+# Nginx Virtual Host Traffic Input Plugin
+
+This plugin gathers metrics from the [Nginx web server][nginx] using the
+[external virtual host traffic status module][vhts_module]. This module provides
+access to virtual host status information containing the current status of
+servers, upstreams and caches, similar to the live activity monitoring of
+Nginx plus. For module configuration details please see the
+[module documentation][module_doc].
+
+⭐ Telegraf v1.9.0

+
+## 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.md]: ../../../docs/CONFIGURATION.md#plugins
+
+## Configuration
+
+```toml @sample.conf
+# Read Nginx virtual host traffic status module information (nginx-module-vts)
+[[inputs.nginx_vts]]
+  ## An array of ngx_http_status_module or status URI to gather stats.
+  urls = ["http://localhost/status"]
+
+  ## HTTP response timeout (default: 5s)
+  response_timeout = "5s"
+
+  ## 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
+```

+## Example Output
+
+Using this configuration:
+
+```toml
+[[inputs.nginx_vts]]
+  ## An array of Nginx status URIs to gather stats.
+  urls = ["http://localhost/status"]
+```
+
+When run with:
+
+```sh
+./telegraf -config telegraf.conf -input-filter nginx_vts -test
+```
+
+It produces:
