パフォーマンスカウンターのカテゴリー名？ （C＃）
別のプロセスを起動し、起動されたプロセスのプロセッサ使用率をチェックするC＃アプリケーションにパフォーマンスカウンターをプログラムしようとしています。私が理解しているように、パフォーマンスカウンタークラスでは、カテゴリ名、カウンター名、およびプロセス名を割り当てる必要があります。プロセス名は簡単に取得できますが、インターネット上に、割り当て可能なすべてのカテゴリ名とカウンタ名が記載されたリストがありますか？このようなものをMSDNで調べてみましたが、何も見つかりませんでした。
すべての助けをありがとう！
プロセスのどの側面を監視できるかを知りたいと思います。プロセスパフォーマンスカウンターのリストが利用可能です ここ それでも、 GetCategories staticメソッドを使用して、マシン内のすべてのカテゴリを一覧表示できます。または、より具体的に、次のPerformanceCategoryを作成することもできます。 「プロセス」カテゴリを選択し、 GetCounters を使用して、使用可能なすべてのカウンタのリストを取得します。お役に立てれば。
CriGoTが上に書いたことを示すメソッド、小さなショートカットを作成しました。
private static void GetAllCounters(string categoryFilter)
{
var categories = PerformanceCounterCategory.GetCategories();
foreach (var cat in categories)
{
if (categoryFilter != null && categoryFilter.Length > 0)
{
if (!cat.CategoryName.Contains(categoryFilter)) continue;
}
Console.WriteLine("Category {0}", cat.CategoryName);
try
{
var instances = cat.GetInstanceNames();
if (instances != null && instances.Length > 0)
{
foreach (var instance in instances)
{
//if (cat.CounterExists(instance))
//{
foreach (var counter in cat.GetCounters(instance))
{
Console.WriteLine("\tCounter Name {0} [{1}]", counter.CounterName, instance);
}
//}
}
}
else
{
foreach (var counter in cat.GetCounters())
{
Console.WriteLine("\tCounter Name {0}", counter.CounterName);
}
}
}
catch (Exception)
{
// NO COUNTERS
}
}
Console.ReadLine();
}
この助けを願っています。
必要なカウンターをすばやく参照して見つけたい場合は、|Categories|Instances|Counters|の3つのリストボックスとタイマーで更新されるカウンター値を表示するクイックフォームをご覧ください。フィルター付き。

好きなように割り当てることができます。パフォーマンスモニターには、選択したカテゴリと、特定のニーズに合わせて選択したカウンター名が表示されます。
CounterCreationDataCollection ccdc = new CounterCreationDataCollection();
ccdc.Add(new CounterCreationData("Counter Title", "Counter Description", PerformanceCounterType.NumberOfItems32));
PerformanceCounterCategory.Create("My Counter Category", "Category Description", PerformanceCounterCategoryType.Unknown, ccdc);
