# babeltrace2-sink.utils.dummy(7)

Babeltrace 2: Dummy sink component class

## NAME

babeltrace2-sink.utils.dummy - Babeltrace 2: Dummy sink component class

## DESCRIPTION

A Babeltrace 2 **sink.utils.dummy** component consumes messages and discards them (does absolutely nothing with them).

```
            +------------------+
            | sink.utils.dummy |
            |                  |
Messages -->@ in               |
            +------------------+
```

See [**babeltrace2-intro**(7)](/babeltrace2-intro/7.md) to learn more about the Babeltrace 2 project and its core concepts.

A **sink.utils.dummy** sink component can be useful to run a trace processing graph with no sink side effect, for example to perform benchmarks. Prefer a **sink.utils.dummy** component class for such tasks to, for example, a **sink.text.pretty** component and sending its output to **/dev/null**, as a **sink.text.pretty** component still performs formatting operations.

## PORTS

```
+------------------+
| sink.utils.dummy |

```
