func SetDefaultSink Uses

func SetDefaultSink(s Sink)

SetDefaultSink sets the sink where binary logs will be written to.

Not thread safe. Only set during initialization.

func SetLogger Uses

func SetLogger(l Logger)

SetLogger sets the binarg logger.

Only call this at init time.

type Cancel Uses

type Cancel struct {
    OnClientSide bool
}

Cancel configs the binary log entry to be a Cancel entry.

type ClientHalfClose Uses

type ClientHalfClose struct {
    OnClientSide bool
}

ClientHalfClose configs the binary log entry to be a ClientHalfClose entry.

type ClientHeader Uses

type ClientHeader struct {
    OnClientSide bool
    Header       metadata.MD
    MethodName   string
    Authority    string
    Timeout      time.Duration
    // PeerAddr is required only when it's on server side.
    PeerAddr net.Addr
}

ClientHeader configs the binary log entry to be a ClientHeader entry.

type ClientMessage Uses

type ClientMessage struct {
    OnClientSide bool
    // Message can be a proto.Message or []byte. Other messages formats are not
    // supported.
    Message interface{}
}

ClientMessage configs the binary log entry to be a ClientMessage entry.

type LogEntryConfig Uses

type LogEntryConfig interface {
    // contains filtered or unexported methods
}

LogEntryConfig represents the configuration for binary log entry.

type Logger Uses

type Logger interface {
    // contains filtered or unexported methods
}

Logger is the global binary logger. It can be used to get binary logger for each method.

func NewLoggerFromConfigString Uses

func NewLoggerFromConfigString(s string) Logger

NewLoggerFromConfigString reads the string and build a logger. It can be used to build a new logger and assign it to binarylog.Logger.

Example filter config strings:

- "" Nothing will be logged
- "*" All headers and messages will be fully logged.
- "*{h}" Only headers will be logged.
- "*{m:256}" Only the first 256 bytes of each message will be logged.
- "Foo/*" Logs every method in service Foo
- "Foo/*,-Foo/Bar" Logs every method in service Foo except method /Foo/Bar
- "Foo/*,Foo/Bar{m:256}" Logs the first 256 bytes of each message in method
  /Foo/Bar, logs all headers and messages in every other method in service
  Foo.

If two configs exist for one certain method or service, the one specified later overrides the privous config.

type MethodLogger Uses

type MethodLogger struct {
    // contains filtered or unexported fields
}

MethodLogger is the sub-logger for each method.

func GetMethodLogger Uses

func GetMethodLogger(methodName string) *MethodLogger

GetMethodLogger returns the methodLogger for the given methodName.

methodName should be in the format of "/service/method".

Each methodLogger returned by this method is a new instance. This is to generate sequence id within the call.

func (*MethodLogger) Log Uses

func (ml *MethodLogger) Log(c LogEntryConfig)

Log creates a proto binary log entry, and logs it to the sink.

type ServerHeader Uses

type ServerHeader struct {
    OnClientSide bool
    Header       metadata.MD
    // PeerAddr is required only when it's on client side.
    PeerAddr net.Addr
}

ServerHeader configs the binary log entry to be a ServerHeader entry.

type ServerMessage Uses

type ServerMessage struct {
    OnClientSide bool
    // Message can be a proto.Message or []byte. Other messages formats are not
    // supported.
    Message interface{}
}

ServerMessage configs the binary log entry to be a ServerMessage entry.

type ServerTrailer Uses

type ServerTrailer struct {
    OnClientSide bool
    Trailer      metadata.MD
    // Err is the status error.
    Err error
    // PeerAddr is required only when it's on client side and the RPC is trailer
    // only.
    PeerAddr net.Addr
}

ServerTrailer configs the binary log entry to be a ServerTrailer entry.

type Sink Uses

type Sink interface {
    // Write will be called to write the log entry into the sink.
    //
    // It should be thread-safe so it can be called in parallel.
    Write(*pb.GrpcLogEntry) error
    // Close will be called when the Sink is replaced by a new Sink.
    Close() error
}

Sink writes log entry into the binary log sink.

func NewTempFileSink Uses

func NewTempFileSink() (Sink, error)

NewTempFileSink creates a temp file and returns a Sink that writes to this file.
