Opentelemetry Go Instrumentation For Echo

This package provides instrumentation for additional span attributes provided on top of the opentelmetery-instrumentation-echo package.

In order to be able to effectively glean code-object based insights for continuous feedback and map them back in the IDE, Digma inserts additional attribute into the OTEL resource attributes.

Pre-requisites

• Go with Go modules enabled.
• opentelmetery-instrumentation-echo package

Installing the module

go get -u github.com/digma-ai/otel-go-instrumentation/[email protected]

Instrumenting your echo project

The Digma instrumentation depends on the echo opentelemetry instrumentation.

Make sure the digmaecho middleware goes after the otelecho middleware

import (
	digmaecho "github.com/digma-ai/otel-go-instrumentation/echo"
	"go.opentelemetry.io/contrib/instrumentation/github.com/labstack/echo/otelecho"
)


func main() {
	r := echo.New()
	r.Use(otelecho.Middleware(appName))
	r.Use(digmaecho.Middleware())
	r.GET("/", index)
}
