OpenTelemetry Gin Monitoring [otelgin]

OpenTelemetry Gin can help developers monitor and diagnose issues with their Gin applications, and can provide valuable insights into the behavior of the applications in production.

What is Gin?

Gin is a lightweight web framework for building web applications and APIs in the Go programming language. It provides a minimalist and fast approach to building web applications, emphasizing simplicity, performance, and ease of use.

Gin's simplicity and performance make it a popular choice for building web applications and APIs in Go. It provides a solid foundation for developing scalable and efficient web services while maintaining a straightforward and intuitive API.

What is OpenTelemetry?

OpenTelemetry is an open-source observability framework that aims to standardize and simplify the collection, processing, and export of telemetry data from applications and systems.

OpenTelemetry supports multiple programming languages and platforms, making it suitable for a wide range of applications and environments.

OpenTelemetry enables developers to instrument their code and collect telemetry data, which can then be exported to various OpenTelemetry backends or observability platforms for analysis and visualization. The OpenTelemetry architecture is built with modularity and flexibility, allowing it to work seamlessly across different programming languages and frameworks.

Gin instrumentation

Gin OpenTelemetry instrumentation allows developers to easily add observability to their Gin applications, providing insights into application performance, behavior, and usage patterns.

OpenTelemetry Gin provides a simple API for instrumenting Gin applications, making it possible for developers to quickly add observability to their applications without having to write a lot of code.

To install otelgin instrumentation:

go get go.opentelemetry.io/contrib/instrumentation/github.com/gin-gonic/gin/otelgin 

• Example
• Reference

Usage

You can instrument Gin router by installing OpenTelemetry middleware:

import ( "github.com/gin-gonic/gin" "go.opentelemetry.io/contrib/instrumentation/github.com/gin-gonic/gin/otelgin" ) router := gin.Default() router.Use(otelgin.Middleware("service-name")) 

Once your Gin application is instrumented with OpenTelemetry and telemetry data is exported, you can use observability tools compatible with your chosen OpenTelemetry backend to visualize distributed traces, analyze performance metrics, and gain insight into the behavior of your application.

Instrumenting templates rendering

To instrument templates rendering, use otelgin.HTML helper:

import "go.opentelemetry.io/contrib/instrumentation/github.com/gin-gonic/gin/otelgin" func exampleHandler(c *gin.Context) { otelgin.HTML(c, http.StatusOK, indexTmpl, gin.H{ "foo": "bar", }) } 

What is Uptrace?

Uptrace is a OpenTelemetry APM 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?

With Gin instrumentation configured, you can track HTTP requests, monitor performance bottlenecks, and correlate traces across your microservices. For database monitoring, check out GORM instrumentation or explore Echo framework for alternative web frameworks.
