Functions

func CtxWith

func CtxWith(ctx context.Context, trigger string) context.Context

CtxWith returns a new context, based on ctx, that embeds argument trigger.

func FromCtx

func FromCtx(ctx context.Context) string

FromCtx returns the trigger embedded in ctx if one exists, or "application" otherwise.

func PeerToLabel

func PeerToLabel(peer net.Addr, local addr.IA) string

PeerToLabel converts the peer address to a peer metric label.

func Timestamp

func Timestamp(ts time.Time) float64

Timestamp return the prometheus value for gauge.
