dgdao-telemetry

An OpenTelemetry-backed tracer for the dgdao typed client. The typed client traces every database operation through a pluggable typed.Tracer (a no-op by default); this package provides the OpenTelemetry implementation.

Install

go get github.com/dgraph-io/dgdao-telemetry

Usage

Install the tracer once at startup, after configuring your OpenTelemetry SDK and exporter:

import (
    "github.com/dgraph-io/dgdao/typed"
    telemetry "github.com/dgraph-io/dgdao-telemetry"
)

func main() {
    // ... configure your OpenTelemetry SDK / exporter ...
    typed.SetTracer(telemetry.New())
}

Each typed database operation then emits a dgdao.<op> client span carrying the Dgraph database semantic attributes db.system=dgraph, db.operation.name, and db.collection.name. With no SDK installed in the process the spans are no-ops.
