**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 memory, which includes the following three plugins:
* **WCCrashBlockMonitorPlugin：** Based on [KSCrash](https://github.com/kstenerud/KSCrash) framework, it features cutting-edge lag stack capture capabilities with crash capture.
* **WCMemoryStatPlugin：** A memory monitoring tool that captures memory allocation and the callstack of an application's memory event.
* **WCFPSMonitorPlugin：** A fps monitoring tool that captures main thread's callstack while user scrolling.
## 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.
## Getting Started
#### Install
* **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 memory monitor.
WCFPSMonitorPlugin *fpsMonitorPlugin = [[WCFPSMonitorPlugin alloc] init];
[curBuilder addPlugin:fpsMonitorPlugin]; // add fps monitor.
[matrix addMatrixBuilder:curBuilder];
[crashBlockPlugin start]; // start the lag and crash monitor.
[memoryStatPlugin start]; // start memory monitor
[fpsMonitorPlugin start]; // start fps monitor
```
#### 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)**
## Tutorials
At this point, Matrix has been integrated into the app and is beginning to collect crash, lag, and memory data. If you still have questions, check out the example: `samples/sample-iOS/MatrixDemo`.

## Getting Started
***The JCenter repository will stop service on February 1, 2022. So we uploaded Matrix(since 0.8.0) to the MavenCentral repository.***
1. Configure `MATRIX_VERSION` in gradle.properties.
``` gradle
MATRIX_VERSION=2.1.0
```
2. Add `matrix-gradle-plugin` in your build.gradle:
``` gradle
dependencies {
classpath ("com.tencent.matrix:matrix-gradle-plugin:${MATRIX_VERSION}") { changing = true }
}
```
3. Add dependencies to your app/build.gradle.
``` gradle
dependencies {
implementation group: "com.tencent.matrix", name: "matrix-android-lib", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-android-commons", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-trace-canary", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-resource-canary-android", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-resource-canary-common", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-io-canary", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-sqlite-lint-android-sdk", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-battery-canary", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-hooks", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-backtrace", version: MATRIX_VERSION, changing: true
}
apply plugin: 'com.tencent.matrix-plugin'
matrix {
trace {
enable = true //if you don't want to use trace canary, set false
baseMethodMapFile = "${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
}
}
```
Matrix gradle plugin could work with Android Gradle Plugin 3.5.0/4.0.0/4.1.0 currently.
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();
```
For more Matrix configurations, look at the [sample](https://github.com/Tencent/matrix/tree/dev/samples/sample-android).
Note:
1. Since Matrix for Android has migrated to AndroidX since v0.9.0. You may need to add 'android.useAndroidX=true' flag to gradle.properties
2. You can get more about Matrix output at the wiki [The output of Matrix](https://github.com/Tencent/matrix/wiki/Matrix-Android--data-format);
#### Battery Canary Usage
Init BatteryCanary as the following codes:
```java
BatteryMonitorConfig config = new BatteryMonitorConfig.Builder()
.enable(JiffiesMonitorFeature.class)
.enableStatPidProc(true)
.greyJiffiesTime(30 * 1000L)
.setCallback(new BatteryMonitorCallback.BatteryPrinter())
.build();
BatteryMonitorPlugin plugin = new BatteryMonitorPlugin(config);
```
For detail usage, please reference showcase tests at `com.tencent.matrix.batterycanary.ApisTest` or `sample.tencent.matrix.battery.BatteryCanaryInitHelper`.
#### Backtrace Component Usage
How to init backtrace component：
```java
WeChatBacktrace.instance().configure(getApplicationContext()).commit();
```
Then other components in Matrix could use Quikcen Backtrace to unwind stacktrace. See more configuration comments in 'WeChatBacktrace.Configuration'.
#### APK Checker Usage
APK Checker can run independently in Jar ([matrix-apk-canary-2.1.0.jar](https://repo.maven.apache.org/maven2/com/tencent/matrix/matrix-apk-canary/2.1.0/matrix-apk-canary-2.1.0.jar)） mode, usage:

**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>
Matrix-iOS 当前工具监控范围包括：崩溃、卡顿和内存，包含以下三款插件：
* **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：** 一款性能极致的内存监控工具，能够全面捕获应用 OOM 时的内存分配以及调用堆栈情况
* **WCFPSMonitorPlugin：** 一款 FPS 监控工具，当用户滑动界面时，记录主线程调用栈
## 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 OOM 时进行上报
## 使用方法
#### 安装
* **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
WCFPSMonitorPlugin *fpsMonitorPlugin = [[WCFPSMonitorPlugin alloc] init];
[curBuilder addPlugin:fpsMonitorPlugin]; // 添加 fps 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
[fpsMonitorPlugin start]; // 开启 fps 监控
```
#### 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
- (void)onInit:(id<MatrixPluginProtocol>)plugin;
- (void)onStart:(id<MatrixPluginProtocol>)plugin;
- (void)onStop:(id<MatrixPluginProtocol>)plugin;
- (void)onDestroy:(id<MatrixPluginProtocol>)plugin;
- (void)onReportIssue:(MatrixIssue *)issue;
```
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)**

## 使用方法
***由于 JCenter 服务将于 2022 年 2 月 1 日下线，我们已将 Matrix 新版本（>= 0.8.0) maven repo 发布至 MavenCentral。***
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=2.1.0
```
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:${MATRIX_VERSION}") { changing = true }
}
```
3. 接着，在 app/build.gradle 文件中添加 Matrix 各模块的依赖，如：
``` gradle
dependencies {
implementation group: "com.tencent.matrix", name: "matrix-android-lib", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-android-commons", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-trace-canary", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-resource-canary-android", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-resource-canary-common", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-io-canary", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-sqlite-lint-android-sdk", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-battery-canary", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-hooks", version: MATRIX_VERSION, changing: true
}
apply plugin: 'com.tencent.matrix-plugin'
matrix {
trace {
enable = true //if you don't want to use trace canary, set false
baseMethodMapFile = "${project.buildDir}/matrix_output/Debug.methodmap"
blackListFile = "${project.projectDir}/matrixTrace/blackMethodList.txt"
}
}
```
目前 Matrix gradle plugin 支持 Android Gradle Plugin 3.5.0/4.0.0/4.1.0。
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() {}
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. 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.pluginListener(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：
1. 从 v0.9.0 开始，Matrix for Android 迁移到了 AndroidX. 你可能需要添加 'android.useAndroidX=true' 标志到 gradle.properties 文件里。
2. 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)
#### Battery Canary Usage
相关初始化代码如下：
```java
BatteryMonitorConfig config = new BatteryMonitorConfig.Builder()
.enable(JiffiesMonitorFeature.class)
.enableStatPidProc(true)
.greyJiffiesTime(30 * 1000L)
.setCallback(new BatteryMonitorCallback.BatteryPrinter())
.build();
BatteryMonitorPlugin plugin = new BatteryMonitorPlugin(config);
```
具体使用方式，请参考单元测试里相关用例的代码： `com.tencent.matrix.batterycanary.ApisTest` 或 `sample.tencent.matrix.battery.BatteryCanaryInitHelper`.
#### Backtrace Component Usage
如何初始化 backtrace 组件：
```java
WeChatBacktrace.instance().configure(getApplicationContext()).commit();
```
初始化后其他 Matrix 组件就可以使用 Quicken Backtrace 进行回溯。更多参数的配置请查看 WeChatBacktrace.Configuration 的接口注释。
#### APK Checker
APK Check 以独立的 jar 包提供 ([matrix-apk-canary-2.1.0.jar](https://repo.maven.apache.org/maven2/com/tencent/matrix/matrix-apk-canary/2.1.0/matrix-apk-canary-2.1.0.jar)），你可以运行：
```cmd
java -jar matrix-apk-canary-2.1.0.jar
```
查看 Usages 来使用它。
