10## Introduction<a name="section1289063163919"></a>
11
12Hiview is the module of OpenHarmony that provides toolkits for device maintenance across different platforms.
13
14Currently, Hiview opens only the plug-in management platform and system event source capabilities.
15
16**Figure 1**  Architecture of Hiview
17
18![](figures/en-us_image_0000001162020243.png)
19
20Hiview consists of the following components:
21
22adapter: operating system adaptation layer, which adapts APIs of the system services in use
23
24hiview base: Hiview base definition, which provides the plug-in definition, detector definition, and utility class
25
26hiview core: Hiview core module, which provides the plug-in configuration, plug-in management, and event source functions
27
28hiview services: Hiview services. Currently, only the Hiview run information exporting function is provided.
29
30plugins: Independent service modules.
31
32Hiview works in event-driven mode. The core of Hiview is a collection of HiSysEvent stubs distributed in the system.
33
34Formatted events are reported to Hiview through the  **HiSysEvent**  API for processing. Figure 2 shows the data interaction process.

37

39
401. The application framework and system services report system events using the  **HiSysEvent**  API.
41
422. HiSysEventSource reads events and prints the events to logs.

10## 简介<a name="section1289063163919"></a>
11
12Hiview是一个跨平台的终端设备维测服务集。
13
14目前开源部分仅包含插件管理平台和系统事件源。
15
16**图1**.Hiview模块架构图
17
18![](figures/zh-cn_image_0000001162020243.png)
19
20Hiview由框架和插件组成，分别为：
21
22操作系统适配层\(adapter\)，对使用的系统服务的接口进行适配。
23
24Hiview基础定义\(hiview base\)，包括插件的定义，检测器的定义以及工具类。
25
26Hiview的核心模块\(hiview core\)，包括插件配置，插件管理以及事件源。
27
28Hiview服务\(hiview services\)，目前仅包括hiview运行信息导出功能。
29
30Hiview插件\(plugins\)，为独立功能的业务模块。
31
32Hiview维测服务是由事件驱动的，其核心为分布在系统各处的HiSysEvent桩点。
33
34格式化的事件通过HiSysEvent API上报至hiview进行处理，其基本流程如图2。

39
401.应用框架、系统服务使用HiSysEvent组件上报系统事件信息。
41
422.Hiview中HiSysEventSource读取事件，并打印到流水日志中。
