+# How to change consume command logger
+
+By default `bin/console enqueue:consume` (or `bin/console enqueue:transport:consume`) command prints messages to output.
+The amount of info could be controlled by verbosity option (-v, -vv, -vvv).
+
+In order to change the default logger used by a command you have to register a `LoggerExtension` just before the default one.
+The extension asks you for a logger service, so just pass the one you want to use. 
+Here's how you can do it. 
+
+```yaml
+// config/services.yaml
+
+services:
+    app_logger_extension:
+        class: 'Enqueue\Consumption\Extension\LoggerExtension'
+        public: false
+        arguments: ['@logger']
+        tags:
+            - { name: 'enqueue.consumption.extension', priority: 255 }
+
+```
+
+The logger extension with the highest priority will set its logger.
