Share This:

Monitoring the performance of your web server is essential for ensuring that it runs smoothly and efficiently. NGINX, one of the most popular web servers available today, offers powerful monitoring capabilities through its ngx_http_stub_status_module module. With this module, you can easily monitor your server health in real-time and make sure that your website is always up and running. In this blog post, we’ll take a look at the steps you need to take to enable the NGINX status page in order to monitor your server performance.

First off, you have to check if the NGINX status page is enabled or not. To do this, open up the nginx.conf file by typing “sudo nano /etc/nginx/nginx.conf” in a terminal window. Then add the following line:

# Enable stub_status page
server {
listen 80;
location /nginx_status {
stub_status on;
}
}

Once you’ve added this line, save and close the file. Then restart your NGINX server with this command: “sudo service nginx restart”. After that, you can test if the status page is working by running “curl http://localhost/nginx_status” in a terminal window. If everything went well, it will show an output that contains information about your server performance such as requests per second and uptime.

Enabling NGINX Monitoring

Enabling NGINX monitoring is a simple process that involves a few steps. First, you’ll need to check if the ngx_http_stub_status_module module is enabled in your NGINX server. To do this, open the nginx.conf file and search for the following line “stub_status on;”. If it’s not present, add it at the end of the file and save it.

Next, you’ll need to restart your NGINX server in order to apply the changes made to the configuration file. This can be done using the command “sudo systemctl restart nginx” on Linux systems or “net stop nginx” and “net start nginx” for Windows systems.

Finally, once your NGINX server has been restarted, you can test whether the status page is enabled by visiting http://your-server-address/nginx-status (where your-server-address represents your web server’s address). If everything went well, you should see a page containing information about current connections and other metrics related to the performance of your web server.

Monitoring NGINX with Netdata

Monitoring NGINX with Netdata can be accomplished by utilizing the NGINX plugin. This plugin collects various metrics from NGINX such as requests, total connection time, and more. In order to use this plugin, you first need to make sure that you have the NGINX Netdata module installed. To do this, navigate to the plugins.d directory, which is usually located at /usr/libexec/netdata/plugins.d/. If this isn’t the case on your system, then open netdata.conf and add nginx in the [plugins] section of the file.

Once you have installed the plugin, you will need to switch to the netdata user (sudo -u netdata -s) and run go.d.plugin with debugging mode (-d -m nginx). This will allow you to debug any errors or issues related to your plugin configuration. After that is done, restart your Netdata service and you should be able to monitor your NGINX server performance in real time via the Netdata dashboard or API endpoints.

Viewing Nginx Logs

Nginx logs are stored in the /var/log/nginx/access.log file by default, which is written in the predefined combined format. You can see these logs by opening the file with a text editor or using the command line utility ‘tail’ to view the latest entries. Additionally, you can also modify how these log entries are formatted by editing the NGINX configuration file (located at /etc/nginx/nginx.conf).

Monitoring Nginx Logs

Monitoring Nginx logs is an essential part of ensuring the performance and security of your web applications. To monitor Nginx logs, you will need to enable them in the Nginx configuration file. You can do this by adding the access_log directive to the server block. This will tell Nginx to start logging all requests made to your website. You should also specify a log_file and an optional log_format parameter. Once enabled, you can use a log management tool like Splunk or ELK stack to parse and analyze the logs for any potential issues.

Monitoring Nginx with CloudWatch

Monitoring Nginx with CloudWatch is a simple process. The first step is to attach an IAM role to the instance that you are running Nginx on. This will allow CloudWatch to authenticate and access the server.

Next, install the CloudWatch Logs Agent, which will collect your Nginx logs from all instances in your account. To do this, log into your EC2 instance and run the following command: sudo yum install -y awslogs

Once installed, configure the agent by editing the /etc/awslogs/awslogs.conf file. In this file, add a section for each log file you would like to monitor and specify the location of each log file. For example:

[/var/log/nginx/access_log]
datetime_format = %d/%b/%Y:%H:%M:%S
file = /var/log/nginx/access_log
buffer_duration = 5000
log_stream_name = {instance_id}
initial_position = start_of_file

Finally, start the agent by running the command “sudo service awslogs start” and verify that it is running correctly by running “sudo service awslogs status”. Once configured correctly, CloudWatch will begin monitoring your Nginx logs in real-time and you can view them through the CloudWatch console or API calls.
