Provide efficient parsing and convertion for gperftools CPU/MEM Profile.
incldudes：
- profile IO
- local generation of symbolized profile it can be submmited to remote server for later processing, such as flamegraph generation.
- others more utility comming soon.
GNU binutils lib, if not exists on current os, install it using yum or other package tools according to your os:
yum install binutils-devel.x86_64#include "profiling/cpu_profile.h"
int GenerateSymbolizedProfile(const std::string &file, std::string *output) {
pprofcpp::CPUProfile profile{file};
if (auto st = profile.Parse(); st != pprofcpp::ReaderRetCode::kOK) {
return static_cast<int>(st);
}
pprofcpp::BfdSymbolLocator locator;
RawProfileMeta meta;
meta.program_path = "testbin";
if (auto st = profile.GenerateRawProfile(meta, &locator, output); st != pprofcpp::CPUProfileRetCode::kOK) {
return static_cast<int>(st);
}
return 0;
