**Matrix** is an APM (Application Performance Manage) used in Wechat to monitor, locate and analyse performance problems. It is a **plugin style**, **non-invasive** solution and is currently available on iOS, macOS and Android.

# <a name='matrix_ios_en'> Matrix for iOS/macOS </a>

The monitoring scope of the current tool includes: crash, lag, and out-of-memory, which includes the following two plugins:

* **WCCrashBlockMonitorPlugin：** Based on [KSCrash](https://github.com/kstenerud/KSCrash) framework, it features cutting-edge lag stack capture capabilities with crash capture.

* **WCMemoryStatPlugin：** A performance-optimized out-of-memory monitoring tool that captures memory allocation and the callstack of an application's out-of-memory event.

## Features

#### WCCrashBlockMonitorPlugin

* Easy integration, no code intrusion.
* Determine whether the app is stuck by checking the running status of the Runloop, and support both the iOS and macOS platform.
* Add time-consuming stack fetching, attaching the most time-consuming main thread stack to the thread snapshot log.

#### WCMemoryStatPlugin

* Live recording every object's creating and the corresponding callstack of its creation, and report it when the application out-of-memory is detected.
* Use a balanced binary tree to store living objects and a hash table to store the callstack to optimize performance to the extreme

## Getting Started
#### Install

* **Install via Cocoapods**
  1. Install [CocoaPods](https://guides.cocoapods.org/using/getting-started.html);
  2. Run `pod repo update` to make CocoaPods aware of the latest available `matrix` versions;
  3. In your Podfile, add `pod 'matrix-wechat'` to your app target, from the command line, run `pod install`;
  4. Use the .xcworkspace file generated by CocoaPods to work on your project;
  5. Add `#import <Matrix/Matrix.h>` , then you can use the performance probe tool of WeChat.

* **Install with static framework**
  1. Get source code of Matrix;
  2. Open terminal, execute `make` in the `matrix/matrix-iOS` directory to compile and generate static library. After compiling, the iOS platform library is in the `matrix/matrix-iOS/build_ios` directory, and the macOS platform library is in the `matrix/matrix-iOS/build_macos` directory.
  3. Link with static framework in the project:
    * iOS : Use `Matrix.framework` under the `matrix/matrix-iOS/build_ios` path, link `Matrix.framework` to the project as a static library;
    * macOS : Use `Matrix.framework` under the `matrix/matrix-iOS/build_macos` path, link `Matrix.framework` to the project as a static library.
  4. Add `#import <Matrix/Matrix.h>`, then you can use the performance probe tool of WeChat.

#### Start the plugins

In the following places:

* Program `main` function;
* `application:didFinishLaunchingWithOptions:` of  `AppDelegate`;
* Or other places running as earlier as possible after application launching.

Add a code similar to the following to start the plugin:

```objective-c
#import <Matrix/Matrix.h>
  
Matrix *matrix = [Matrix sharedInstance];
MatrixBuilder *curBuilder = [[MatrixBuilder alloc] init];
curBuilder.pluginListener = self; // get the related event of plugin via the callback of the pluginListener
    
WCCrashBlockMonitorPlugin *crashBlockPlugin = [[WCCrashBlockMonitorPlugin alloc] init];    
[curBuilder addPlugin:crashBlockPlugin]; // add lag and crash monitor.
    
WCMemoryStatPlugin *memoryStatPlugin = [[WCMemoryStatPlugin alloc] init];
[curBuilder addPlugin:memoryStatPlugin]; // add out-of-memory monitor.
    
[matrix addMatrixBuilder:curBuilder];
    
[crashBlockPlugin start]; // start the lag and crash monitor.
// [memoryStatPlugin start];  
// start out-of-memory monitor
// Be careful, WCMemoryStatPlugin has a large performance loss after it is turned on. It is recommended to turn it on as needed.

```

#### Receive callbacks to obtain monitoring data

Set `pluginListener` of the `MatrixBuilder` object, implement the `MatrixPluginListenerDelegate`

```objective-c
// set delegate

MatrixBuilder *curBuilder = [[MatrixBuilder alloc] init];
curBuilder.pluginListener = <object conforms to MatrixPluginListenerDelegate>;

// MatrixPluginListenerDelegate

- (void)onInit:(id<MatrixPluginProtocol>)plugin;
- (void)onStart:(id<MatrixPluginProtocol>)plugin;
- (void)onStop:(id<MatrixPluginProtocol>)plugin;
- (void)onDestroy:(id<MatrixPluginProtocol>)plugin;
- (void)onReportIssue:(MatrixIssue *)issue;
```

Each plugin added to `MatrixBuilder` will call back the corresponding event via `pluginListener`.

**Important: Get the monitoring data of the Matrix via `onReportIssue:`, the data format info reference to [Matrix for iOS/macOS Data Format Description](https://github.com/Tencent/matrix/wiki/Matrix-for-iOS-macOS-Data-Format-Description)**

## Getting Started

1. Configure `MATRIX_VERSION` in gradle.properties.
``` gradle
  MATRIX_VERSION=0.6.6
```

2. Add `matrix-gradle-plugin` in your build.gradle:
``` gradle 
  dependencies {
      classpath ("com.tencent.matrix:matrix-gradle-plugin:${MATRIX_VERSION}") { changing = true }
  }
 
```
3. Add dependencies to your app/build.gradle.

``` gradle
  dependencies {
    implementation group: "com.tencent.matrix", name: "matrix-android-lib", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-android-commons", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-trace-canary", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-resource-canary-android", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-resource-canary-common", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-io-canary", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-sqlite-lint-android-sdk", version: MATRIX_VERSION, changing: true
  }
  
  apply plugin: 'com.tencent.matrix-plugin'
  matrix {
    trace {
        enable = true	//if you don't want to use trace canary, set false
        baseMethodMapFile = "${project.buildDir}/matrix_output/Debug.methodmap"
        blackListFile = "${project.projectDir}/matrixTrace/blackMethodList.txt"
    }
  }
```

4. Implement `PluginListener` to receive data processed by Matrix.

``` java
  public class TestPluginListener extends DefaultPluginListener {
    public static final String TAG = "Matrix.TestPluginListener";
    public TestPluginListener(Context context) {
        super(context);
        
    }

@Override
    public void onReportIssue(Issue issue) {
        super.onReportIssue(issue);
        MatrixLog.e(TAG, issue.toString());
        
        //add your code to process data
    }
}
```

5. Implement `DynamicConfig` to change parameters of Matrix.
``` java
  public class DynamicConfigImplDemo implements IDynamicConfig {
    public DynamicConfigImplDemo() {}

public boolean isFPSEnable() { return true;}
    public boolean isTraceEnable() { return true; }
    public boolean isMatrixEnable() { return true; }
    public boolean isDumpHprof() {  return false;}

@Override
    public String get(String key, String defStr) {
        //hook to change default values
    }

@Override
    public int get(String key, int defInt) {
      //hook to change default values
    }

@Override
    public long get(String key, long defLong) {
        //hook to change default values
    }

@Override
    public boolean get(String key, boolean defBool) {
        //hook to change default values
    }

@Override
    public float get(String key, float defFloat) {
        //hook to change default values
    }
}
```

6. Init Matrix in the ```onCreate``` of your application.

``` java 
  Matrix.Builder builder = new Matrix.Builder(application); // build matrix
  builder.patchListener(new TestPluginListener(this)); // add general pluginListener
  DynamicConfigImplDemo dynamicConfig = new DynamicConfigImplDemo(); // dynamic config
  
  // init plugin 
  IOCanaryPlugin ioCanaryPlugin = new IOCanaryPlugin(new IOConfig.Builder()
                    .dynamicConfig(dynamicConfig)
                    .build());
  //add to matrix               
  builder.plugin(ioCanaryPlugin);
  
  //init matrix
  Matrix.init(builder.build());

// start plugin 
  ioCanaryPlugin.start();
```

**Matrix** 是一款微信研发并日常使用的应用性能接入框架，支持iOS, macOS和Android。
Matrix 通过接入各种性能监控方案，对性能监控项的异常数据进行采集和分析，输出相应的问题分析、定位与优化建议，从而帮助开发者开发出更高质量的应用。

# <a name='matrix_ios_cn'>Matrix for iOS/macOS </a>

当前工具监控范围包括：崩溃、卡顿和爆内存，包含以下两款插件：

* **WCCrashBlockMonitorPlugin：** 基于 [KSCrash](https://github.com/kstenerud/KSCrash) 框架开发，具有业界领先的卡顿堆栈捕获能力，同时兼备崩溃捕获能力。

* **WCMemoryStatPlugin：** 一款性能优化到极致的爆内存监控工具，能够全面捕获应用爆内存时的内存分配以及调用堆栈情况。

## 特性

#### WCCrashBlockMonitorPlugin

* 接入简单，代码无侵入
* 通过检查 Runloop 运行状态判断应用是否卡顿，同时支持 iOS/macOS 平台
* 增加耗时堆栈提取，卡顿线程快照日志中附加最近时间最耗时的主线程堆栈

#### WCMemoryStatPlugin

* 在应用运行期间获取对象存活以及相应的堆栈信息，在检测到应用爆内存时进行上报
* 使用平衡二叉树存储存活对象，使用 Hash Table 存储堆栈，将性能优化到极致

## 使用方法

#### 安装
* **通过 Cocoapods 安装**
  1. 先安装 [CocoaPods](https://guides.cocoapods.org/using/getting-started.html)；
  2. 通过 pod repo update 更新 matrix 的 Cocoapods 版本；
  3. 在 Podfile 对应的 target 中，添加 pod 'matrix-wechat'，并执行 pod install；
  4. 在项目中使用 Cocoapods 生成的 .xcworkspace运行工程；
  5. 在你的代码文件头引入头文件 #import <Matrix/Matrix.h>，就可以接入微信的性能探针工具了！

* **通过静态库安装**
  1. 获取 Matrix 源码；
  2. 打开命令行，在 `matrix/matrix-iOS` 代码目录下执行 `make` 进行编译生成静态库；编译完成后，iOS 平台的库在 `matrix/matrix-iOS/build_ios` 目录下，macOS 平台的库在 `matrix/matrix-iOS/build_macos` 目录下；
  3. 工程引入静态库：
    * iOS 平台：使用 `matrix/matrix-iOS/build_ios` 路径下的 `Matrix.framework`，将 `Matrix.framework` 以静态库的方式引入工程；
    * macOS 平台：使用 `matrix/matrix-iOS/build_macos` 路径下的 `Matrix.framework`，将 `Matrix.framework` 以静态库的方式引入工程。
  4. 添加头文件 `#import <Matrix/Matrix.h>`，就可以接入微信的性能探针工具了！

#### 启动监控

在以下地方：

* 程序 `main` 函数入口；
* `AppDelegate` 中的 `application:didFinishLaunchingWithOptions:`；
* 或者其他应用启动比较早的时间点。

添加类似如下代码，启动插件：

```
#import <Matrix/Matrix.h>
  
Matrix *matrix = [Matrix sharedInstance];
MatrixBuilder *curBuilder = [[MatrixBuilder alloc] init];
curBuilder.pluginListener = self; // pluginListener 回调 plugin 的相关事件
    
WCCrashBlockMonitorPlugin *crashBlockPlugin = [[WCCrashBlockMonitorPlugin alloc] init];    
[curBuilder addPlugin:crashBlockPlugin]; // 添加卡顿和崩溃监控
    
WCMemoryStatPlugin *memoryStatPlugin = [[WCMemoryStatPlugin alloc] init];
[curBuilder addPlugin:memoryStatPlugin]; // 添加内存监控功能
    
[matrix addMatrixBuilder:curBuilder];
    
[crashBlockPlugin start]; // 开启卡顿和崩溃监控
// [memoryStatPlugin start]; 
// 开启内存监控，注意 memoryStatPlugin 开启之后对性能损耗较大，建议按需开启

```

#### 接收回调获得监控数据

设置 MatrixBuilder 对象中的 pluginListener，实现 MatrixPluginListenerDelegate。

```
// 设置 delegate

MatrixBuilder *curBuilder = [[MatrixBuilder alloc] init];
curBuilder.pluginListener = <一个遵循 MatrixPluginListenerDelegate 的对象>;

// MatrixPluginListenerDelegate

各个添加到 MatrixBuilder 的 plugin 会将对应的事件通过 pluginListener 回调。

**重要：通过 `onReportIssue:` 获得 Matrix 处理后的数据，监控数据格式详见：[Matrix for iOS/macOS 数据格式说明](https://github.com/Tencent/matrix/wiki/Matrix-for-iOS-macOS-%E6%95%B0%E6%8D%AE%E6%A0%BC%E5%BC%8F%E8%AF%B4%E6%98%8E)**

## Demo

至此，Matrix 已经集成到应用中并且开始收集崩溃、卡顿和爆内存数据，如仍有疑问，请查看示例：`samples/sample-apple/MatrixDemo`。

# <a name='matrix_android_cn'>Matrix for Android </a>

## 使用方法

1. 在你项目根目录下的 gradle.properties 中配置要依赖的 Matrix 版本号，如：
``` gradle
  MATRIX_VERSION=0.6.6
```

2. 在你项目根目录下的 build.gradle 文件添加 Matrix 依赖，如：
``` gradle 
  dependencies {
      classpath ("com.tencent.matrix:matrix-gradle-plugin:${MATRIX_VERSION}") { changing = true }
  }
```
3. 接着，在 app/build.gradle 文件中添加 Matrix 各模块的依赖，如：
``` gradle
  dependencies {
    implementation group: "com.tencent.matrix", name: "matrix-android-lib", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-android-commons", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-trace-canary", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-resource-canary-android", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-resource-canary-common", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-io-canary", version: MATRIX_VERSION, changing: true
    implementation group: "com.tencent.matrix", name: "matrix-sqlite-lint-android-sdk", version: MATRIX_VERSION, changing: true
  }

apply plugin: 'com.tencent.matrix-plugin'
  matrix {
    trace {
        enable = true	//if you don't want to use trace canary, set false
        baseMethodMapFile = "${project.buildDir}/matrix_output/Debug.methodmap"
        blackListFile = "${project.projectDir}/matrixTrace/blackMethodList.txt"
    }
  }
```

4. 实现 PluginListener，接收 Matrix 处理后的数据, 如：
``` java
  public class TestPluginListener extends DefaultPluginListener {
    public static final String TAG = "Matrix.TestPluginListener";
    public TestPluginListener(Context context) {
        super(context);
        
    }

@Override
    public void onReportIssue(Issue issue) {
        super.onReportIssue(issue);
        MatrixLog.e(TAG, issue.toString());
        
        //add your code to process data
    }
}
```

5. 实现动态配置接口， 可修改 Matrix 内部参数. 在 sample-android 中 我们有个简单的动态接口实例[DynamicConfigImplDemo.java](samples/sample-android/app/src/main/java/sample/tencent/matrix/config/DynamicConfigImplDemo.java), 其中参数对应的 key 位于文件 [MatrixEnum](samples/sample-android/app/src/main/java/sample/tencent/matrix/config/MatrixEnum.java)中， 摘抄部分示例如下：
``` java
  public class DynamicConfigImplDemo implements IDynamicConfig {
    public DynamicConfigImplDemo() {}

@Override
    public String get(String key, String defStr) {
        //hook to change default values
    }

@Override
    public int get(String key, int defInt) {
         //hook to change default values
    }

@Override
    public long get(String key, long defLong) {
        //hook to change default values
    }

@Override
    public boolean get(String key, boolean defBool) {
        //hook to change default values
    }

@Override
    public float get(String key, float defFloat) {
        //hook to change default values
    }
}

```
6. 选择程序启动的位置对 Matrix 进行初始化，如在 Application 的继承类中， Init 核心逻辑如下：
``` java 
  Matrix.Builder builder = new Matrix.Builder(application); // build matrix
  builder.patchListener(new TestPluginListener(this)); // add general pluginListener
  DynamicConfigImplDemo dynamicConfig = new DynamicConfigImplDemo(); // dynamic config
  
  // init plugin 
  IOCanaryPlugin ioCanaryPlugin = new IOCanaryPlugin(new IOConfig.Builder()
                    .dynamicConfig(dynamicConfig)
                    .build());
  //add to matrix               
  builder.plugin(ioCanaryPlugin);
  
  //init matrix
  Matrix.init(builder.build());

// start plugin 
  ioCanaryPlugin.start();
```

至此，Matrix就已成功集成到你的项目中，并且开始收集和分析性能相关异常数据，如仍有疑问，请查看 [示例](https://github.com/Tencent/Matrix/tree/dev/samples/sample-android/).

PS：
Matrix 分析后的输出字段的含义请查看 [Matrix 输出内容的含义解析](https://github.com/Tencent/matrix/wiki/Matrix-Android--data-format)
