# Stdout

## Overview

> [!NOTE]
> Note:
> 
> The stdout connector is provided for testing and debugging purposes.

The Stdout connector logs the SparkplugB metrics to the console’s standard output using a JSON format that represents the Sparkplug payload.

### **Features**

- **Provides a JSON representation of the Sparkplug message payload**
- **Supports filtering using regular expressions (regex)**

## Configuration

The default configuration for the Stdout connector:

```ini
...
# Connectors configuration
[connectors]
  name = "stdout"

# Stdout
[connectors.stdout]
  # Regex pattern to include all metrics
  metric_name_filter = ".*"
```

### Example

Example configuration to capture all metrics with “Temperature” in the name:

```ini
...
# Connectors configuration
[connectors]
  name = "stdout"

# Stdout
[connectors.stdout]
  metric_name_filter = "Temperature"
```
