Monitor HTTPRouter in Go Applications with Atatus Go Agent

​

Installation steps

1. Install Atatus Go Agent and framework module
   go get go.atatus.com/agent
   go get go.atatus.com/agent/module/athttprouter
   
2. Set up tracer and add Atatus middleware
   import (
       "github.com/julienschmidt/httprouter"
       
       "go.atatus.com/agent"
       "go.atatus.com/agent/module/athttprouter"
   )
   
   func main() {
       // Initialize Atatus tracer with values from environment
       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")
   
       // Setup httprouter and wrap handlers with at instrumentation
       router := httprouter.New()
       const route = "/my/route"
       router.GET(route, athttprouter.Wrap(handleRequest, route))
   
       http.ListenAndServe(":8080", router)
   }
   
   
   func handleRequest(w http.ResponseWriter, r *http.Request, ps httprouter.Params) {
     // The context from r.Context() should be propagated to downstream operations,
     // such as database queries and external HTTP API calls
     
     ctx := r.Context()
     _ = db.QueryContext(ctx, "SELECT 'Atatus!'").Scan(&greeting)
   }
   
   Before running your application, make sure these environment variables are set in your terminal or .env file:
   export ATATUS_LICENSE_KEY=<your_atatus_license_key>
   export ATATUS_APP_NAME=<your_application_name>
   export ATATUS_TRACING=true
   export ATATUS_ANALYTICS=true
   export ATATUS_NOTIFY_HOST="YOUR_ON_PREMISE_URL"
   
3. Clean Up Dependencies
   go mod tidy
   
4. Run the Application
   go run main.go
