NGINX collector

NGINX is a web server which can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache.

This module will monitor one or more NGINX servers, depending on your configuration.

Requirements

• NGINX with configured ngx_http_stub_status_module.

Metrics

All metrics have "nginx." prefix.

Metric	Scope	Dimensions	Units
connections	global	active	connections
connections_status	global	reading, writing, idle	connections
connections_accepted_handled	global	accepted, handled	connections/s
requests	global	requests	requests/s

Configuration

Edit the go.d/nginx.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d/nginx.conf

Needs only url to server's stub_status. Here is an example for local and remote servers:

jobs:
  - name: local
    url: http://127.0.0.1/stub_status

  - name: remote
    url: http://203.0.113.10/stub_status

For all available options please see module configuration file.

Troubleshooting

To troubleshoot issues with the nginx collector, run the go.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn't working.

• Navigate to the plugins.d directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the plugins setting under [directories].

  cd /usr/libexec/netdata/plugins.d/

• Switch to the netdata user.

  sudo -u netdata -s

• Run the go.d.plugin to debug the collector:

  ./go.d.plugin -d -m nginx
