For 4 cores, PerformanceCounter("Process", "% Processor Time", Process.GetCurrentProcess().ProcessName) can return up to 400 meaning that process is using 100% of each CPU. , so if 2 are 10% and 6 at 5% the the counter shows around 6%. There is NO counter in PerfMon that matches what you see in Task Manager on the Processes tab in CPU column. To test I used the benchmarking tool in 7zip. Application Insight Performance Counter in Azure, performance counter value of _total is less then single instance's value, Performance counters for Worker Role in Windows Azure. Taskmgr utilizes a NtQuerySystemInformation call for this value. Processor(_Total)\% User Time = 51.853 The ranks and associated badges have gone "Star Fleet". Making statements based on opinion; back them up with references or personal experience. Is there a puzzle that is only solvable by assuming there is a unique solution? Any way to watch Netflix on an 1stGen iPad Air (MD788LL/A)? On a healthy 1Gbit network, a 100MB file should copy in about 3 to 5 seconds. In this scenario, consider reducing the number of virtual processors allocated to Hyper-V virtual machines on the host operating system.Hyper-V provides hypervisor performance objects to monitor the performance of both logical and virtual processors. Use the following performance monitor counters to measure network utilization on the Hyper-V host operating system: If a network adapter on the Hyper-V root partition is busy as indicated by the performance monitor counters mentioned above, then consider using the "\Hyper-V Virtual Network Adapter(*)\Bytes/sec" performance monitor counter to identify which virtual network adapters are consuming the most network utilization. We’re sorry. Virtual processors are what the virtual machines actually use, and all execution in the root and child partitions occurs in virtual processors. Maybe this question is simple, but I need a confirmation. @Legend My cursory testing shows it's the sum of the processor usage across each processor. Real process CPU would be = 5.17375 / 8 cores = 64.662% ~ Processor(_Total)\% So for instance, if CPU1 is 30%, CPU2 is 30%, CPU3 is 30%, CPU4 is 30%, will Perfmon counter show it as 120%? On local area networks, expect to receive less than 1ms response times. Thanks a lot! Processor(_Total)\% Privileged Time = 15.369 This Azure counter is simply a recording of the Windows Performance Counter, The simplest measure of a system's The theoretical Max for this counter is (# of processors * 100), A single CPU and we are looking a single point of time, (process\% processor time\your application) = 80%, You application is using 80% of the (processor\% user time) which is (8*.8)=6.4% of the CPU. If VPTR is high and LPTR is low, then consider allocating additional processors to virtual machines if there are available logical processors and if additional processors are supported by the guest operating system. If you have multiple processors they you will need to divide the (process\% processor time\your application) by the number of processors to determine what will be charged to % user time. Although these two counters are named the same, they are calculated quite differently: The % Processor Time for the _Total instance under the Processor object shows an AVERAGE of the processor used across all cpus (we have 8.) Why this isn't made clear anywhere is unfortunate, as is having to rely on a cursory test. Let's say I'm interested in the "black line " user process in this graph below, as his process is spiking quite high compared to all the other users: Using this as an example, I see that this worker process user has an AVERAGE % PROCESSOR TIME of 23.264 , and has spiked as high as 103.124, So - what exactly does this 23.264 number mean to me? 计算机中所有处理器的处理器活动的度量。 "N[{y8_0此计数器采样间隔期间的所有处理器平均非空闲时间的总和,并用处理器数目除以该和。51Testing软件测试网 In the case of processor utilization, the hypervisor schedules the guest processor time to physical processor in the form of threads. Does the preparation of Chicken liver mousse require force-feeding of chickens? Process Explorer also matches the counter from Task Manager, which Perfmon Process: % Processor Time vs. Note that if you have a multiprocessor machine, Processor(_Total)\% Processor Time actually measures the average processor utilization of your machine (i.e.
