In my application, I am gathering data regarding the performance of system, where I need to find
- % Free Space
- % Disk Time
- % Disk Read Time
- % Disk Write Time
- % Idle Time
- % Usage
- % Usage Peak
using below function;
private void CollectnPopulatePerfCounters() { try { foreach (var pc in System.Diagnostics.PerformanceCounterCategory.GetCategories()) { if (pc.CategoryName == "LogicalDisk" || pc.CategoryName == "Paging File" || pc.CategoryName == "ProcessorPerformance") { try { foreach (var insta in pc.GetInstanceNames()) { try { foreach (PerformanceCounter cntr in pc.GetCounters(insta)) { using (System.IO.StreamWriter sw = new System.IO.StreamWriter("C:\\amit.txt", true)) { sw.WriteLine("--------------------------------------------------------------------"); sw.WriteLine("Category Name : " + pc.CategoryName); sw.WriteLine("Counter Name : " + cntr.CounterName); sw.WriteLine("Explain Text : " + cntr.CounterHelp); sw.WriteLine("Instance Name: " + cntr.InstanceName); sw.WriteLine("Value : " + Convert.ToString(cntr.RawValue)); //TODO: sw.WriteLine("Counter Type : " + cntr.CounterType); sw.WriteLine("--------------------------------------------------------------------"); } } } catch (Exception) { } } } catch (Exception) { } } } } catch (Exception) { } } When the code is executed the data is generated. While observing I found that the value against the above mentioned list [i.e. % free space, % disk time etc.] is not in correct form.
On my machine the value for
- % Disk Read Time = 44553438000 for C Drive
- % Usage Peak = 48386 for \??\C:\pagefile.sys
actually the value should be in the percent form [i.e within the range of 0 to 100 %]
Is there any way to get the exact value for all these except [% free Space for which I have calculated].
Or
Does anyone know how to calculate for rest of all headers.
