Modules

otel_batch_processor

The Batch Span Processor implements the otel_span_processor behaviour.

otel_events
otel_exporter
otel_exporter_pid
A test exporter for sending trace spans to an Erlang PID as message.
otel_exporter_stdout
Exporter that prints spans to stdout.
otel_exporter_tab
A test reporter that keeps finished spans in an ETS table.
otel_exporter_traces
otel_id_generator
This module provides the behaviour to implement for custom trace and span id generation and the default implementation of the generators which produces random 128 bit and 64 bit integers for the trace id and span id.
otel_links
otel_resource

A Resource is attributes representing the entity producing telemetry. For example, by default the language (Erlang), name of this library (opentelemetry), and version of this library are included in the Resource.

otel_resource_app_env

Resource detector (otel_resource_detector) which adds attributes to the Resource based on the value of resource in the opentelemetry application's environment.

otel_resource_detector

Resource detectors are responsible for reading in attributes about the runtime environment of a node (such as an environment variable or some metadata endpoint provided by a cloud host) and returning a otel_resource:t() made from those attributes.

otel_resource_env_var

Resource detector (otel_resource_detector) which adds attributes to the Resource based on environment variables.

otel_sampler

Behaviour for defining samplers.

otel_sampler_always_off

An otel_sampler that drops all spans.

otel_sampler_always_on

An otel_sampler that records and samples all spans.

otel_sampler_parent_based

An otel_sampler that makes the decision based on the parent.

otel_sampler_trace_id_ratio_based

An otel_sampler that samples a configured percentage of spans.

otel_simple_processor

This Span Processor synchronously exports each ended Span.

otel_span_ets
ETS backed interface for working with spans.
otel_span_limits
Module for setting the global limits for the number of attributes, events and links on a Span.
otel_span_processor
Behaviour each Span Processor must implement.
otel_span_sweeper
The span sweeper is a process that can be configured to remove, either by finishing or deleting, spans that are still active after a period of time.
otel_tracer_default
otel_tracer_server
This module is the SDK's implementation of the TracerProvider. The calls to the server are done from the API module otel_tracer_provider. This gen_server is started as part of the SDK's supervision tree and registers itself as the default TracerProvider by using the name otel_tracer_provider as its name.
