performancecounter

I am trying to get the % of total CPU usage to a label1.Caption I've searched and found these: didn't work - http://www.vbforums.com/showthread.php?345723-DELPHI-Get-CPU-Usage not what I need - http://delphi.cjcsoft.net/viewthread.php?tid=42837 also found bunch of solutions regarding calculating the Usage per process but that is not what i am looking for , i just want the total CPU usage like this widget : this is what i am working on : I believe there is a simple way like when we get RAM usage. GlobalMemoryStatus(RamStats); Label1.Caption := Format('RAM: %d %%', [RamStats.dwMemoryLoad]); I

I need to attach a unique identifier to objects at runtime. The identifier must be unique for the duration of the application. I plan to do this my having a private member variable in the base class of my object model. This variable will be set at object initialization and the value will remain constant for the life of the object. No other object can have the same identifier for the duration of the application. I can, of course, use a System.Guid , but that costs a 128 bits of storage for each object and I would like to consume fewer resources. I tried using an Int32 and initializing it with

I would like to display some memory statistics (working set, GCs etc.) on a web page using the .NET/Process performance counters. Unfortunately, if there are multiple application pools on that server, they are differentiated using an index (#1, #2 etc.) but I don't know how to match a process ID (which I have) to that #xx index. Is there a programmatic way (from an ASP.NET web page)? The first hit on Google: Multiple CLR performance counters appear that have names that resemble "W3wp#1" When multiple ASP.NET worker processes are running, Common Language Runtime (CLR) performance counters will

I have a custom counter category, to which I need to add a new counter, without deleting or resetting any existing counters. How can I do this? I tried using CounterExists(), but even after I create the counter, how can I associate it to a CounterCreationDataCollection item and associate it to my existing counter category? Levitikon The best way to do this I found, especially since there doesn't seem to be much info on this topic, is to preserve the existing raw values and then re-apply them after the category is deleted and re-created. /// <summary> /// When deleting the Category, need to

I'm trying to move the verification & creation of my performance counter groups, and the counters themselves, out of my web service and into a powershell script that's run during deployment. Can this be done? Or am I stuck using a simple app to build the groups & counters? Thanks much :) Figured this out a while ago, but never posted. Here's my solution: //save out the type name for sanity's sake $ccdTypeName = 'System.Diagnostics.CounterCreationData' $CounterCollection = New-Object System.Diagnostics.CounterCreationDataCollection //create as many counters as we'd like, and add them to the

I want to display CPU usage for my multithread application (working over multicore processor). I want to receive numbers close to Task manager's. But I got numbers more than 100%. Even more than 500%. Yes, I know, than counter "% Processor Time" for category "Process" I need to divide into Environment.ProcessorCount or "NumberOfLogicalProcessors" (same for my configuration). And 500% is a result after this operation. I tested this example on different computers with different hardware (i7, i5, Core2) and software configurations (Windows 7 SP1 with all updates, Windows 2008 R2 SP1 with all
