我有一个自定义的计数器类别，而我需要添加一个新的计数器，而不会删除或重置任何现有的计数器。我怎样才能做到这一点？

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?

我试图用CounterExists（），但即使在我创作的柜台，我怎么能它关联到CounterCreationDataCollection项，并将其关联到我现有的反类？

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?

推荐答案

要做到这一点，最好的方法，我发现，尤其是因为似乎没有要对这个话题很多信息，是preserve现有的原料值，然后后该类别被删除并重新创建重新申请他们。

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 preserve the existing counter values /// </summary> static Dictionary<string, long> GetPreservedValues(string category, XmlNodeList nodes) { Dictionary<string, long> preservedValues = new Dictionary<string, long>(); foreach (XmlNode counterNode in nodes) { string counterName = counterNode.Attributes["name"].Value; if (PerformanceCounterCategory.CounterExists(counterName, category)) { PerformanceCounter performanceCounter = new PerformanceCounter(category, counterName, false); preservedValues.Add(counterName, performanceCounter.RawValue); Console.WriteLine("Preserving {0} with a RawValue of {1}", counterName, performanceCounter.RawValue); } else { Console.WriteLine("Unable to preserve {0} because it doesn't exist", counterName); } } return preservedValues; } /// <summary> /// Restore preserved values after the category has been re-created /// </summary> static void SetPreservedValues(string category, Dictionary<string, long> preservedValues) { foreach (KeyValuePair<string, long> preservedValue in preservedValues) { PerformanceCounter performanceCounter = new PerformanceCounter(category, preservedValue.Key, false); performanceCounter.RawValue = preservedValue.Value; Console.WriteLine("Restoring {0} with a RawValue of {1}", preservedValue.Key, performanceCounter.RawValue); } }
