How Heartbeat Monitoring Works
Your service sends periodic pings. We alert you if they stop.
Create a Monitor
Set up a heartbeat monitor with your expected check-in interval
Send Heartbeats
Your service pings the unique URL at regular intervals
Get Alerted
We notify you immediately if a heartbeat is missed
import { Kodo } from 'kodo-sdk';
const kodo = new Kodo({ apiKey: process.env.KODO_API_KEY });
// Send a heartbeat every minute
setInterval(async () => {
await kodo.heartbeat('queue-worker');
}, 60_000);
// Or ping after each job
worker.on('job:complete', async () => {
await kodo.heartbeat('queue-worker');
});Monitoring Made Simple
Everything you need for reliable heartbeat monitoring
Heartbeat Endpoints
Unique ping URLs for each service. Just hit the URL to signal that your service is alive.
Missed Beat Alerts
Get notified immediately when a service misses its expected heartbeat check-in.
Internal Services
Perfect for services that can't be monitored externally — workers, queues, and background jobs.
Any Language
Send a simple HTTP request from any language or platform. No SDK required.
Sub-Minute Intervals
Configure check-in intervals from 30 seconds to days. Match your service's requirements.
Auto-Recovery Detection
Automatically detect when services recover and update status accordingly.
Perfect For
Any service that needs to phone home
Background Workers
Monitor Sidekiq, Celery, or any queue processor
worker.on('complete', () => kodo.heartbeat('worker-1'))Scheduled Tasks
Verify cron jobs and scheduled tasks complete successfully
curl https://ping.kodo.status/abc123Internal APIs
Monitor services behind firewalls that can't be pinged externally

Keep tabs on ETL jobs, data pipelines, and batch processes

Frequently Asked Questions
Heartbeat monitoring is a way to monitor services that can't be pinged from the outside. Your service sends periodic 'heartbeat' signals. If we don't receive a heartbeat within the expected time, we alert you.
