MonitoredResource

An object representing a resource that can be used for monitoring, logging, billing, or other purposes. Examples include virtual machine instances, databases, and storage devices such as disks. The type field identifies a MonitoredResourceDescriptor object that describes the resource's schema. Information in the labels field identifies the actual resource and its attributes according to the schema. For example, a particular Compute Engine VM instance could be represented by the following object, because the MonitoredResourceDescriptor for "gce_instance" has labels "project_id", "instance_id" and "zone":

{ "type": "gce_instance",
  "labels": { "project_id": "my-project",
              "instance_id": "12345678901234",
              "zone": "us-central1-a" }}

Fields
type

string

Required. The monitored resource type. This field must match the type field of a MonitoredResourceDescriptor object. For example, the type of a Compute Engine VM instance is gce_instance. Some descriptors include the service name in the type; for example, the type of a Datastream stream is datastream.googleapis.com/Stream.
labels

map (key: string, value: string)

Required. Values for all of the labels listed in the associated monitored resource descriptor. For example, Compute Engine VM instances use the labels "project_id", "instance_id", and "zone".
