Enum Class DurationInstrumentationMode

java.lang.Object

java.lang.Enum<DurationInstrumentationMode>

io.github.teceli.resiliencia.opentelemetry.DurationInstrumentationMode

All Implemented Interfaces:

Serializable, Comparable<DurationInstrumentationMode>, Constable

public enum DurationInstrumentationMode
extends Enum<DurationInstrumentationMode>

How OpenTelemetryResilienceMetrics records duration metrics (resilience.timeout.duration, resilience.circuitbreaker.calls).

Unlike Micrometer's percentile histograms, there is no "don't opt in" lever available to resiliencia's own code for the OTel SDK's default histogram aggregation: DoubleExplicitBucketHistogramAggregator synchronizes on every recorded value, unconditionally (see docs/architecture/metrics/metrics.md's "Backend audit" section). This closed, two-value enum keeps the safe default enforced by the API shape itself, rather than a consumer-supplied strategy that could reintroduce the same unbounded risk.

Enum Constant Summary

Enum Constants

Enum Constant	Description
DETAILED	Duration recorded via DoubleHistogram.record(...), yielding full percentile/ distribution data, with the documented per-call synchronized pinning risk from the OTel SDK's default explicit-bucket histogram aggregation.
SAFE	Duration recorded as a lock-free counter pair — a count and a summed duration, both backed by LongSumAggregator/DoubleSumAggregator.

Method Summary

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

Enum Constant Details

SAFE

public static final DurationInstrumentationMode SAFE

Duration recorded as a lock-free counter pair — a count and a summed duration, both backed by LongSumAggregator/DoubleSumAggregator. Mean is derivable (sum / count) by the backend at query time; no percentile/distribution data; zero per-call pinning risk by construction. Default.

DETAILED

public static final DurationInstrumentationMode DETAILED

Duration recorded via DoubleHistogram.record(...), yielding full percentile/ distribution data, with the documented per-call synchronized pinning risk from the OTel SDK's default explicit-bucket histogram aggregation. Explicit opt-in only.

Method Details

values

public static DurationInstrumentationMode[] 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 DurationInstrumentationMode 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
