Field Detail

CLIENT_SEND

public static final java.lang.String CLIENT_SEND

Deprecated.

The client sent ("cs") a request to a server. There is only one send per span. For example, if there's a transport error, each attempt can be logged as a WIRE_SEND annotation. If chunking is involved, each chunk could be logged as a separate CLIENT_SEND_FRAGMENT in the same span. Annotation.host is not the server. It is the host which logged the send event, almost always the client. When logging CLIENT_SEND, instrumentation should also log the SERVER_ADDR.

Constant Field Values

CLIENT_RECV

public static final java.lang.String CLIENT_RECV

Deprecated.

The client received ("cr") a response from a server. There is only one receive per span. For example, if duplicate responses were received, each can be logged as a WIRE_RECV annotation. If chunking is involved, each chunk could be logged as a separate CLIENT_RECV_FRAGMENT in the same span. Annotation.host is not the server. It is the host which logged the receive event, almost always the client. The actual endpoint of the server is recorded separately as SERVER_ADDR when CLIENT_SEND is logged.

See Also:

Constant Field Values

SERVER_SEND

public static final java.lang.String SERVER_SEND

Deprecated.

The server sent ("ss") a response to a client. There is only one response per span. If there's a transport error, each attempt can be logged as a WIRE_SEND annotation. Typically, a trace ends with a server send, so the last timestamp of a trace is often the timestamp of the root span's server send. If chunking is involved, each chunk could be logged as a separate SERVER_SEND_FRAGMENT in the same span. Annotation.host is not the client. It is the host which logged the send event, almost always the server. The actual endpoint of the client is recorded separately as CLIENT_ADDR when SERVER_RECV is logged.

See Also:

Constant Field Values

SERVER_RECV

public static final java.lang.String SERVER_RECV

Deprecated.

The server received ("sr") a request from a client. There is only one request per span. For example, if duplicate responses were received, each can be logged as a WIRE_RECV annotation. Typically, a trace starts with a server receive, so the first timestamp of a trace is often the timestamp of the root span's server receive. If chunking is involved, each chunk could be logged as a separate SERVER_RECV_FRAGMENT in the same span. Annotation.host is not the client. It is the host which logged the receive event, almost always the server. When logging SERVER_RECV, instrumentation should also log the CLIENT_ADDR.

Constant Field Values

WIRE_SEND

public static final java.lang.String WIRE_SEND

Deprecated.

Optionally logs an attempt to send a message on the wire. Multiple wire send events could indicate network retries. A lag between client or server send and wire send might indicate queuing or processing delay.

Constant Field Values

WIRE_RECV

public static final java.lang.String WIRE_RECV

Deprecated.

Optionally logs an attempt to receive a message from the wire. Multiple wire receive events could indicate network retries. A lag between wire receive and client or server receive might indicate queuing or processing delay.

See Also:

Constant Field Values

CLIENT_SEND_FRAGMENT

public static final java.lang.String CLIENT_SEND_FRAGMENT

Deprecated.

Optionally logs progress of a (CLIENT_SEND, WIRE_SEND). For example, this could be one chunk in a chunked request.

See Also:

Constant Field Values

CLIENT_RECV_FRAGMENT

public static final java.lang.String CLIENT_RECV_FRAGMENT

Deprecated.

Optionally logs progress of a (CLIENT_RECV, WIRE_RECV). For example, this could be one chunk in a chunked response.

Constant Field Values

SERVER_SEND_FRAGMENT

public static final java.lang.String SERVER_SEND_FRAGMENT

Deprecated.

Optionally logs progress of a (SERVER_SEND, WIRE_SEND). For example, this could be one chunk in a chunked response.

Constant Field Values

SERVER_RECV_FRAGMENT

public static final java.lang.String SERVER_RECV_FRAGMENT

Deprecated.

Optionally logs progress of a (SERVER_RECV, WIRE_RECV). For example, this could be one chunk in a chunked request.

See Also:

Constant Field Values

CLIENT_ADDR

public static final java.lang.String CLIENT_ADDR

Deprecated.

Indicates a client address ("ca") in a span. Most likely, there's only one. Multiple addresses are possible when a client changes its ip or port within a span.

See Also:

Constant Field Values

SERVER_ADDR

public static final java.lang.String SERVER_ADDR

Deprecated.

Indicates a server address ("sa") in a span. Most likely, there's only one. Multiple addresses are possible when a client is redirected, or fails to a different server ip or port.

See Also:

Constant Field Values

LOCAL_COMPONENT

public static final java.lang.String LOCAL_COMPONENT

Deprecated.

The value of "lc" is the component or namespace of a local span.

BinaryAnnotation.host adds service context needed to support queries.

Local Component("lc") supports three key features: flagging, query by service and filtering Span.name by namespace.

While structurally the same, local spans are fundamentally different than RPC spans in how they should be interpreted. For example, zipkin v1 tools center on RPC latency and service graphs. Root local-spans are neither indicative of critical path RPC latency, nor have impact on the shape of a service graph. By flagging with "lc", tools can special-case local spans.

Zipkin v1 Spans are unqueryable unless they can be indexed by service name. The only path to a service name is via host. By logging "lc", a local span can be queried even if no other annotations are logged.

The value of "lc" is the namespace of Span.name. For example, it might be "finatra2", for a span named "bootstrap". "lc" allows you to resolves conflicts for the same Span.name, for example "finatra/bootstrap" vs "finch/bootstrap". Using local component, you'd search for spans named "bootstrap" where "lc=finch"
