Go (Golang) is built for performance and reliability, often compiled into static binaries that run in containerized environments. Monitoring these binaries should be as efficient as the language itself.

olic.io acts as a dead man’s switch for your Go routines. You simply send a GET request to your unique monitor URL when your function completes. If the ping doesn’t arrive, we assume the binary crashed or hung.

Adding a Heartbeat to Your Go Program

Go’s standard library net/http is production-ready and requires no external packages.

Implementation

package main

import (
	"fmt"
	"net/http"
	"os"
	"time"
)

func main() {
	// Your unique olic.io URL
	heartbeatURL := "https://api.olic.io/ping/YOUR-ID-HERE"

	// --- YOUR CORE LOGIC HERE ---
	fmt.Println("Running database backup...")
	// ----------------------------

	// Send the success ping
	client := http.Client{
		Timeout: 10 * time.Second,
	}
	
	resp, err := client.Get(heartbeatURL)
	if err != nil {
		fmt.Printf("Failed to ping olic.io: %v\n", err)
		// Decide if this is a critical failure for your app
	} else {
		defer resp.Body.Close()
		fmt.Println("Ping sent to olic.io")
	}
}

Because Go is often used in microservices, you might have dozens of these running. You can organize them easily using Projects in your olic.io dashboard to keep production and staging monitors separate.

Why Golang for Backend Automation

Go is the language of the cloud. It is favored by SaaS teams for high-performance background workers, such as video processing or massive data aggregation.

Its strong concurrency model allows it to handle heavy loads, but that complexity can sometimes lead to race conditions or deadlocks. A cron monitor is essential here: it confirms that your binary didn’t just start, but actually finished its work. It’s the simplest way to run Healthchecks on your compiled tools.
