SpanLimits

Read onlyYes

FinalYes

Configuration limits for span data.

SpanLimits provides bounds on the amount of data a span can collect, preventing unbounded memory growth and ensuring reasonable span sizes.

Example usage:

$limits = new SpanLimits(
    attributeCountLimit: 32,
    eventCountLimit: 128,
    linkCountLimit: 32,
);

// Use defaults
$defaultLimits = SpanLimits::default();

Properties

$attributeCountLimit : int
$attributePerEventCountLimit : int
$attributePerLinkCountLimit : int
$attributeValueLengthLimit : int|null
$eventCountLimit : int
$linkCountLimit : int

Methods

__construct() : mixed
default() : self: Create SpanLimits with default values.
unlimited() : self: Create SpanLimits with unlimited values (for development/debugging).
