Alpha 版或抢先体验发布阶段的指标类型可能不会显示在公开指标列表中。要获取这些指标类型的相关信息，请从已获准使用受限指标类型的 Google Cloud项目中明确检索指标描述符集。如果您有权使用受限指标类型，则可以使用 Monitoring API 中的 metricDescriptors.list 方法检索指标描述符。如需了解详情，请参阅列出指标描述符。
其他信息：元数据
每个指标类型的说明都包含有关该指标的信息，称为元数据。元数据包括以下内容：
采样周期：对于定期写入的指标，这是连续数据点之间的时间间隔，不包括错误导致的数据丢失。该时间段（如有）显示在说明文字的末尾，其形式为“每 x 秒采样一次”。
延迟时间：保证早于该值的数据点都可以读取，不包括错误导致的数据丢失。延迟时间不包括等待下一个采样周期的时间。延迟时间（如有）显示在说明文字的末尾，其形式为“采样后，数据在最长 y 秒的时间内不会显示”。

This document provides\nlinks to reference lists for each of these groups.\n\nMetrics from Google Cloud services include:\n\n- [Google Cloud metrics](/monitoring/api/metrics_gcp), for Google Cloud services such as Compute Engine and BigQuery.\n- [Google Distributed Cloud metrics](/monitoring/api/metrics_anthos), for Google Distributed Cloud software only.\n- [Istio metrics](/monitoring/api/metrics_istio), for Istio on Google Kubernetes Engine.\n- [Kubernetes metrics](/monitoring/api/metrics_kubernetes), for Google Kubernetes Engine (GKE).\n\nMetrics from agents, open-source, and third-party applications include:\n\n\u003cbr /\u003e\n\n- Metrics for the legacy Cloud Monitoring and Cloud Logging agents,\n as well as the Ops Agent. With the exception of metrics from\n third-party applications, the Ops Agent and the legacy agents share\n many groups of metrics.\n\n - [Ops Agent metrics](/monitoring/api/metrics_opsagent), for VM instances\n running the Ops Agent.\n\n - [Legacy Monitoring and Logging agent\n metrics](/monitoring/api/metrics_agent), for VM instances running the\n legacy Monitoring and Logging agents.\n\n- [Knative metrics](/monitoring/api/metrics_knative), for Knative\n components.\n\n- [External metrics](/monitoring/api/metrics_other), for\n open-source and third-party applications.\n\nAbout the lists\n---------------\n\nThe tables in the metric-type lists are regenerated frequently and time-stamped.\nThe information listed for each metric type comes from\nthe Monitoring API [`MetricDescriptor`](/monitoring/api/ref_v3/rest/v3/projects.metricDescriptors#MetricDescriptor)\nobject for each metric type. For more information about how metric\ntypes are described, see\n[Metrics, time series, and resources](/monitoring/api/v3/metrics).\n\nLaunch stages\n-------------\n\nEach metric type has a launch stage that indicates its maturity. If specified,\nthe launch stage appears as a colored superscript after the metric type:\n^GA^,\n^BETA^,\n^ALPHA^,\n^EARLY_ACCESS^, or\n^DEPRECATED^.\nIf no superscript appears, then the launch stage is unspecified.\nFor more information, see [Product launch stages](/products#product-launch-stages).\n\nMetric types in the Alpha or Early Access launch stages might not appear in\nthe public lists of metrics. To get information about those metric types,\nexplicitly retrieve the set of metric descriptors from a Google Cloud\nproject that has been given permission to use the restricted metric types.\nIf you have permission to use restricted metric types, you can retrieve\nthe metric descriptors by using the\n[`metricDescriptors.list`](/monitoring/api/ref_v3/rest/v3/projects.metricDescriptors/list) method in the\nMonitoring API. For more information, see\n[List metric descriptors](/monitoring/custom-metrics/browsing-metrics#list-metric-descriptors).\n\nAdditional information: metadata\n--------------------------------\n\nThe description for each metric type includes information called *metadata*\nabout the metric. The metadata includes the following:\n\n- **Sample Period** : For metrics that are written periodically, this is the\n time interval between consecutive data points, excluding data loss due to\n errors. The period, if available, appears at the end of the description\n text in a sentence of the form *\"Sampled every* x\n *seconds.\"*\n\n- **Latency** : Data points older than this value are guaranteed to be\n available to be read, excluding data loss due to errors. The delay does not\n include any time spent waiting until the next sampling period. The delay, if\n available, appears at the end of the description text in a sentence\n of the form *\"After sampling, data is not visible for up to* y\n *seconds.\"*\n\n- **Resource hierarchy levels**: Most metrics are collected only for\n projects, but some metrics are also collected at the organization and folder\n levels. If a level is not specified in the metadata, then the metric is\n written at the project level.\n\nPricing\n-------\n\nIn general, Cloud Monitoring system metrics are free, and metrics\nfrom external systems, agents, or applications are not. Billable metrics are\nbilled by either the number of bytes or the number of samples ingested.\n\nFor more information, see the Cloud Monitoring sections of the [Google Cloud Observability pricing](https://cloud.google.com/stackdriver/pricing) page.\n\nGetting started\n---------------\n\n- For an introduction to the concepts and terminology used in the Cloud Monitoring metric model, see [Metrics, time series, and resources](/monitoring/api/v3/metrics).\n- To create your own metrics, see [Create user-defined metrics with the API](/monitoring/custom-metrics), [User-defined agent metrics](/monitoring/agent/custom-metrics-agent), and [Logs-based metrics](/logging/docs/view/logs_based_metrics).\n- To quickly see graphs of metric data, use the Metrics Explorer.
