Functions

func Configure 

func Configure(out io.Writer, format string, level string, hooks ...logrus.Hook) logrus.FieldLogger

Configure configures the default and gRPC loggers. The gRPC logger's log level will be mapped in order to decrease its default verbosity. Returns the configured default logger that would also be returned by `Default()`.

func DeciderOption 

func DeciderOption() grpcmwlogrus.Option

DeciderOption returns a Option to support log filtering. If "GITALY_LOG_REQUEST_METHOD_DENY_PATTERN" ENV variable is set, logger will filter out the log whose "fullMethodName" matches it; If "GITALY_LOG_REQUEST_METHOD_ALLOW_PATTERN" ENV variable is set, logger will only keep the log whose "fullMethodName" matches it; Under any conditions, the error log will not be filtered out; If the ENV variables are not set, there will be no additional effects.

func Default 

func Default() *logrus.Entry

Default returns the default logger that has been configured via `Configure()`.

func InitContextCustomFields added in v16.2.0 

func InitContextCustomFields(ctx context.Context) context.Context

InitContextCustomFields returns a new context with `CustomFields` added to the given context.

func MessageProducer 

func MessageProducer(mp grpcmwlogrus.MessageProducer, fieldsProducers ...FieldsProducer) grpcmwlogrus.MessageProducer

MessageProducer returns a wrapper that extends passed mp to accept additional fields generated by each of the fieldsProducers.

func PropagationMessageProducer 

func PropagationMessageProducer(actual grpcmwlogrus.MessageProducer) grpcmwlogrus.MessageProducer

PropagationMessageProducer catches logging information from the context and populates it to the special holder that should be present in the context. Should be used only in combination with PerRPCLogHandler.

func StreamLogDataCatcherServerInterceptor 

func StreamLogDataCatcherServerInterceptor() grpc.StreamServerInterceptor

StreamLogDataCatcherServerInterceptor catches logging data produced by the upper interceptors and propagates it into the holder to pop up it to the HandleRPC method of the PerRPCLogHandler.

func UTCJsonFormatter 

func UTCJsonFormatter() logrus.Formatter

UTCJsonFormatter returns a Formatter that formats a logrus Entry's as json and converts the time field into UTC

func UTCTextFormatter 

func UTCTextFormatter() logrus.Formatter

UTCTextFormatter returns a Formatter that formats a logrus Entry's as text and converts the time field into UTC

func UnaryLogDataCatcherServerInterceptor 

func UnaryLogDataCatcherServerInterceptor() grpc.UnaryServerInterceptor

UnaryLogDataCatcherServerInterceptor catches logging data produced by the upper interceptors and propagates it into the holder to pop up it to the HandleRPC method of the PerRPCLogHandler.

Types

type Config added in v16.3.0 

type Config struct {
	Dir    string `toml:"dir,omitempty" json:"dir"`
	Format string `toml:"format,omitempty" json:"format"`
	Level  string `toml:"level,omitempty" json:"level"`
}

Config contains logging configuration values

type CustomFields added in v16.2.0 

type CustomFields struct {
	sync.Mutex
	// contains filtered or unexported fields
}

CustomFields stores custom fields, which will be logged as a part of gRPC logs. The gRPC server is expected to add corresponding interceptors. They initialize a CustomFields object and inject it into the context. Callers can pull the object out with CustomFieldsFromContext.

func CustomFieldsFromContext added in v16.2.0 

func CustomFieldsFromContext(ctx context.Context) *CustomFields

CustomFieldsFromContext gets the `CustomFields` from the given context.

func (*CustomFields) Fields added in v16.2.0 

func (fields *CustomFields) Fields() logrus.Fields

Fields returns all the fields as logrus.Fields

func (*CustomFields) RecordMax added in v16.2.0 

func (fields *CustomFields) RecordMax(key string, value int)

RecordMax will store the max value for a given key.

func (*CustomFields) RecordMetadata added in v16.2.0 

func (fields *CustomFields) RecordMetadata(key string, value any)

RecordMetadata records a string metadata for the given key.

func (*CustomFields) RecordSum added in v16.2.0 

func (fields *CustomFields) RecordSum(key string, value int)

RecordSum sums up all the values for a given key.

type FieldsProducer 

type FieldsProducer func(context.Context, error) logrus.Fields

FieldsProducer returns fields that need to be added into the logging context. error argument is the result of RPC handling.

type PerRPCLogHandler 

type PerRPCLogHandler struct {
	Underlying     stats.Handler
	FieldProducers []FieldsProducer
}

PerRPCLogHandler is designed to collect stats that are accessible from the google.golang.org/grpc/stats.Handler, because some information can't be extracted on the interceptors level.

func (PerRPCLogHandler) HandleConn 

func (lh PerRPCLogHandler) HandleConn(ctx context.Context, cs stats.ConnStats)

HandleConn only calls Underlying and exists to satisfy gRPC stats.Handler.

func (PerRPCLogHandler) HandleRPC 

func (lh PerRPCLogHandler) HandleRPC(ctx context.Context, rs stats.RPCStats)

HandleRPC catches each RPC call and for the *stats.End stats invokes custom message producers to populate logging data. Once all data is collected the actual logging happens by using logger that is caught by PropagationMessageProducer.

func (PerRPCLogHandler) TagConn 

func (lh PerRPCLogHandler) TagConn(ctx context.Context, cti *stats.ConnTagInfo) context.Context

TagConn only calls Underlying and exists to satisfy gRPC stats.Handler.

func (PerRPCLogHandler) TagRPC 

func (lh PerRPCLogHandler) TagRPC(ctx context.Context, rti *stats.RPCTagInfo) context.Context

TagRPC propagates a special data holder into the context that is responsible to hold logging information produced by the logging interceptor. The logging data should be caught by the UnaryLogDataCatcherServerInterceptor. It needs to be included into the interceptor chain below logging interceptor.

type URLSanitizerHook added in v16.3.0 

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

URLSanitizerHook stores which gRPC methods to perform sanitization for.

func NewURLSanitizerHook added in v16.3.0 

func NewURLSanitizerHook() *URLSanitizerHook

NewURLSanitizerHook returns a new logrus hook for sanitizing URLs.

func (*URLSanitizerHook) AddPossibleGrpcMethod added in v16.3.0 

func (hook *URLSanitizerHook) AddPossibleGrpcMethod(methods ...string)

AddPossibleGrpcMethod adds method names that we should sanitize URLs from their logs.

func (*URLSanitizerHook) Fire added in v16.3.0 

func (hook *URLSanitizerHook) Fire(entry *logrus.Entry) error

Fire is called by logrus.

func (*URLSanitizerHook) Levels added in v16.3.0 

func (hook *URLSanitizerHook) Levels() []logrus.Level

Levels is called by logrus.
