浏览指标和资源类型

本页介绍如何使用 Monitoring API 执行以下操作：

  • 获取自定义指标类型的列表或描述。
  • 获取内置指标类型的列表或描述，这可以帮助您设计自定义指标。文档中也提供了该列表，具体请参阅指标列表。
  • 获取可用受监控资源类型的列表或描述，您可以用其来标记自定义指标的时间序列数据。文档中也提供了该列表，具体请参阅受监控的资源列表。

如需了解这些概念，请参阅指标、时间序列和资源。

本页面介绍 metricDescriptors.list 和 get 方法以及 monitoredResourceDescriptors.list 和 get 方法。使用这些方法的方式有若干种：

  • 为了在不编写任何代码的情况下运行这些方法，本页面上的协议标签页中的示例使用基于表单的 API Explorer。（如需详细了解此工具，请参阅 API Explorer。）

  • 要了解如何从所选编程语言使用这些方法，请参阅本页面上的可运行代码示例。

工作区不是必需的

除非要使用自定义指标，否则您可以在 metricDescriptors.list 和 get 调用中使用任何现有项目，即使项目不在工作区中也无妨。如果要使用自定义指标，则必须指定定义了这些自定义指标的项目。

您还可以在 monitoredResourceDescriptors.list 和 get 方法中使用任何现有项目。

列出指标描述符

指标描述符是对内置指标和自定义指标进行定义的架构。通过浏览可用的指标描述符，您可以找到您想要了解的指标的详细信息。

目前有 900 多个内置指标；如需参考，请参阅完整的指标列表。

如需详细了解指标类型的命名方式，请参阅命名规则。

示例：列出指标类型

要获取当前的指标类型列表，请使用 metricDescriptors.list 方法。可使用过滤条件来减少返回的指标类型数量。请参阅指标类型，帮助确定要搜索的指标类型名称。

协议

以下是用于返回 Compute Engine 指标的 metricDescriptors.list 示例参数：

  • name：projects/[PROJECT_ID]
  • filter：metric.type = starts_with("compute.googleapis.com")
  • fields：metricDescriptors.type,metricDescriptors.displayName

试试看！

将 [PROJECT_ID] 更改为有效的 ID，然后点击执行按钮。

以下示例输出显示了与过滤条件相匹配的许多 Compute Engine 指标中的三个：

"metricDescriptors": [
  {
   "displayName": "Dropped bytes",
   "type": "compute.googleapis.com/firewall/dropped_bytes_count"
  },
  {
   "displayName": "Dropped packets",
   "type": "compute.googleapis.com/firewall/dropped_packets_count"
  },
  {
   "displayName": "Reserved cores.",
   "type": "compute.googleapis.com/instance/cpu/reserved_cores"
  },
  ...
]

这里的 type 值标识指标描述符，例如 compute.googleapis.com/firewall/dropped_packets_count。此值有时也称为“指标类型^”或“指标类型名称”。

C#

public static object ListMetrics(string projectId)

    MetricServiceClient client = MetricServiceClient.Create();

    foreach (MetricDescriptor metric in metrics)
    {
        Console.WriteLine($"{metric.Name}: {metric.DisplayName}");
    }
    return 0;

示例：获取指标描述符

要获取有关指标类型的更多详细信息，请使用 metricDescriptors.get 方法检索完整的指标描述符。

要检索特定的指标描述符，您需要描述符的全名。此值由两个组件构成：

  • 由 projects/[PROJECT_ID]/metricDescriptors 组成的前缀。
  • 标识指标描述符的 type 值，例如 compute.googleapis.com/firewall/dropped_packets_count。如需详细了解 type 值，请参阅《示例：列出指标类型》中的协议标签页。

示例：projects/[PROJECT_ID]/metricDescriptors/compute.googleapis.com/firewall/dropped_packets_count。

协议

要获取 Compute Engine 的 /firewall/dropped_packets_count 指标的详细信息，请对 metricDescriptors.get 使用以下参数：

  • name： projects/[PROJECT_ID]/metricDescriptors/compute.googleapis.com/firewall/dropped_packets_count

试试看！

将 [PROJECT_ID] 更改为有效的 ID，然后点击执行按钮。

以下示例响应显示了该指标的描述符：

列出受监控的资源

受监控的资源是可以受监控的云端实体。通过浏览现有的受监控资源类型，您可以找到具有指标的实体种类。

目前大约有 100 种不同的受监控资源描述符；请参阅受监控的资源列表，查看完整集合。

如需了解指标描述符和受监控的资源，请参阅指标、时间序列和资源。

您可以在 monitoredResourceDescriptors.list 和 get 调用中使用任何现有项目，即使项目不在工作区中也无妨。

示例：列出资源类型

要从 Monitoring API 获取受监控的资源类型的当前列表，请使用 monitoredResourceDescriptors.list 方法并提供项目 ID。

协议

要获取受监控的资源类型的当前列表，请将 monitoredResourceDescriptors.list 与以下示例参数结合使用：

  • name：projects/[PROJECT_ID]
  • fields：resourceDescriptors.type

试试看！

将 [PROJECT_ID] 更改为有效的 ID，然后点击执行按钮。

查找资源

受监控资源对象包含在时间序列数据中。您通常可以猜到哪些指标包含特定类型的受监控资源。例如，如果您想查看 gce_instance 受监控资源，请查看来自类似 compute.googleapils.com/instance/cpu/utilization 的指标的时间序列数据。在确定了可能的指标时间序列后，请参阅读取指标数据。
