# Nginx Input Plugin

This plugin gathers basic status from the open source web server Nginx. Nginx
Plus is a commercial version. For more information about the differences between
Nginx (F/OSS) and Nginx Plus, see the Nginx [documentation][diff-doc].

## Global configuration options <!-- @/docs/includes/plugin_config.md -->

In addition to the plugin-specific configuration settings, plugins support
additional global and plugin configuration settings. These settings are used to
modify metrics, tags, and field or create aliases and configure ordering, etc.
See the [CONFIGURATION.md][CONFIGURATION.md] for more details.

## Configuration

```toml @sample.conf
# Read Nginx's basic status information (ngx_http_stub_status_module)
[[inputs.nginx]]
  ## An array of Nginx stub_status URI to gather stats.
  urls = ["http://localhost/server_status"]

  ## Optional TLS Config
  # tls_ca = "/etc/telegraf/ca.pem"
  # tls_cert = "/etc/telegraf/cert.pem"
  # tls_key = "/etc/telegraf/key.pem"
  ## Use TLS but skip chain & host verification
  # insecure_skip_verify = false

  ## HTTP response timeout (default: 5s)
  response_timeout = "5s"
```
