Optional. Data for populating the Message object.
↳ capture_time
↳ type
↳ metadata
↳ server_metadata
ServerMetadata
Output only. Metadata that the server appends to each packet before sending it to receivers. You don't need to set a value for this field when sending packets.
↳ series_metadata
SeriesMetadata
Input only. Immutable. Metadata that the server needs to know where to write the packets to. It's only required for the first packet.
↳ flags
int
Immutable. Packet flag set. SDK will set the flag automatically.
↳ trace_context
string
Immutable. Header string for tracing across services. It should be set when the packet is first arrived in the stream server. The input format is a lowercase hex string: - version_id: 1 byte, currently must be zero - hex encoded (2 characters) - trace_id: 16 bytes (opaque blob) - hex encoded (32 characters) - span_id: 8 bytes (opaque blob) - hex encoded (16 characters) - trace_options: 1 byte (LSB means tracing enabled) - hex encoded (2 characters) Example: "00-404142434445464748494a4b4c4d4e4f-6162636465666768-01" v trace_id span_id options
