Monitor Echo v4 in Go Applications with Atatus Go Agent

Installation Steps For Echo 4.x

If you are using Echo 4.x (github.com/labstack/echo/v4), use module/atechov4.

Install Atatus Go Agent and framework module

copy
```
go get go.atatus.com/agent
go get go.atatus.com/agent/module/atechov4
```

Set up tracer and add Atatus middleware

copy

import (
    "github.com/labstack/echo/v4"

    "go.atatus.com/agent" 
    "go.atatus.com/agent/module/atechov4"
)

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 (atechov4)
    e.Use(atechov4.Middleware())
}

func handleRequest(c echo.Context) error {
    // The context from c.Request().Context() should be propagated to downstream operations,
    // such as database queries and external HTTP API calls

    // Example 
    ctx:=c.Request().Context()
    _ = db.QueryContext(ctx, "SELECT 'Atatus!'").Scan(&greeting)
}

Clean Up and Sync Dependencies

copy
```
go mod tidy
```
