func NewClient(opt *redis.Options, opts ...ClientOption) *Client

NewClient returns a new Client that is traced with the default tracer under the service name "redis".

func WrapClient added in v1.0.0

func WrapClient(c *redis.Client, opts ...ClientOption) *Client

WrapClient wraps a given redis.Client with a tracer under the given service name.

func (*Client) Pipeline added in v1.0.0

func (c *Client) Pipeline() redis.Pipeliner

Pipeline creates a Pipeline from a Client

func (*Client) WithContext added in v1.0.0

func (c *Client) WithContext(ctx context.Context) *Client

WithContext sets a context on a Client. Use it to ensure that emitted spans have the correct parent.

type ClientOption added in v1.0.0

type ClientOption func(*clientConfig)

ClientOption represents an option that can be used to create or wrap a client.

func WithAnalytics added in v1.11.0

func WithAnalytics(on bool) ClientOption

WithAnalytics enables Trace Analytics for all started spans.

func WithAnalyticsRate added in v1.11.0

func WithAnalyticsRate(rate float64) ClientOption

WithAnalyticsRate sets the sampling rate for Trace Analytics events correlated to started spans.

func WithServiceName added in v1.0.0

func WithServiceName(name string) ClientOption

WithServiceName sets the given service name for the client.

type Pipeliner added in v1.0.0

type Pipeliner struct {
	redis.Pipeliner
	// contains filtered or unexported fields
}

Pipeliner is used to trace pipelines executed on a Redis server.

func (*Pipeliner) Exec added in v1.0.0

func (c *Pipeliner) Exec() ([]redis.Cmder, error)

Exec calls Pipeline.Exec() ensuring that the resulting Redis calls are traced.

func (*Pipeliner) ExecWithContext added in v1.0.0

func (c *Pipeliner) ExecWithContext(ctx context.Context) ([]redis.Cmder, error)

ExecWithContext calls Pipeline.Exec(). It ensures that the resulting Redis calls are traced, and that emitted spans are children of the given Context.
