cpu-usage

问题 I don't want the list of all process, just a total percentage like you would see in windows taskmanager. I will be using this information via coldfusion, but i am having all kinds of problems just trying to find a total number of current cpu usage. I don't care if it comes from wmi or t-sql, i just want a total number for which i will be using to populate a gauge chart that via ajax will be showing my current cpu usage percentage... Thank You... 回答1: You can use the Win32_PerfRawData_PerfOS

问题 I am using DebugDiag Analysis tool in the server to generate report for the dump file which is 1.74 GB and it's running for more than a day and could not generate report. I also tried running the tool in separate computer (local) https://www.iis.net/learn/troubleshoot/performance-issues/troubleshooting-high-cpu-in-an-iis-7x-application-pool It stops on "Preloading symbol files (this may take a while)" 来源： https://stackoverflow.com/questions/56782704/debugdiag-analysis-is-taking-too-long-to

问题 Closed. This question needs debugging details. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed last month . Improve this question I translated a Java program into C++, and I was getting very slow performance from C++ as compared to Java. Looking at the activity monitor, I saw that the Java program, which I ran first, was using over 90% of the CPU, while the C++ program was using around 30%. It appears that

问题 I want to restrict cpu usage of users to only 25% . For this i am using cgroups. Here is the guide that I am following : http://kaivanov.blogspot.in/2012/07/setting-up-linux-cgroups-control-groups.html This guide work with one core cpu machine, but when i am using with the 4 core cpu machine this configuraion doe not work. Here is my configuration: # Configuration file generated by cgsnapshot mount { cpu = /cgroup/cpu; } group test1 { cpu { cpu.rt_period_us="1000000"; cpu.rt_runtime_us="0";

问题 I ran the following Java code on a Linux server: while (true) { int a = 1+2; } It caused one CPU core to reach 100% usage. I'm confused about this, because I learnt that CPUs deal with tasks by time splitting, meaning that the CPU will do one task in one time slot (CPU time range scheduler). If there are 10 time slots, the while true task should have at most use 10% CPU usage, because the other 90% would be assigned to other tasks. So why is it 100%? 回答1: If your CPU usage is not at 100%,

问题 This question already has answers here : Get Memory Usage in Android (6 answers) Closed last month . I want to get the average CPU usage in Android per 100ms or 500ms. I have tried to use top and dumpsys cpuinfo , but neither of them tell me the average usage or the timestamp. So how can I get the average usage? I notice that there is some CPU usage information in /proc/stat , can I calculate average CPU usage using /proc/stat ? 回答1: I've tested the solution by Krypton, and got wrong numbers

问题 I am in the 'forbidden' scenario of having SBA server and client in one app (so there is only one app registered for any SBA server instance, which is itself). For various reasons I can't change that. I see a huge cpu usage when being on the insights>details page. No clue why, the only thing I can think of is I have a "lot of" caches (like 40). Any guesses on that cpu usage? The second thing is: I am unable to find a config setting how often the graphs on the detail page get updated. Is there

问题 [My Attempts] Already went through How to get the CPU Usage in C#? But "_Total" Instance of Processor would give me total consumption of CPU as opposed to specifc application or 'process' In a C# Program, I am trying to get the CPU usage percentage of the application but it always shows 100 What exactly is CPU Time in task manager? , explains it but does not say how to retrive this value.
