Serialized Fields
-
timestamp
Long timestamp
Epoch microseconds of this event. For example, 1502787600000000 corresponds to 2017-08-15 09:00 UTC This value should be set directly by instrumentation, using the most precise value possible. For example, gettimeofday or multiplying epoch millis by 1000. -
value
String value
Usually a short tag indicating an event, like "error" While possible to add larger data, such as garbage collection details, low cardinality event names both keep the size of spans down and also are easy to search against.

Serialized Fields
-
ipv4
okio.ByteString ipv4
4 byte representation of the primary IPv4 address associated with this connection. Absent if unknown. -
ipv6
okio.ByteString ipv6
16 byte representation of the primary IPv6 address associated with this connection. Absent if unknown. Prefer using the ipv4 field for mapped addresses. -
port
Integer port
Depending on context, this could be a listen port or the client-side of a socket. Absent if unknown. -
service_name
String service_name
Lower-case label of this node in the service graph, such as "favstar". Leave absent if unknown. This is a primary label for trace lookup and aggregation, so it should be intuitive and consistent. Many use a name from service discovery.

Serialized Fields
-
annotations
List<Annotation> annotations
Associates events that explain latency with the time they happened. -
debug
Boolean debug
True is a request to store this span even if it overrides sampling policy. This is true when the "X-B3-Flags" header has a value of 1. -
duration
Long duration
Duration in microseconds of the critical path, if known. Durations of less than one are rounded up. Duration of children can be longer than their parents due to asynchronous operations. For example 150 milliseconds is 150000 microseconds. -
id
okio.ByteString id
Unique identifier for this operation within the trace. This field is required and encoded as 8 opaque bytes. -
kind
Span.Kind kind
When present, used to interpret remote_endpoint -
local_endpoint
Endpoint local_endpoint
The host that recorded this span, primarily for query by service name. Instrumentation should always record this. Usually, absent implies late data. The IP address corresponding to this is usually the site local or advertised service address. When present, the port indicates the listen port. -
name
String name
The logical operation this span represents in lowercase (e.g. rpc method). Leave absent if unknown. As these are lookup labels, take care to ensure names are low cardinality. For example, do not embed variables into the name. -
parent_id
okio.ByteString parent_id
The parent span ID or absent if this the root span in a trace. -
remote_endpoint
Endpoint remote_endpoint
When an RPC (or messaging) span, indicates the other side of the connection. By recording the remote endpoint, your trace will contain network context even if the peer is not tracing. For example, you can record the IP from the "X-Forwarded-For" header or the service name and socket of a remote peer. -
shared
Boolean shared
True if we are contributing to a span started by another tracer (ex on a different host). -
tags
Map<String,String> tags
Tags give your span context for search, viewing and analysis. For example, a key "your_app.version" would let you lookup traces by version. A tag "sql.query" isn't searchable, but it can help in debugging when viewing a trace. -
timestamp
Long timestamp
Epoch microseconds of the start of this span, possibly absent if incomplete. For example, 1502787600000000 corresponds to 2017-08-15 09:00 UTC This value should be set directly by instrumentation, using the most precise value possible. For example, gettimeofday or multiplying epoch millis by 1000. There are three known edge-cases where this could be reported absent. - A span was allocated but never started (ex not yet received a timestamp) - The span's start event was lost - Data about a completed span (ex tags) were sent after the fact -
trace_id
okio.ByteString trace_id
Randomly generated, unique identifier for a trace, set on all spans within it. This field is required and encoded as 8 or 16 bytes, in big endian byte order.
