Enum Constant Summary

Enum Constants

Enum Constant	Description
CONSTANT	Constant sampler always makes the same decision for all traces.
PROBABILISTIC	Probabilistic sampler makes a random sampling decision with the probability of sampling equal to the value of the property.
RATE_LIMITING	Rate Limiting sampler uses a leaky bucket rate limiter to ensure that traces are sampled with a certain constant rate.
REMOTE	Remote sampler consults Jaeger agent for the appropriate sampling strategy to use in the current service.

Method Summary

Modifier and Type	Method	Description
static JaegerTracerBuilder.SamplerType	valueOf(String name)	Returns the enum constant of this class with the specified name.
static JaegerTracerBuilder.SamplerType[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

CONSTANT

public static final JaegerTracerBuilder.SamplerType CONSTANT

Constant sampler always makes the same decision for all traces. It either samples all traces 1 or none of them 0.

PROBABILISTIC

public static final JaegerTracerBuilder.SamplerType PROBABILISTIC

Probabilistic sampler makes a random sampling decision with the probability of sampling equal to the value of the property.

RATE_LIMITING

public static final JaegerTracerBuilder.SamplerType RATE_LIMITING

Rate Limiting sampler uses a leaky bucket rate limiter to ensure that traces are sampled with a certain constant rate.

REMOTE

public static final JaegerTracerBuilder.SamplerType REMOTE

Remote sampler consults Jaeger agent for the appropriate sampling strategy to use in the current service.

Method Details

values

public static JaegerTracerBuilder.SamplerType[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static JaegerTracerBuilder.SamplerType valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
