 1. 安装[standalone pprof](https://github.com/google/pprof)，并把下载的pprof二进制文件路径写入环境变量GOOGLE_PPROF_BINARY_PATH中
 2. 安装llvm-symbolizer（将函数符号转化为函数名），直接用brew安装即可：`brew install llvm`

+# Jemalloc Heap Profiler
+
+## 开启方法
+
+1. 编译[jemalloc](https://github.com/jemalloc/jemalloc)时需--enable-prof以支持profiler, 安装完成后bin目录下会有jeprof文件。
+2. 启动进程前最好配置env `JEPROF_FILE=/xxx/jeprof`，否则进程默认用$PATH里的jeprof解析。
+3. 进程开启profiler：
+  - 启动进程并开启profiler功能：`MALLOC_CONF="prof:true" LD_PRELOAD=/xxx/lib/libjemalloc.so ./bin/test_server`，MALLOC_CONF是env项，prof:true只做一些初始化动作，并不会采样，但[prof_active](https://jemalloc.net/jemalloc.3.html#opt.prof_active)默认是true，所以进程启动就会采样。
+  - 若静态链接jemalloc：`MALLOC_CONF="prof:true" ./bin/test_server`。
+  - 或通过下面的gflags控制，gflags不会反应MALLOC_CONF值。
+4. 相关gflags说明：
+  - FLAGS_je_prof_active：true:开启采样，false:关闭采样。
+  - FLAGS_je_prof_dump：修改值会生成heap文件，用于手动操作jeprof分析。
+  - FLAGS_je_prof_reset：清理已采样数据和重置profiler选项，并且动态设置采样率，[默认](https://jemalloc.net/jemalloc.3.html#opt.lg_prof_sample)2^19B（512K），对性能影响可忽略。
+5. 若要做memory leak:
+  - `MALLOC_CONF="prof:true,prof_leak:true,prof_final:true" LD_PRELOAD=/xxx/lib/libjemalloc.so ./bin/test_server` ，进程退出时生成heap文件。
+  - 注：可`kill pid`优雅退出，不可`kill -9 pid`；可用`FLAGS_graceful_quit_on_sigterm=true FLAGS_graceful_quit_on_sighup=true`来支持优雅退出。
+
+注：
+  - 每次dump的都是从采样至今的所有数据，若触发了reset，接来下dump的是从reset至今的所有数据，方便做diff。
+  - 更多jemalloc profiler选项请参考[官网](https://jemalloc.net/jemalloc.3.html)，如`prof_leak_error:true`则检测到内存泄漏，进程立即退出。

+     - [metadata](https://jemalloc.net/jemalloc.3.html#stats.metadata)
+     - [allocated](https://jemalloc.net/jemalloc.3.html#stats.allocated)：jeprof分析的就是这部分内存。
+     - [active](https://jemalloc.net/jemalloc.3.html#stats.active)：active - allocated ≈ unuse。
+   2. stats.arenas下的：
+     - [resident](https://jemalloc.net/jemalloc.3.html#stats.arenas.i.resident)
+     - [pactive](https://jemalloc.net/jemalloc.3.html#stats.arenas.i.pactive)
