Monitor Echo v3 in Go Applications with Atatus Go Agent

​

Installation Steps For Echo 3.x

1. Install Atatus Go Agent and framework module
   go get go.atatus.com/agent
   go get go.atatus.com/agent/module/atecho
   
2. Set up tracer and add Atatus middleware
   import (
       "github.com/labstack/echo"
   
       "go.atatus.com/agent"
       "go.atatus.com/agent/module/atecho"
   )
   
   func main() {
       // Initialize Atatus tracer using environment variables
       tracer := atatus.DefaultTracer
       tracer.Service.LicenseKey = os.Getenv("ATATUS_LICENSE_KEY")
       tracer.Service.AppName = os.Getenv("ATATUS_APP_NAME")
       tracer.Service.Tracing = os.Getenv("ATATUS_TRACING")
       tracer.Service.Analytics = os.Getenv("ATATUS_ANALYTICS")
   
       e := echo.New()
       
       // Setup echo router and apply Atatus middleware (atecho)
       e.Use(atecho.Middleware())
       
       e.GET("/", handleRequest)
   
       // Start server
       e.Fatal(e.Start(":8080"))    
   }
   
   func handleRequest(c echo.Context) error {
       ctx:= c.Request().Context() // c.Request().Context() should be propagated to downstream operations such as database queries, http external API calls.
   
       // Example 
       _ = db.QueryContext(ctx, "SELECT 'Atatus!'").Scan(&greeting)
   }
