Using hdeem_cxx

 #include "hdeem_cxx.hpp"
int main(int argc, char** argv) {

hdeem::connection hdeem;
/**
 * Be sure to init HDEEM before any other code, especially before you 
 * fork processes, threads, or allocate a huge amount of memory. 
 **/

//some other init code

hdeem.start();

// something to measure

hdeem.stop();

auto stats = hdeem.get_stats();
std::cout << "Blade energy: " << stats.energy(hdeem::sensor_id::blade(0)) << "\n";
std::cout << "Blade power: " << stats.average(hdeem::sensor_id::blade(0)) << "\n";
}

Build

You need to link freeipmi and rt additionaly to the originonal hdeem module.

g++ test.cpp -std=c++14 -o test -I./hdeem_cxx/include/ -lhdeem -lfreeipmi -lrt
