| Field | Description |
|-------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `StartUTC` | The time at which request processing started. |
| `StartLocal` | The local time at which request processing started. |
| `Duration` | The total time taken by processing the response, including the origin server's time but not the log writing time. |
| `FrontendName` | The name of the Traefik frontend. |
| `BackendName` | The name of the Traefik backend. |
| `BackendURL` | The URL of the Traefik backend. |
| `BackendAddr` | The IP:port of the Traefik backend (extracted from `BackendURL`) |
| `ClientAddr` | The remote address in its original form (usually IP:port). |
| `ClientHost` | The remote IP address from which the client request was received. |
| `ClientPort` | The remote TCP port from which the client request was received. |
| `ClientUsername` | The username provided in the URL, if present. |
| `RequestAddr` | The HTTP Host header (usually IP:port). This is treated as not a header by the Go API. |
| `RequestHost` | The HTTP Host server name (not including port). |
| `RequestPort` | The TCP port from the HTTP Host. |
| `RequestMethod` | The HTTP method. |
| `RequestPath` | The HTTP request URI, not including the scheme, host or port. |
| `RequestProtocol` | The version of HTTP requested. |
| `RequestLine` | `RequestMethod` + `RequestPath` + `RequestProtocol` |
| `RequestContentSize` | The number of bytes in the request entity (a.k.a. body) sent by the client. |
| `OriginDuration` | The time taken by the origin server ('upstream') to return its response. |
| `OriginContentSize` | The content length specified by the origin server, or 0 if unspecified. |
| `OriginStatus` | The HTTP status code returned by the origin server. If the request was handled by this Traefik instance (e.g. with a redirect), then this value will be absent. |
| `OriginStatusLine` | `OriginStatus` + Status code explanation |
| `DownstreamStatus` | The HTTP status code returned to the client. |
| `DownstreamStatusLine` | `DownstreamStatus` + Status code explanation |
| `DownstreamContentSize` | The number of bytes in the response entity returned to the client. This is in addition to the "Content-Length" header, which may be present in the origin response. |
| `RequestCount` | The number of requests received since the Traefik instance started. |
| `GzipRatio` | The response body compression ratio achieved. |
| `Overhead` | The processing time overhead caused by Traefik. |
| `RetryAttempts` | The amount of attempts the request was retried. |
