Functions

func Register

func Register(name string, info PackageInfo) error

Types

type Component

type Component int

const (
	ComponentDefault Component = iota
	ComponentServer
	ComponentClient
	ComponentProducer
	ComponentConsumer
)

type HeaderTags

type HeaderTags interface {
	Iter(f func(header string, tag string))
}

func NewHeaderTags

func NewHeaderTags(headers []string) HeaderTags

type Instrumentation

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

Instrumentation represents instrumentation for a package.

func Load

func Load(pkg Package) *Instrumentation

Load attempts to load the requested package instrumentation. It panics if the package has not been registered.

func (*Instrumentation) AnalyticsRate

func (i *Instrumentation) AnalyticsRate(defaultGlobal bool) float64

func (*Instrumentation) AppSecEnabled

func (i *Instrumentation) AppSecEnabled() bool

func (*Instrumentation) AppSecRASPEnabled

func (i *Instrumentation) AppSecRASPEnabled() bool

func (*Instrumentation) DataStreamsEnabled

func (i *Instrumentation) DataStreamsEnabled() bool

func (*Instrumentation) GlobalAnalyticsRate

func (i *Instrumentation) GlobalAnalyticsRate() float64

func (*Instrumentation) HTTPHeadersAsTags

func (i *Instrumentation) HTTPHeadersAsTags() HeaderTags

func (*Instrumentation) Logger

func (i *Instrumentation) Logger() Logger

func (*Instrumentation) OperationName

func (i *Instrumentation) OperationName(component Component, opCtx OperationContext) string

OperationName returns the operation name to be set for the given instrumentation component.

func (*Instrumentation) ServiceName

func (i *Instrumentation) ServiceName(component Component, opCtx OperationContext) string

ServiceName returns the default service name to be set for the given instrumentation component.

func (*Instrumentation) StatsdClient

func (i *Instrumentation) StatsdClient(extraTags []string) (StatsdClient, error)

func (*Instrumentation) TracerInitialized

func (i *Instrumentation) TracerInitialized() bool

TracerInitialized returns whether the global tracer has been initialized or not.

func (*Instrumentation) WithExecutionTraced

func (i *Instrumentation) WithExecutionTraced(ctx context.Context) context.Context

WithExecutionTraced marks ctx as being associated with an execution trace task. It is assumed that ctx already contains a trace task. The caller is responsible for ending the task.

This is intended for a specific case where the database/sql contrib package only creates spans *after* an operation, in case the operation was unavailable, and thus execution trace tasks tied to the span only capture the very end. This function enables creating a task *before* creating a span, and communicating to the APM tracer that it does not need to create a task. In general, APM instrumentation should prefer creating tasks around the operation rather than after the fact, if possible.

type Logger

type Logger interface {
	Debug(msg string, args ...any)
	Info(msg string, args ...any)
	Warn(msg string, args ...any)
	Error(msg string, args ...any)
}

type OperationContext

type OperationContext map[string]string

OperationContext holds metadata about an instrumentation operation.
