cpu profiler 是可以正常使用的，heap profiler显示如下

[20230227.150700.heap] Using local file bin/asr_service. Argument "MSWin32" isn't numeric in numeric eq (==) at ./rpc_data/profiling/pprof.pl line 4898.

我是将内置服务的代码插入到.a链接的，发现在本地跑heap和contention profiler可以正常使用，但是在服务器上跑就会出现上面的问题

服务器上的版本是链接了tcmalloc吗

@lorinlee 本地和服务器跑的是同一套代码，都链接了libtcmalloc_and_profiler.so.4，然后我发现还另外链接了libjemalloc.so.2这个库，是因为这个的原因吗（但是本地也链接了这个，却能看heap和contention）

@17336 可以去掉jemalloc的链接尝试下看看

去掉了也还是不行

@17336 可以去掉jemalloc的链接尝试下看看

可以问下出现Argument "MSWin32" isn't numeric这个的原因嘛，感觉出在这个地方挺奇怪的

17336 commented 1 year ago

@17336 可以去掉jemalloc的链接尝试下看看

@lorinlee 请问目前只有cpu profiler能用jemalloc，heap不能用对吧？因为tcmalloc有瓶颈，线上服务只考虑用jemalloc

17336 commented 1 year ago

heap profiler有可能支持jemalloc吗

lorinlee commented 1 year ago

@17336 jemalloc可以用jemalloc自带的jeprof的
