# SystemLogger

SystemLogger 节点用于获取设备的 [SystemInformation](https://docs.luxonis.com/software/depthai-components/messages/system_information.md)。

## 如何放置

#### Python

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

#### C++

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

## 输入和输出

## 用法

#### Python

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

# 通过 XLink 将系统信息发送至主机
xout = pipeline.create(dai.node.XLinkOut)
xout.setStreamName("sysinfo")
logger.out.link(xout.input)
```

#### C++

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

// 通过 XLink 将系统信息发送至主机
auto xout = pipeline.create<dai::node::XLinkOut>();
xout->setStreamName("sysinfo");
logger->out.link(xout->input);
```
