public sealed class TraceSpan : IMessage<TraceSpan>, IEquatable<TraceSpan>, IDeepCloneable<TraceSpan>, IBufferMessage, IMessage
Reference documentation and code samples for the Google Cloud Trace v1 API class TraceSpan.
A span represents a single timed event within a trace. Spans can be nested and form a trace tree. Often, a trace contains a root span that describes the end-to-end latency of an operation and, optionally, one or more subspans for its suboperations. Spans do not need to be contiguous. There may be gaps between spans in a trace.

Properties
EndTime
public Timestamp EndTime { get; set; }
End time of the span in nanoseconds from the UNIX epoch.

Type | Description |
Timestamp |
Kind
public TraceSpan.Types.SpanKind Kind { get; set; }
Distinguishes between spans generated in a particular context. For example,
two spans with the same name may be distinguished using RPC_CLIENT
and RPC_SERVER
to identify queueing latency associated with the span.

Labels
public MapField<string, string> Labels { get; }
Collection of labels associated with the span. Label keys must be less than
128 bytes. Label values must be less than 16 kilobytes (10MB for
/stacktrace
values).
Some predefined label keys exist, or you may create your own. When creating your own, we recommend the following formats:
/category/product/key
for agents of well-known products (e.g./db/mongodb/read_size
).short_host/path/key
for domain-specific keys (e.g.foo.com/myproduct/bar
)
Predefined labels include:
/agent
/component
/error/message
/error/name
/http/client_city
/http/client_country
/http/client_protocol
/http/client_region
/http/host
/http/method
/http/path
/http/redirected_url
/http/request/size
/http/response/size
/http/route
/http/status_code
/http/url
/http/user_agent
/pid
/stacktrace
/tid

Name
public string Name { get; set; }
Name of the span. Must be less than 128 bytes. The span name is sanitized and displayed in the Stackdriver Trace tool in the Google Cloud Platform Console. The name may be a method name or some other per-call site name. For the same executable and the same call point, a best practice is to use a consistent name, which makes it easier to correlate cross-trace spans.

ParentSpanId
public ulong ParentSpanId { get; set; }
Optional. ID of the parent span, if any.

Type | Description |

SpanId
public ulong SpanId { get; set; }
Identifier for the span. Must be a 64-bit integer other than 0 and
unique within a trace. For example, 2205310701640571284
.
