Tutorial: View HyperSDK traces locally

[RodrigoVillar]

This tutorial will show you how to view the OpenTelemetry traces from MorpheusVM.

Prerequisites

• You'll need to use the remove-zipkin-exporter branch of HyperSDK
• You'll need to use the RodrigoVillar:add-unmarshal-for-exportertype branch from here: https://github.com/RodrigoVillar/avalanchego
• Docker
  • I used OrbStack, but you could probably use Docker Desktop as well

Steps

First, you'll need to enable tracing in MorpheusVM. In vm/config.go, set TraceConfig to the following:

TraceConfig: trace.Config{
			Enabled:         true,
			AppName:         "MorpheusVM",
			TraceSampleRate: 1.0,
			ExporterConfig: trace.ExporterConfig{
				Type:     trace.GRPC,
				Endpoint: "localhost:4317",
				Insecure: true,
			},
		},

Next, inside of MorpheusVM, start it up using ./scripts/run.sh. Next, start up jaeger using the following:

docker run -d --name jaeger -p 16686:16686 -p 4317:4317 jaegertracing/all-in-one:latest

Finally, head to http://localhost:16686/ where you should see the jaeger frontend. If all works well, you should be able to select MorpheusVM from the service dropdown
