README

OpenTelemetry instrumentation for gqlgen

This library provides OpenTelemetry (OTEL) instrumentation for gqlgen server requests.

Installation

Add the package to your project:

go get github.com/zhevron/gqlgen-opentelemetry

Usage

Add the gqlgen_opentelemetry.Tracer extension to your server:

h := handler.NewDefaultServer(schema)
h.Use(gqlgen_opentelemetry.Tracer{})

Options

The following options are available on the extension:

IncludeFieldSpans: Whether to create an additional child span for each field requested. (Default: false)

IncludeVariables: Whether to include variables and their values in the trace span attributes. (Default: false)

TracerProvider: The OTEL tracer provider to instantiate a tracer from. If none is provided, the global OTEL tracer provider will be used.
