-## Configuration Options
+## Configuration
 
 ### General
 
 Traefik logs concern everything that happens to Traefik itself (startup, configuration, events, shutdown, and so on).
 
-#### filePath
+#### `filePath`
 
 By default, the logs are written to the standard output.
 You can configure a file path instead using the `filePath` option.
 
-#### format
+```toml tab="File"
+# Writing Logs to a File
+[log]
+  filePath = "/path/to/traefik.log"
+```
+
+```bash tab="CLI"
+# Writing Logs to a File
+--log.filePath="/path/to/traefik.log"
+```
+
+#### `format`
 
 By default, the logs use a text format (`common`), but you can also ask for the `json` format in the `format` option.   
 
-#### log level
+```toml tab="File"
+# Writing Logs to a File, in JSON
+[log]
+  filePath = "/path/to/log-file.log"
+  format   = "json"
+```
+
+```bash tab="CLI"
+# Writing Logs to a File, in JSON
+--log.filePath="/path/to/traefik.log"
+--log.format="json"
+```
+
+#### `level`
+
+By default, the `level` is set to `ERROR`. Alternative logging levels are `DEBUG`, `PANIC`, `FATAL`, `ERROR`, `WARN`, and `INFO`. 
+
+```toml tab="File"
+[log]
+  level = "DEBUG"
+```
 
-By default, the `level` is set to `error`, but you can choose amongst `debug`, `panic`, `fatal`, `error`, `warn`, and `info`.
