Method Detail

samplingRate

public double samplingRate()

Returns:

Number between 0 and 1 that more or less reflects the probability of sampling specific trace. 0 and 1 have special meaning here, 0 means never 1 means always. Default value is 0 (never).

includedScopes

@NotNull
public @NotNull Set<Scope> includedScopes()

Returns:

Set of Scope that defines which sub-traces will be included in given trace. In other words, if child's span scope is equals to parent's scope or it belongs to the parent's span included scopes, then given child span will be attached to the current trace, otherwise it'll be skipped. See Span.isChainable(Scope) for more details. If no scopes are specified, empty set will be returned.
