Functions

func GetAttributesForDeployment

func GetAttributesForDeployment(deployment *appsv1.Deployment) []attribute.KeyValue

func GetAttributesForEnv

func GetAttributesForEnv(env *fv1.Environment) []attribute.KeyValue

func GetAttributesForFunction

func GetAttributesForFunction(fn *fv1.Function) []attribute.KeyValue

GetAttributesForFunction returns a set of attributes for a function. Attributes returned:
   function-name
   function-namespace
   environment-name

func GetAttributesForSvc

func GetAttributesForSvc(svc *apiv1.Service) []attribute.KeyValue

func GetHandlerWithOTEL

func GetHandlerWithOTEL(h http.Handler, name string, filter ...otelhttp.Filter) http.Handler

func InitProvider

func InitProvider(ctx context.Context, logger *zap.Logger, serviceName string) (func(context.Context), error)

Initializes an OTLP exporter, and configures the corresponding trace and metric providers.

func LoggerWithTraceID

func LoggerWithTraceID(ctx context.Context, logger *zap.Logger) *zap.Logger

func MapToAttributes

func MapToAttributes(m map[string]string) []attribute.KeyValue

func OtelEnvForContainer

func OtelEnvForContainer() []apiv1.EnvVar

OtelEnvForContainer returns a list of environment variables for the container, which start with prefix OTEL_

func SpanTrackEvent

func SpanTrackEvent(ctx context.Context, event string, attributes ...attribute.KeyValue)

func UrlsToIgnore

func UrlsToIgnore(ignoreEndpoints ...string) func(r *http.Request) bool
