Enum Constant Details

AVAILABILITY

public static final SLOType AVAILABILITY

Successful-attempt fraction over total attempts.

LATENCY

public static final SLOType LATENCY

Fraction of attempts whose latency falls under Target.latencyThresholdMs. Reported as percentage — e.g. p95 invalid input: '<' 3s expressed as "95% of attempts under 3000ms".

ERROR_RATE

public static final SLOType ERROR_RATE

Fraction of attempts that produced an error (any error class). Subset of AVAILABILITY typically, but exposed separately because consumers often want a tighter threshold for error-rate than for raw availability.

CUSTOM

public static final SLOType CUSTOM

User-defined metric. The evaluator reads a custom counter or gauge identified by name. Used as the escape hatch for cost, throughput, queue depth, etc.

Method Details

values

public static SLOType[] 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 SLOType 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
