How to Monitor Go Cron Jobs with CronRabbit

Go

The Problem

Go binaries running on a cron schedule can panic, deadlock, or exit silently. Without monitoring, failures go undetected until someone notices stale data.

The Solution

Make an HTTP GET request to CronRabbit at the end of your Go program. If the ping doesn't arrive on schedule, you get an alert.

Why Monitor Go Cron Jobs?

Go programs are compiled binaries — there's no runtime to catch panics for you. A nil pointer dereference, goroutine leak, or network timeout can crash the binary silently. CronRabbit watches for the expected ping and alerts you if it's missing.

Integration Steps

Create a monitor in CronRabbit matching your cron schedule. Add an http.Get() call at the end of your main() function. Use defer for cleanup and send /fail on errors.

Code Examples

Basic heartbeat ping

Go
package main

import (
	"log"
	"net/http"
	"time"
)

const pingURL = "https://ping.cronrabbit.com/your-id"

func main() {
	client := &http.Client{Timeout: 10 * time.Second}

	// Signal start
	client.Get(pingURL + "/start")

	if err := runJob(); err != nil {
		client.Get(pingURL + "/fail")
		log.Fatal(err)
	}

	// Signal success
	client.Get(pingURL)
}
