# SystemLogger

SystemLogger node is used to get
[SystemInformation](https://docs.luxonis.com/software-v3/depthai/depthai-components/messages/system_information.md) of the device.

## How to place it

#### Python

```python
pipeline = dai.Pipeline()
logger = pipeline.create(dai.node.SystemLogger)
```

#### C++

```cpp
dai::Pipeline pipeline;
auto logger = pipeline.create<dai::node::SystemLogger>();
```

## Inputs and Outputs

## Usage

#### Python

```python
pipeline = dai.Pipeline()
logger = pipeline.create(dai.node.SystemLogger)
logger.setRate(1)  # 1 Hz

sysLogQueue = logger.out.createOutputQueue()
```

#### C++

```cpp
dai::Pipeline pipeline;
auto logger = pipeline.create<dai::node::SystemLogger>();
logger->setRate(1.0f);  // 1 Hz

// Send system info to the host via XLink
auto xout = pipeline.create<dai::node::XLinkOut>();
xout->setStreamName("sysinfo");
logger->out.link(xout->input);
```
