# APM
|
||
|
||
内存泄露检测
|
||
各家都是基于 Facebook 的 FBRetainCycleDetector 实现，有：
|
||
腾讯 MLeaksFinder
|
||
https://github.com/Tencent/MLeaksFinder
|
||
PLeakSniffer
|
||
https://github.com/music4kid/PLeakSniffer
|
||
LeaksMonitor
|
||
https://github.com/tripleCC/Laboratory/tree/master/LeaksMonitor
|
||
|
||
ANR 检测
|
||
ANR 检测相对比较简单，各家原理基本相同。新建一个 thread 在 threshold 的间隔时间内（一般 200 - 400毫秒）循环等待一个 semaphore，并从主线程 async dispatch semaphore 的 signal 函数，如果超时则报卡顿。

1. https://gist.github.com/mikeash/5172803 这个是纯 GCD 的实现
|
||
2. https://gist.github.com/steipete/5664345 PFPDFKit 里用的是这个
|
||
3. https://gist.github.com/jspahrsummers/419266f5231832602bec GitHub 客户端里用的
|
||
4. https://github.com/wojteklu/Watchdog 这个有用 atomic_store 和 atomic_load 实现死锁回调
|
||
5. DoKit

|
||
|
||
滴滴出行 DoraemonKit
|
||
https://github.com/didi/DoraemonKit
|
||
功能非常多，感觉侧重了 UI 的运行时调试。APM 的部分主要依赖第三方库，如 MLeakFinder。有提供问题上报机制，所以会有不少额外的网络请求发送到 dokit 的API。
|
||
|
||
腾讯 Matrix
|
||
https://github.com/tencent/matrix
|
||
功能精简，只有 ANR 和内存检测。

|
||
监控项目比 DoKit 多，ANR 中能看到主线程堆栈信息，网络层有做一些基本优化指标的监控。
