public sealed class AttributeContext : IMessage<AttributeContext>, IEquatable<AttributeContext>, IDeepCloneable<AttributeContext>, IBufferMessage, IMessage
This message defines the standard attribute vocabulary for Google APIs.
An attribute is a piece of metadata that describes an activity on a network
service. For example, the size of an HTTP request, or the status code of
an HTTP response.
Each attribute has a type and a name, which is logically defined as
a proto message field in AttributeContext. The field type becomes the
attribute type, and the field path becomes the attribute name. For example,
the attribute source.ip maps to field AttributeContext.source.ip.
This message definition is guaranteed not to have any wire breaking change.
So you can use it directly for passing attributes across different systems.
NOTE: Different system may generate different subset of attributes. Please
verify the system specification before relying on an attribute generated
a system.
public AttributeContext.Types.Peer Destination { get; set; }
The destination of a network activity, such as accepting a TCP connection.
In a multi hop network activity, the destination represents the receiver of
the last hop.
public AttributeContext.Types.Peer Origin { get; set; }
The origin of a network activity. In a multi hop network activity,
the origin represents the sender of the first hop. For the first hop,
the source and the origin must have the same content.
public AttributeContext.Types.Resource Resource { get; set; }
Represents a target resource that is involved with a network activity.
If multiple resources are involved with an activity, this must be the
primary one.
public AttributeContext.Types.Peer Source { get; set; }
The source of a network activity, such as starting a TCP connection.
In a multi hop network activity, the source represents the sender of the
last hop.
