Opentelemetry types and instrumentation

module Lock : sig ... end

Global lock.

module Rand_bytes : sig ... end

Generation of random identifiers.

module AList : sig ... end

Atomic list, for internal usage

Wire format

module Proto = Opentelemetry_proto

Protobuf types.

Collector types

Identifiers

module Trace_id : sig ... end

Trace ID.

val k_trace_id : Trace_id.t Hmap.key

Hmap key to carry around a Trace_id.t, to remember what the current trace is.

since 0.8

module Span_id : sig ... end

module Span_ctx : sig ... end

Span context. This bundles up a trace ID and parent ID.

val k_span_ctx : Span_ctx.t Hmap.key

Hmap key to carry around a Span_ctx.t, e.g. to remember what the current parent span is.

since 0.8

Attributes and conventions

module Conventions : sig ... end

Semantic conventions

type value = [

| `Int of int
| `String of string
| `Bool of bool
| `Float of float
| `None

]

A value in a key/value attribute

type key_value = string * value
