads the Nginx configuration.
  • curl – Fetches content from a URL.


  1. How often should I check the Nginx status?

    It’s advisable to monitor the Nginx status regularly, especially if you’re managing a high-traffic website. Automated monitoring tools can help alert you to any potential issues in real-time.

  2. What does the “waiting” metric in the Nginx status mean?

    The “waiting” metric indicates the number of idle client connections waiting for a request. A high number of waiting connections might suggest that you have more capacity than currently needed.

  3. Why is it important to monitor the Nginx status?

    Monitoring the Nginx status helps in identifying performance bottlenecks, ensuring optimal resource utilization, and proactively addressing potential issues before they impact the user experience.

  4. Can I access the Nginx status from an external IP?

    By default, the Nginx status page is only accessible from the localhost ( If you want to access it externally, you’ll need to modify the “allow” and “deny” directives in the configuration. However, for security reasons, it’s recommended to keep it restricted or protect it with authentication.

  5. Are there any security concerns with enabling the Nginx status module?

    While the Nginx status module provides valuable insights, it can also expose sensitive information about your server’s performance. It’s essential to restrict access to trusted IPs or use authentication to prevent unauthorized access.
