NGINX Monitoring | NGINX Performance Monitoring: Site24x7

Visualize NGINX web server load and performance, and collect key load metrics to track your NGINX instances behavior. Learn how the plugin works.

NGINX performance monitoring metrics:

Accepted connections

The total number of client connections accepted by the NGINX server.

Active connections

The total number of currently active client connections.

Dropped connections

The total number of client connections dropped by the NGINX server.

Idle connections

The total number of currently idle client connections.

Handshakes

The total number of successful SSL handshakes.

Failed handshakes

The total number of failed SSL handshakes.

Current requests

The total number of current client requests.

Total requests

The total number of client requests to the NGINX server.

Reused sessions

The total number of sessions reused by the NGINX server.

Requests by zone backend servers

The total number of requests received by the zone backend servers.

Responses by zone backend servers

The total number of responses sent by the zone backend servers.

Responses/ 1xx, 2xx, 3xx, 4xx, 5xx

The number of responses with status codes 1xx, 2xx, 3xx, 4xx, and 5xx.

How it works?

Log-in to your Site24x7 account. Sign up here if you don't have one.
Download and install the latest version of Site24x7 Linux Agent
Install the NGINX plugin
The agent will execute the NGINX plugin and push the data to the Site24x7 server

Prerequisites:

Ensure that the NGINX server is installed and is up and running
Ensure that the STATUS_URL in the config section is entered correctly

NGINX plugin installation:

Create a directory with the name "nginx", under Site24x7 Linux Agent plugin directory - /opt/site24x7/monagent/plugins/nginx
Download the file "nginx.py" from our GitHub repository and place it under the "nginx" directory
Commands to perform the above step:


      cd /opt/site24x7/monagent/plugins/
      mkdir nginx
      cd nginx
      wget https://raw.githubusercontent.com/site24x7/plugins/master/nginx/nginx.py

Once the plugin file is downloaded, the agent will mark it up in the next data collection and you can view it in Site24x7 client

NGINX plugin configuration:

By default, the plugin will monitor NGINX instance that is configured on "localhost"
In order to change the monitoring configuration, go to plugins directory and edit the "#Config Section:" in nginx.py file


      NGINX plugin file location - /opt/site24x7agent/monagent/plugins/nginx/nginx.py
      #Config Section:
      NGINX_STATUS_URL = "http://localhost/status"

Monitoring additional metrics:

To monitor additional metrics, edit the "nginx.py" file and add the new metrics that need monitoring
Increment the plugin version value in the file "nginx.py" to view the newly added metrics (For e.g. Change the default plugin version from PLUGIN_VERSION = "1" to "PLUGIN_VERSION = "2")
