如何对性能计数器类别进行版本控制？

发布于 2024-08-08 08:55:34 字数 534 浏览 2 评论 0原文

我有一个性能计数器类别。此类别中的计数器可能会在我的下一个版本中发生变化，因此当程序启动时，我想检查该类别是否存在以及它是否是正确的版本 - 如果不存在，则创建新类别。我可以通过在帮助字符串中存储 GUID 来做到这一点，但这显然很臭。是否可以使用 .NET API 更干净地完成此操作？

现有的臭版本...

if (PerformanceCounterCategory.Exists(CATEGORY_NAME))
{
    PerformanceCounterCategory c = new PerformanceCounterCategory(CATEGORY_NAME);
    if (c.CategoryHelp != CATEGORY_VERSION)
    {
        PerformanceCounterCategory.Delete(CATEGORY_NAME);
    }
}

if (!PerformanceCounterCategory.Exists(CATEGORY_NAME))
{
      // Create category
}

I have a performance counter category. The counters in this category may change for my next release so when the program starts, I want to check if the category exists and it is the correct version - if not, create the new category. I can do this by storing a GUID in the help string but this is obviously smelly. Is it possible to do this more cleanly with the .NET API?

Existing smelly version...

if (PerformanceCounterCategory.Exists(CATEGORY_NAME))
{
    PerformanceCounterCategory c = new PerformanceCounterCategory(CATEGORY_NAME);
    if (c.CategoryHelp != CATEGORY_VERSION)
    {
        PerformanceCounterCategory.Delete(CATEGORY_NAME);
    }
}

if (!PerformanceCounterCategory.Exists(CATEGORY_NAME))
{
      // Create category
}

在我们的系统中，每次应用程序启动时，我们都会检查现有类别。如果未找到，我们将创建该类别。如果存在，我们会将现有类别与我们期望的类别进行比较，如果存在缺失值，则重新创建它（删除、创建）。

var missing = counters
.Where(counter => !PerformanceCounterCategory.CounterExists(counter.Name, CategoryName))
.Count();

if (missing > 0)
{
    PerformanceCounterCategory.Delete(CategoryName);

    PerformanceCounterCategory.Create(
        CategoryName,
        CategoryHelp,
        PerformanceCounterCategoryType.MultiInstance,
        new CounterCreationDataCollection(counters.Select(x => (CounterCreationData)x).ToArray()));
}

In our system, each time the application starts we do a check for the existing category. If it isn't found, we create the category. If it exists, we compare the existing category to what we expect and recreate it (delete, create) if there are missing values.

var missing = counters
.Where(counter => !PerformanceCounterCategory.CounterExists(counter.Name, CategoryName))
.Count();

if (missing > 0)
{
    PerformanceCounterCategory.Delete(CategoryName);

    PerformanceCounterCategory.Create(
        CategoryName,
        CategoryHelp,
        PerformanceCounterCategoryType.MultiInstance,
        new CounterCreationDataCollection(counters.Select(x => (CounterCreationData)x).ToArray()));
}
