+# Radius Input Plugin
+
+The Radius plugin collects radius authentication response times.
+
+## 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
+[[inputs.radius]]
+  ## An array of Server IPs and ports to gather from. If none specified, defaults to localhost.
+  servers = ["127.0.0.1:1812","hostname.domain.com:1812"]
+
+  ## Credentials for radius authentication.
+  username = "myuser"
+  password = "mypassword"
+  secret = "mysecret"
+
+  ## Request source server IP, normally the server running telegraf.
+  ## This corresponds to Radius' NAS-IP-Address.
+  # request_ip = "127.0.0.1"
+
+  ## Maximum time to receive response.
+  # response_timeout = "5s"
+```
+
+## Metrics
+
+- radius
+  - tags:
+    - response_code
+    - source
+    - source_port
+  - fields:
+    - responsetime_ms (int64)
+
+## Example Output
+
+```text
+radius,response_code=Access-Accept,source=hostname.com,source_port=1812 responsetime_ms=311i 1677526200000000000
