## 概述<a name="section77571101789"></a>

HiSysEvent提供OpenHarmony打点接口，通过在关键路径打点记录系统在运行过程中的重要信息，辅助开发者定位问题，此外还支持开发者将数据上传到云进行大数据质量度量。

## 打点配置<a name="section112771171321"></a>

在进行HiSysEvent事件打点之前，需要先对HiSysEvent事件打点进行配置，具体可参考[《HiSysEvent打点配置指导》](subsys-dfx-hisysevent-write-config.md)。

## 接口说明<a name="section13480315886"></a>

C++打点接口如下：

HiSysEvent类，具体的API详见接口文档 。

## 开发实例<a name="section112771171317"></a>

C++接口实例

1.  源代码开发

    在类定义头文件或者类实现源文件中，包含HiSysEvent头文件：

    ```
    #include "hisysevent.h"
    ```

    假设在业务关注应用启动时间start\_app，在业务类实现相关源文件中使用（调用接口打点）：

    ```
    HiSysEvent::Write(HiSysEvent::Domain::AAFWK, "start_app", HiSysEvent::EventType::FAULT, "app_name", "com.demo");
    ```

2.  编译设置，在BUILD.gn里增加子系统SDK依赖：

    ```
    external_deps = [ "hisysevent_native:libhisysevent" ]
    ```
