--heap-prof
稳定性: 1 - 实验
在启动时开始 V8 堆分析器,并在退出前将堆分析器写入磁盘。
如果未指定--heap-prof-dir
,则生成的分析文件放在当前工作目录中。
如果未指定 --heap-prof-name
,则生成的分析文件名为 Heap.${yyyymmdd}.${hhmmss}.${pid}.${tid}.${seq}.heapprofile
。
$ node --heap-prof index.js
$ ls *.heapprofile
Heap.20190409.202950.15293.0.001.heapprofile
Stability: 1 - Experimental
Starts the V8 heap profiler on start up, and writes the heap profile to disk before exit.
If --heap-prof-dir
is not specified, the generated profile is placed
in the current working directory.
If --heap-prof-name
is not specified, the generated profile is
named Heap.${yyyymmdd}.${hhmmss}.${pid}.${tid}.${seq}.heapprofile
.
$ node --heap-prof index.js
$ ls *.heapprofile
Heap.20190409.202950.15293.0.001.heapprofile
