public sealed class MonitoredResourceMetadata : IMessage<MonitoredResourceMetadata>, IEquatable<MonitoredResourceMetadata>, IDeepCloneable<MonitoredResourceMetadata>, IBufferMessage, IMessage
Auxiliary metadata for a [MonitoredResource][google.api.MonitoredResource]
object. [MonitoredResource][google.api.MonitoredResource] objects contain the
minimum set of information to uniquely identify a monitored resource
instance. There is some other useful auxiliary metadata. Monitoring and
Logging use an ingestion pipeline to extract metadata for cloud resources of
all types, and store the metadata in this message.
Output only. Values for predefined system metadata labels.
System labels are a kind of metadata extracted by Google, including
"machine_image", "vpc", "subnet_id",
"security_group", "name", etc.
System label values can be only strings, Boolean values, or a list of
strings. For example:
