Matrix for iOS/macOS
Matrix for android
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.
The monitoring scope of the current tool includes: crash, lag, and out-of-memory, which includes the following two plugins:
-
WCCrashBlockMonitorPlugin: Based on 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.
- 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.
- 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
-
Install via Cocoapods
- Install CocoaPods;
- Run
pod repo update
to make CocoaPods aware of the latest availablematrix
versions; - In your Podfile, add
pod 'matrix-wechat'
to your app target, from the command line, runpod install
; - Use the .xcworkspace file generated by CocoaPods to work on your project;
- Add
#import <Matrix/Matrix.h>
, then you can use the performance probe tool of WeChat.
-
Install with static framework
- Get source code of Matrix;
- Open terminal, execute
make
in thematrix/matrix-iOS
directory to compile and generate static library. After compiling, the iOS platform library is in thematrix/matrix-iOS/build_ios
directory, and the macOS platform library is in thematrix/matrix-iOS/build_macos
directory. - Link with static framework in the project:
- iOS : Use
Matrix.framework
under thematrix/matrix-iOS/build_ios
path, linkMatrix.framework
to the project as a static library; - macOS : Use
Matrix.framework
under thematrix/matrix-iOS/build_macos
path, linkMatrix.framework
to the project as a static library.
- Add
#import <Matrix/Matrix.h>
, then you can use the performance probe tool of WeChat.
In the following places:
- Program
main
function; application:didFinishLaunchingWithOptions:
ofAppDelegate
;- Or other places running as earlier as possible after application launching.
Add a code similar to the following to start the plugin:
#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.
Set pluginListener
of the MatrixBuilder
object, implement the MatrixPluginListenerDelegate
// 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
At this point, Matrix has been integrated into the app and is beginning to collect crash, lag, and out-of-memory data. If you still have questions, check out the example: samples/sample-apple/MatrixDemo

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。
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 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。
- 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
- 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
-
通过 Cocoapods 安装
- 先安装 CocoaPods;
- 通过 pod repo update 更新 matrix 的 Cocoapods 版本;
- 在 Podfile 对应的 target 中,添加 pod 'matrix-wechat',并执行 pod install;
- 在项目中使用 Cocoapods 生成的 .xcworkspace运行工程;
- 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
- 获取 Matrix 源码;
- 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; - 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。
- 添加头文件
#import <Matrix/Matrix.h>
,就可以接入微信的性能探针工具了!
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
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
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
。
Matrix-android 当前监控范围包括:应用安装包大小,帧率变化,启动耗时,卡顿,慢方法,SQLite 操作优化,文件读写,内存泄漏等等。
- APK Checker: 针对 APK 安装包的分析检测工具,根据一系列设定好的规则,检测 APK 是否存在特定的问题,并输出较为详细的检测结果报告,用于分析排查问题以及版本追踪
- Resource Canary: 基于 WeakReference 的特性和 Square Haha 库开发的 Activity 泄漏和 Bitmap 重复创建检测工具
- Trace Canary: 监控界面流畅性、启动耗时、页面切换耗时、慢函数及卡顿等问题
- SQLite Lint: 按官方最佳实践自动化检测 SQLite 语句的使用质量
- IO Canary: 检测文件 IO 问题,包括:文件 IO 监控和 Closeable Leak 监控
与常规的 APM 工具相比,Matrix 拥有以下特点:
- 具有更好的可用性:JAR 包方式提供,更方便应用到持续集成系统中,从而追踪和对比每个 APK 版本之间的变化
- 更多的检查分析功能:除具备 APKAnalyzer 的功能外,还支持统计 APK 中包含的 R 类、检查是否有多个动态库静态链接了 STL 、搜索 APK 中包含的无用资源,以及支持自定义检查规则等
- 输出的检查结果更加详实:支持可视化的 HTML 格式,便于分析处理的 JSON ,自定义输出等等
- 分离了检测和分析部分,便于在不打断自动化测试的前提下持续输出分析后的检测结果
- 对检测部分生成的 Hprof 文件进行了裁剪,移除了大部分无用数据,降低了传输 Hprof 文件的开销
- 增加了重复 Bitmap 对象检测,方便通过减少冗余 Bitmap 数量,降低内存消耗
- 编译期动态修改字节码, 高性能记录执行耗时与调用堆栈
- 准确的定位到发生卡顿的函数,提供执行堆栈、执行耗时、执行次数等信息,帮助快速解决卡顿问题
- 自动涵盖卡顿、启动耗时、页面切换、慢函数检测等多个流畅性指标
- 接入简单,代码无侵入
- 数据量无关,开发、测试阶段即可发现SQLite性能隐患
- 检测算法基于最佳实践,高标准把控SQLite质量*
- 底层是 C++ 实现,支持多平台扩展
- 接入简单,代码无侵入
- 性能、泄漏全面监控,对 IO 质量心中有数
- 兼容到 Android P
- 在你项目根目录下的 gradle.properties 中配置要依赖的 Matrix 版本号,如:
MATRIX_VERSION=0.6.5
- 在你项目根目录下的 build.gradle 文件添加 Matrix 依赖,如:
dependencies {
classpath ("com.tencent.matrix:matrix-gradle-plugin:${MATRIX_VERSION}") { changing = true }
}
- 接着,在 app/build.gradle 文件中添加 Matrix 各模块的依赖,如:
dependencies {
implementation group: "com.tencent.matrix", name: "matrix-android-lib", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-android-commons", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-trace-canary", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-resource-canary-android", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-resource-canary-common", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-io-canary", version: MATRIX_VERSION, changing: true
implementation group: "com.tencent.matrix", name: "matrix-sqlite-lint-android-sdk", version: MATRIX_VERSION, changing: true
}
apply plugin: 'com.tencent.matrix-plugin'
matrix {
trace {
enable = true //if you don't want to use trace canary, set false
baseMethodMapFile = "${project.buildDir}/matrix_output/Debug.methodmap"
blackListFile = "${project.projectDir}/matrixTrace/blackMethodList.txt"
}
}
- 实现 PluginListener,接收 Matrix 处理后的数据, 如:
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
}
}
- 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, 其中参数对应的 key 位于文件 MatrixEnum中, 摘抄部分示例如下:
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
}
}
- 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:
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.
