## 简介<a name="section6874544183112"></a>
|
||
|
||
性能调优组件包含系统和应用调优框架，旨在为开发者提供一套性能调优平台，可以用来分析内存、性能等问题。
|
||
|
||
该组件整体分为PC端和设备端两部分，PC端最终作为deveco studio的插件进行发布，内部主要包括分为UI绘制、设备管理、进程管理、插件管理、数据导入、数据存储、 数据分析、Session管理、配置管理等模块；设备端主要包括命令行工具、服务进程、插件集合、应用程序组件等模块。设备端提供了插件扩展能力，对外提供了插件接口，基于该扩展能力可以按需定义自己的能力，并集成到框架中来，目前基于插件能力已经完成了实时内存插件,trace插件。下文会重点对设备端提供的插件能力进行介绍。

## 说明<a name="section2165102016359"></a>
|
||
|
||
下面针对设备端对外提供的插件扩展能力进行接口和使用说明。
|
||
|
||
### 接口说明<a name="section558917318367"></a>
|
||
|
||
下面是设备端插件模块对外提供的接口：
|
||
|
||
- PluginModuleCallbacks为插件模块对外提供的回调接口，插件管理模块通过该回调接口列表与每一个插件模块进行交互，每一个新增插件都需要实现该接口列表中的函数。

### 使用说明<a name="section681316903611"></a>
|
||
|
||
下面介绍在设备端基于性能调优框架提供的插件能力，新增一个插件涉及到的关键开发步骤：
|
||
|
||
1. 编写proto数据定义文件_plugin\_data.proto_，定义数据源格式，数据源格式决定了插件上报哪些数据：
|
||
|
||
```
|
||
message PluginData {
|
||
int32 pid = 1;
|
||
string name = 2;
|
||
uint64 count1 = 3;
|
||
uint64 count2 = 4;
|
||
uint64 count3 = 5;
|
||
......
|
||
}
|
||
```
|
||
|
||
2. 编写数据源配置文件_plugin\_config.proto_，采集的行为可以根据配置进行变化，可以设置数据源上报间隔等信息：
|
||
|
||
```
|
||
message PluginConfig {
|
||
int32 pid = 1;
|
||
bool report_interval = 2;
|
||
int report_counter_id_1 = 3;
|
||
int report_counter_id_2 = 4;
|
||
......
|
||
}
|
||
```
|
||
|
||
3. 定义PluginModuleCallbacks实现插件回调接口；定义PluginModuleStruct类型的g\_pluginModule全局变量，注册插件信息。
|
||
|
||
```
|
||
static PluginModuleCallbacks callbacks = {
|
||
PluginSessionStart,
|
||
PluginReportResult,
|
||
PluginSessionStop,
|
||
};
|
||
PluginModuleStruct g_pluginModule = {&callbacks, "test-plugin", MAX_BUFFER_SIZE};
|
||
```
|
||
|
||
4. 通过PluginSessionStart（名字可以自己定义）实现插件回调接口列表的onPluginSessionStart接口，主要处理插件的开始流程。
|
||
|
||
```
|
||
int PluginSessionStart(const uint8_t* configData, uint32_t configSize)
|
||
{
|
||
......
|
||
return 0;
|
||
}
|
||
```
|
||
|
||
5. 通过PluginReportResult（名字可以自己定义）实现插件回调接口列表的onPluginReportResult接口，将插件内部采集的信息通过该接口进行上报：
|
||
|
||
```
|
||
int PluginReportResult(uint8_t* bufferData, uint32_t bufferSize)
|
||
{
|
||
......
|
||
return 0;
|
||
}
|
||
```
|
||
|
||
6. 通过PluginSessionStop（名字可以自己定义）实现插件回调接口列表的onPluginSessionStop接口，主要进行插件停止后的操作流程。
|
||
|
||
```
|
||
int PluginSessionStop()
|
||
{
|
||
......
|
||
return 0;
|
||
}
|
||
```
|
||
|
||
7. 编写proto gn构建脚本, 生成protobuf源文件，protobuf源文件编译生成目标文件:
|
||
|
||
```
|
||
action("plugin_cpp_gen") {
|
||
script = "${OHOS_PROFILER_DIR}/build/protoc.sh" //依赖的编译工具链
|
||
sources = [ //定义的插件相关的proto文件，比如插件配置文件、插件数据对应的proto文件
|
||
"plugin_data.proto",
|
||
"plugin_config.proto",
|
||
]
|
||
outputs = [ //通过protoc编译生成的结果文件
|
||
"plugin_data.pb.h",
|
||
"plugin_data.pb.cc",
|
||
"plugin_config.pb.h",
|
||
"plugin_config.pb.cc",
|
||
]
|
||
args = [
|
||
"--cpp_out",
|
||
"$proto_rel_out_dir",
|
||
"--proto_path",
|
||
rebase_path(".", root_build_dir),
|
||
]
|
||
deps = [
|
||
"${OHOS_PROFILER_3RDPARTY_PROTOBUF_DIR}:protoc(${host_toolchain})",
|
||
]
|
||
}
|
||
ohos_source_set("plug_cpp") { //将定义的proto文件生成cpp文件
|
||
deps = [
|
||
":plugin_cpp_gen",
|
||
]
|
||
public_deps = [
|
||
"${OHOS_PROFILER_3RDPARTY_PROTOBUF_DIR}:protobuf",
|
||
"${OHOS_PROFILER_3RDPARTY_PROTOBUF_DIR}:protobuf_lite",
|
||
]
|
||
include_dirs = [ "$proto_out_dir" ]
|
||
sources = [ //目标plug_cpp中包括的源文件
|
||
"plugin_data.pb.h",
|
||
"plugin_data.pb.cc",
|
||
"plugin_config.pb.h",
|
||
"plugin_config.pb.cc",
|
||
]
|
||
}
|
||
```
|
||
|
||
8. 编写插件GN构建脚本:
|
||
|
||
```
|
||
ohos_shared_library("***plugin") {
|
||
output_name = "***plugin"
|
||
sources = [
|
||
"src/***plugin.cpp", //插件中的源文件
|
||
]
|
||
include_dirs = [
|
||
"../api/include",
|
||
"${OHOS_PROFILER_DIR}/device/base/include",
|
||
]
|
||
deps = [
|
||
"${OHOS_PROFILER_3RDPARTY_PROTOBUF_DIR}:protobuf_lite",
|
||
"${OHOS_PROFILER_3RDPARTY_PROTOBUF_DIR}:protoc_lib",
|
||
"${OHOS_PROFILER_DIR}/protos/types/plugins/**:plug_cpp", //上面ohos_source_set中生成的plug_cpp
|
||
]
|
||
install_enable = true
|
||
subsystem_name = "${OHOS_PROFILER_SUBSYS_NAME}"
|
||
}
|
||
```
|
||
|
||
|
||
### 调测验证：<a name="section35362541215"></a>
|
||
|
||
插件动态库生成后，可以自己编写测试代码，通过dlopen加载动态库，并调用上面代码中实现的插件模块回调函数进行验证。
|
||
|
||
```
|
||
int main(int argc, char** argv)
|
||
{
|
||
void* handle;
|
||
PluginModuleStruct* memplugin;
|
||
handle = dlopen("./libplugin.z.so", RTLD_LAZY); //动态打开上面生成的插件动态库
|
||
if (handle == nullptr) {
|
||
HILOGD("dlopen err:%s.", dlerror());
|
||
return 0;
|
||
}
|
||
memplugin = (PluginModuleStruct*)dlsym(handle, "g_pluginModule"); //获取开发步骤3中定义的g_pluginModule全局变量
|
||
//check memplugin->callbacks // 通过该指针调用上面开发步骤3中定义的回调函数
|
||
return 0;
|
||
```

||
