NAME

OpenTelemetry::SDK::Trace::Sampler::AlwaysOn - A sampler that will always sample

SYNOPSIS

my $sampler = OpenTelemetry::SDK::Trace::Sampler::AlwaysOn->new;

my $result = $sampler->should_sample( ... );

unless ( $result->sampled ) {
    # this will never be reached :(
}

DESCRIPTION

This module provides a sampler whose should_sample method will always return a result that is both sampled and recording.

METHODS

This class implements the OpenTelemetry::SDK::Trace::Sampler role. Please consult that module's documentation for details on the behaviours it provides.

new

$sampler = OpenTelemetry::SDK::Trace::Sampler::AlwaysOn->new;

Returns a new instance of this sampler. Takes no arguments.

description

$string = $sampler->description;

Returns the AlwaysOnSampler string.

should_sample

$result = $sampler->should_sample(
    context    => $context,
    trace_id   => $trace_id,
    kind       => $span_kind,
    name       => $span_name,
    attributes => \%attributes,
    links      => \@links,
);

Returns a OpenTelemetry::SDK::Trace::Sampler::Result that is both sampled and recording. The OpenTelemetry::Propagator::TraceContext::TraceState in the result will be read from the context provided in the context parameter, or from the current context if none is provided.
