perfmon

问题 this is driving me crazy. I have 2 testing machine, one XP, and one Vista. I am running the same commands on both. These commands include creating a logman counter ( like a perfmon with command prompt), starting these counters, then stopping them, and then deleting them. The problem is this: On XP they work perfectly, I am getting all the statistics, and it works always. On Vista, they work on the first time, but then I always get the error back, "The RPC server is unavailable." This happens

问题 I am trying to use Jmeter perfmon plugin to monitor cpu and memory utilisation of server. Server is hosted on linux machine and is running apache and postgresql. I am running serveragent in linux server and added cpu and memory parameters in Jmeter perfmon metrics collector. Now when I run my Jmeter tests then both apache and postgrelsql are used.I can see some data coming in performance collector. 1)How can I find cpu utilization of apachae and progresql when test are run? 2) I can see

问题 I have a C++ application (under Win32) for which I need to provide performance counter information. I'm using Perflib v2, so have created a manifest which is processed by CTRPP. My provider then calls PerfAutoInitialize and PerfCreateInstance with no errors. When I go to add the counter in Perfmon, my application crashes. Tracing through the disassembly shows the code in the perflib worker thread calling the internal function (pcwum.dll) PerfpAddOrRemoveCounter. This calls on to

问题 Years ago I wrote some code to "publish" data for perfmon to consume. Using those counters is pretty well documented, but I found it challenging to find (at the time) good documentation and sample code to publish the data for perfmon. Does anyone know where I can get this documentation? I also seem to recall some class wrappers, but I may be mistaken. EDIT: I did find this, and I will keep looking for "custom application performance counters". 回答1: You're bringing back old memories! From 1998

问题 I have an app that collects Perfmon counter values through the API exposed in winreg.h - in order to collect Perfmon counter values I must make a call to RegQueryValueExW passing in the id of the Perfmon counter I'm interested in, and in order to obtain that ID I need to query the registry for the list of Perfmon counter names and go through looking for the one I'm interested in C++ isn't my language of choice, so the following is a shaky example, probably with lots of syntax errors but you

问题 I have this simple code: public void CreateCounters() { if (PerformanceCounterCategory.Exists(_categoryName)) { PerformanceCounterCategory.Delete(_categoryName); } // create logic… } works on my machine. I run it on my server, get the following stack trace: System has detected a fatal error. EXITING... NativeErrorCode: 1010 ErrorCode: -2147467259 Message: The configuration registry key is invalid TargetSite: Void RegisterFiles(System.String, Boolean) HelpLink: Source: System Stack Trace: at

问题 I need to prevent the processor from entering an idle state (non C0 C state). Admittedly I do not know much about processor C and P states so bear with me. We use a camera from a third party vendor which occasionally delivers corrupted frames. The vendor has determined that when the CPU enters an idle state it interferes with the transmission of the frame over the firewire. To confirm this I used the following code on a Windows 7 PC and indeed, disabling the idle states resolved the issue. /

问题 When I try to run this code: var categories = System.Diagnostics.PerformanceCounterCategory.GetCategories(); I get an ArgumentException exception.

问题 I'm trying to create a data collector set using Perfmon. When I right click 'New -> Data Collector Set' in the User Defined folder, I see the wizard dialog appear. However, the 'Next' and 'Finish' buttons are disabled. All I can do is click on Cancel. Any ideas? 回答1: Found the answer to this while googling a problem with the disk defragger. The recommendation I found was to (backup first!) remove the registry key: HKLM\Software\Microsoft\RPC\Internet I exported the key for a backup; deleted
