Monitor Labstack Echo with OpenTelemetry
Echo is a high performance, extensible, minimalist web framework for Go. It features a highly optimized HTTP router with zero dynamic memory allocations.
In this article you will learn how to monitor and optimize Echo performance using OpenTelemetry Echo instrumentation.
What is OpenTelemetry?
OpenTelemetry is an open source and vendor-neutral API for OpenTelemetry tracing, logs, and metrics.
OpenTelemetry provides a set of APIs, libraries, and instrumentation tools to instrument applications and collect data about their behavior and performance.
The goal of OpenTelemetry is to provide a standardized and vendor agnostic way to instrument applications for observability, for example, many open source tracing tools already support OpenTelemetry.
Echo instrumentation
To install otelecho instrumentation:
go get go.opentelemetry.io/contrib/instrumentation/github.com/labstack/echo/otelecho
Usage
You can instrument Gin router by installing OpenTelemetry middleware:
import (
"github.com/labstack/echo/v4"
"go.opentelemetry.io/contrib/instrumentation/github.com/labstack/echo/otelecho"
)
router := echo.New()
router.Use(otelecho.Middleware("service-name"))
What is Uptrace?
Uptrace is a OpenTelemetry backend that supports distributed tracing, metrics, and logs. You can use it to monitor applications and troubleshoot issues.
Uptrace comes with an intuitive query builder, rich dashboards, alerting rules with notifications, and integrations for most languages and frameworks.
Uptrace can process billions of spans and metrics on a single server and allows you to monitor your applications at 10x lower cost.
In just a few minutes, you can try Uptrace by visiting the cloud demo (no login required) or running it locally with Docker. The source code is available on GitHub.
What's next?
Next, instrument more operations to get a more detailed picture. Try to prioritize network calls, disk operations, database queries, error and logs.
You can also create your own instrumentations using OpenTelemetry Go Tracing API.
