获取cpu负载时 使用pdhaddenglishcounter 返回-1073738824  C000 0BB8  

PDH_CSTATUS_NO_OBJECT 

 

auto state = PdhOpenQuery(NULL, NULL, &cpuQuery);
            if (state != ERROR_SUCCESS) {
                DLOG(ERROR) << "PdhOpenQuery Failed:" << state << std::endl;
                return 0;
            }
            state = PdhAddCounter(cpuQuery, "\\Processor(_Total)\\% Processor Time", NULL, &cpuTotal);
            if (state != ERROR_SUCCESS)
            {
                DLOG(ERROR) << "PdhAddEnglishCounter Failed" << PdhAddEnglishCounter(cpuQuery, "\\Processor(_Total)\\% Processor Time", NULL, &cpuTotal) << std::endl;
                return 0;
            }
