23## 简介<a name="section6874544183112"></a>
24
25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。
26
27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。

76### 接口说明<a name="section558917318367"></a>
77
78下面是设备端插件模块对外提供的接口：
79
80- 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。

221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：
222
2231. 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：
224
225 ```
226 message PluginData {
227 int32 pid = 1;
228 string name = 2;
229 uint64 count1 = 3;
230 uint64 count2 = 4;
231 uint64 count3 = 5;
232 ......
233 }
234 ```
235
2362. 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：
237
238 ```
239 message PluginConfig {
240 int32 pid = 1;
241 bool report_interval = 2;
242 int report_counter_id_1 = 3;
243 int report_counter_id_2 = 4;
244 ......
245 }
246 ```
247
2483. 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。
249
250 ```
251 static PluginModuleCallbacks callbacks = {
252 PluginSessionStart,
253 PluginReportResult,
254 PluginSessionStop,
255 };
256 PluginModuleStruct g_pluginModule = {&callbacks, "test-plugin", MAX_BUFFER_SIZE};
257 ```
258
2594. 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。
260
261 ```
262 int PluginSessionStart(const uint8_t* configData, uint32_t configSize)
263 {
264 ......
265 return 0;
266 }
267 ```
268
2695. 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：
270
271 ```
272 int PluginReportResult(uint8_t* bufferData, uint32_t bufferSize)
273 {
274 ......
275 return 0;
276 }
277 ```
278
2796. 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。
280
281 ```
282 int PluginSessionStop()
283 {
284 ......
285 return 0;
286 }
287 ```
288
2897. 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:
290
291 ```
292 action("plugin_cpp_gen") {
293 script = "${OHOS_PROFILER_DIR}/build/protoc.sh" //依赖的编译工具链
294 sources = [ //定义的插件相关的proto文件，比如插件配置文件、插件数据对应的proto文件
295 "plugin_data.proto",
296 "plugin_config.proto",
297 ]
298 outputs = [ //通过protoc编译生成的结果文件
299 "plugin_data.pb.h",
300 "plugin_data.pb.cc",
301 "plugin_config.pb.h",
302 "plugin_config.pb.cc",
303 ]
304 args = [
305 "--cpp_out",
306 "$proto_rel_out_dir",
307 "--proto_path",
308 rebase_path(".", root_build_dir),
309 ]
310 deps = [
311 "${OHOS_PROFILER_3RDPARTY_PROTOBUF_DIR}:protoc(${host_toolchain})",
312 ]
313 }
314 ohos_source_set("plug_cpp") { //将定义的proto文件生成cpp文件
315 deps = [
316 ":plugin_cpp_gen",
317 ]
318 public_deps = [
319 "${OHOS_PROFILER_3RDPARTY_PROTOBUF_DIR}:protobuf",
320 "${OHOS_PROFILER_3RDPARTY_PROTOBUF_DIR}:protobuf_lite",
321 ]
322 include_dirs = [ "$proto_out_dir" ]
323 sources = [ //目标plug_cpp中包括的源文件
324 "plugin_data.pb.h",
325 "plugin_data.pb.cc",
326 "plugin_config.pb.h",
327 "plugin_config.pb.cc",
328 ]
329 }
330 ```
331
3328. 编写插件GN构建脚本:
333
334 ```
335 ohos_shared_library("***plugin") {
336 output_name = "***plugin"
337 sources = [
338 "src/***plugin.cpp", //插件中的源文件
339 ]
340 include_dirs = [
341 "../api/include",
342 "${OHOS_PROFILER_DIR}/device/base/include",
343 ]
344 deps = [
345 "${OHOS_PROFILER_3RDPARTY_PROTOBUF_DIR}:protobuf_lite",
346 "${OHOS_PROFILER_3RDPARTY_PROTOBUF_DIR}:protoc_lib",
347 "${OHOS_PROFILER_DIR}/protos/types/plugins/**:plug_cpp", //上面ohos_source_set中生成的plug_cpp
348 ]
349 install_enable = true
350 subsystem_name = "${OHOS_PROFILER_SUBSYS_NAME}"
351 }
352 ```
353
354
355### 调测验证：<a name="section35362541215"></a>
356
357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。
358
359```
360int main(int argc, char** argv)
361{
362 void* handle;
363 PluginModuleStruct* memplugin;
364 handle = dlopen("./libplugin.z.so", RTLD_LAZY); //动态打开上面生成的插件动态库
365 if (handle == nullptr) {
366 HILOGD("dlopen err:%s.", dlerror());
367 return 0;
368 }
369 memplugin = (PluginModuleStruct*)dlsym(handle, "g_pluginModule"); //获取开发步骤3中定义的g_pluginModule全局变量
370 //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
371 return 0;
372```
373
