## Inspecting and Debugging
+### Built-in Basic Request/Response Logging
+
+Starting with `go-autorest v10.15.0` you can enable basic logging of requests and responses through setting environment variables.
+Setting `AZURE_GO_SDK_LOG_LEVEL` to `LogInfo` will log request/response without their bodies. To include the bodies set the log level to `LogDebug`.
+
+By default the logger writes to strerr, however it can also write to stdout or a file
+if specified in `AZURE_GO_SDK_LOG_FILE`. Note that if the specified file already exists it will be truncated.
+
+**IMPORTANT:** by default the logger will redact the Authorization and Ocp-Apim-Subscription-Key
+headers. Any other secrets will _not_ be redacted.
+
+### Writing Custom Request/Response Inspectors
+
All clients implement some handy hooks to help inspect the underlying requests being made to Azure.
- `RequestInspector`: View and manipulate the go `http.Request` before it's sent
