List metric and resource types

This document explains how to use the Cloud Monitoring API to get lists or descriptions of the following:

User-defined metric types defined in your project.
Third-party metric types with time-series data in your project. Metrics generated by Bindplane are examples of third-party metrics. Bindplane metrics have a prefix of workload.googleapis.com/ 3rd-party-app-name / . For a full list of supported third-party application metrics, see the Bindplane Sources documentation .
Built-in metric types provided by Google Cloud. These metric types can help you design your user-defined metrics. You can also find information about these metrics in the documentation; see Metrics list .
Monitored resource types available to your project. You can also find information about these resources in the documentation; see Monitored resource list .

There are several ways to use the API methods that this document describes:

To run the methods without writing any code, the examples in the Protocoltabs on this page use the forms-based APIs Explorer. (See APIs Explorer for more information about this tool.)
To learn how to use the methods from selected programming languages, see the runnable code samples on this page.

Before you begin

For an introduction to metrics and monitored resources, see Metrics, time series, and resources .

List metric descriptors

Metric descriptors are the schemas that define metrics. To find details about the metrics you're interested in, browse the available metric descriptors:

Built-in metrics: You can issue API requests to any existing project, or you can use Metrics lists documentation.
User-defined and external metrics: You must issue the API request to a project where the user-defined metric is defined or where time-series data for the metric exists.

For more information on how metric types are named, see Naming conventions .

List metric types

To get a current list of metric descriptors, use the metricDescriptors.list method. To narrow the set of metric types that are returned, use a filter. For help deciding which metric types to search for, see Value types and metric kinds .

Protocol

Open the metricDescriptors.list reference page.
In the pane labeled Try this method, enter the following:
- name: projects/ PROJECT_ID . Replace PROJECT_ID with the ID of your Google Cloud project.
- filter: metric.type = starts_with("compute.googleapis.com")
Click Execute.

The following sample response shows some of the retrieved metric descriptors:

"metricDescriptors": [
      {
        "name": "projects/ PROJECT_ID 
/metricDescriptors/compute.googleapis.com/firewall/dropped_bytes_count",
        "labels": [{...}],
         ...
         "description": "Count of incoming bytes dropped by the firewall.",
         "displayName": "Dropped bytes",
         "type": "compute.googleapis.com/firewall/dropped_bytes_count",
         ...
      },
      {
         "name": "projects/ PROJECT_ID 
/metricDescriptors/compute.googleapis.com/firewall/dropped_packets_count",
         "labels": [{...}],
         ...
         "description": "Count of incoming packets dropped by the firewall.",
         "displayName": "Dropped packets",
         "type": "compute.googleapis.com/firewall/dropped_packets_count",
      },
      ...
    ]

The type value in each descriptor identifies the metric descriptor, for example, compute.googleapis.com/firewall/dropped_packets_count . This value is sometimes also called the “metric type” or the “metric type name”.

Get metric descriptors

To get information about a single metric type, use the metricDescriptors.get method . This method returns a metric descriptor.

To retrieve a specific metric descriptor, you must provide the full name of the metric to the API. The full name is constructed from two components:

A prefix consisting of projects/ PROJECT_ID /metricDescriptors .
The type value that identifies the metric descriptor, for example, compute.googleapis.com/firewall/dropped_packets_count . See the Protocoltab in List metric types for more on the type value.

The following is an example of the full name of a metric:

 projects/ PROJECT_ID 
/metricDescriptors/compute.googleapis.com/firewall/dropped_packets_count

Protocol

To get the descriptor for the Compute Engine /firewall/dropped_packets_count metric, do the following:

Open the metricDescriptors.list reference page.
In the pane labeled Try this method, enter the following:
- name: projects/ PROJECT_ID /metricDescriptors/compute.googleapis.com/firewall/dropped_packets_count
  
  Replace PROJECT_ID with the ID of your Google Cloud project.
Click Execute.

The following sample response shows the metric's descriptor:

{
        "name": "projects/ PROJECT_ID 
/metricDescriptors/compute.googleapis.com/firewall/dropped_packets_count",
        "labels": [
          {
            "key": "instance_name",
            "description": "The name of the VM instance."
          }
        ],
        "metricKind": "DELTA",
        "valueType": "INT64",
        "unit": "1",
        "description": "Count of incoming packets dropped by the firewall.",
        "displayName": "Dropped packets",
        "type": "compute.googleapis.com/firewall/dropped_packets_count",

List monitored resources

Monitored resources are cloud entities that can be monitored. To find the kinds of entities that have metrics, browse the list of monitored resource types.

To get information about monitored resources, you can issue API requests to any existing project, or you can use the Monitored resource list documentation.

List resource types

To get a current list of monitored resource types from the Monitoring API, use the monitoredResourceDescriptors.list method and supply your project ID.

Protocol

Open the monitoredResourceDescriptors.list reference page.
In the pane labeled Try this method, enter the following:
- name: projects/ PROJECT_ID . Replace PROJECT_ID with the ID of your Google Cloud project.
Click Execute.

The following sample response shows some of the returned monitored resource types:

{
    "resourceDescriptors": [
    {
      "type": "aiplatform.googleapis.com/Endpoint",
      "displayName": "AI Platform Endpoint",
      "description": "A Cloud AI Platform API Endpoint where Models are deployed into it.",
      "labels": [{...}],
      "name": "projects/ PROJECT_ID 
/monitoredResourceDescriptors/aiplatform.googleapis.com/Endpoint",
    },
    {
      "type": "aiplatform.googleapis.com/Featurestore",
      "displayName": "AI Platform Feature Store",
      "description": "A Cloud AI Platform Feature Store.",
      "labels": [{...}],

If you have difficulty, see Troubleshooting API calls .

Getting resource descriptors

To get a specific monitored-resource descriptor, use the monitoredResourceDescriptors.get method.

To retrieve a specific monitored-resource descriptor, you must provide the full name of the descriptor to the API. The full name is constructed from two components:

A prefix consisting of projects/ PROJECT_ID /monitoredResourceDescriptors .
The type value that identifies the monitored-resource descriptor, for example, gce_instance . See the Protocoltab in List resource types for more on the type value.

The following is an example of the full name of a monitored resource:

 projects/ PROJECT_ID 
/monitoredResourceDescriptors/gce_instance

Protocol

To get the descriptor for the gce_instance resource type, do the following:

Open the monitoredResourceDescriptors.get reference page.
In the pane labeled Try this method, enter the following:
- name: projects/ PROJECT_ID /monitoredResourceDescriptors/gce_instance
  
  Replace PROJECT_ID with the ID of your Google Cloud project.
Click Execute.

The following sample response shows the descriptor for this monitored resource:

{
      "type": "gce_instance",
      "displayName": "VM Instance",
      "description": "A virtual machine instance hosted in Compute Engine.",
      "labels": [
        {
          "key": "project_id",
          "description": "The identifier of the Google Cloud project associated with this resource, such as \"my-project\"."
        },
        {
          "key": "instance_id",
          "description": "The numeric VM instance identifier assigned by Compute Engine."
        },
        {
          "key": "zone",
          "description": "The Compute Engine zone in which the VM is running."
        }
      ],
