We are excited to announce that Heartbeat checks are now in General Availability.

Increase reliability and confidence by effortlessly monitoring your backup jobs, database updates, imports, and other recurring tasks with our latest check type.

With GA, heartbeat checks have an updated UI and are fully supported on Checkly, including in our analytics API, dashboards, maintenance windows, and more.

Create private or public dashboards for your users or teams to showcase your backend status. Plan your upgrades without worrying about false alerts, and import run data into your analytics platform.

Getting started

Heartbeat checks await pings from external sources, with each check having a unique URL the job pings when successful. This ping URL be can be added to a wide variety of jobs. Here is a simple example of adding a heartbeat ping to any bash cron job scheduled in your crontab:

# run_backup.sh

PING_URL=https://api.checklyhq.com/heartbeats/ping/4e4e488a-76bc-46b0-9a55-7799997ed139

curl -m 5 --retry 3 $PING_URL;

And if you are using node:

const axios = require('axios');

axios.get('https://ping.checklyhq.com/87c05896-3b7d-49ae-83ff-5e81323a54c4').then(resp => {
    console.log(resp.data);
})

Unsure of how to add a ping event to your scheduled job? Our documentation covers multiple programming and scripting languages, getting you started in no time.

Looking for help?

Heartbeat checks are available on the following plans:

  • Team with a quota of 15 Heartbeat checks.

  • Enterprise with a custom quota.

New

You can now define three distinct retry strategies for API checks, browser checks and check groups. Each strategy, Fixed, Linear or Exponential has different backoff characteristics to cover different retrying scenarios.

You can also toggle if retries are performed from the initial failing location, or from a different location picked from your configured check locations.

With this new feature, you can reduce alert fatigue and increase the signal vs. noise level of alert messages.

Check out our updated documentation for more details.

You can configure your retry strategies also via:

This feature is available on all plans except for plans marked as "deprecated"

CLI version v4.1.0 just came out and provides support for the new smart retry strategies we just released. Adding a retry strategy is simple. Just use the RetryStrategyBuilder and add it to any ApiCheck, BrowserCheck or CheckGroup construct.

import { ApiCheck, RetryStrategyBuilder } from 'checkly/constructs'

new ApiCheck('retrying-check-01', {
  name: 'ACME API production',
  retryStrategy: RetryStrategyBuilder.linearStrategy({
    baseBackoffSeconds: 30,
    maxRetries: 4,
    sameRegion: false,
  }),
  request: {
    method: 'GET',
    url: 'https://danube-web.shop/api/books'
  }
})


Read more about smart retries and retry strategies on our changelog.


Further enhancements and fixes include:

  • HeartbeatCheck 's now print their ping URL to the console on creation.

  • HeartbeatCheck's are now part of our advanced example repo.

  • Various bugfixes on timeouts and typos.

To get started with the Checkly CLI just run

npm create checkly 

Or upgrade your existing installation with

npm install checkly@latest

New

Checkly now supports both IPv4 and IPv6, also called dual stack. This means that we can reach both IPv4 and IPv6 addresses from our check runtime.

Note that for most workloads (API checks, browser checks, etc.) the IPv6 stack is automatically preferred over IPv4 if available. This means that if your endpoint is reachable over IPv6, we will use that. If not, we will fall back to IPv4.

For Browser checks, you can instruct the Chrome instance to actually prefer IPv4. Have a look at our docs for a code example on how to achieve that.

Note that browser checks still using Puppeteer are not running on our dual stack infra as we are deprecating Puppeteer support.


IPv6 is automatically enabled and available on all plans.

Improved


We have updated our default user agent to use Chrome instead of HeadlessChrome.

This makes check runs more closely replicate the actual user experience and reduces the likelihood of checks being blocked by bot filters or firewalls.

The new user agent uses the following format: "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.4951.53 Safari/537.36 (Checkly, https://www.checklyhq.com)"

If you have used the user agent definition to allowlist browser checks, please replace HeadlessChrome with Chrome in any firewall settings.

New

You can now export any supported resource directly to a Checkly CLI compatible TypeScript construct or a Terraform manifest directly from the web UI. This new feature makes it a ton easier to start adopting a monitoring as code workflow using the Checkly CLI or our Terraform provider.

The exporter works with API checks, browser checks, groups, alert Channels, maintenance windows, dashboards, private locations and environment variables!

For checks using snippets or setup & teardown scripts, we inline the code into a fresh file and reference it in the resource saving you a ton of copy and paste work.

Just hit the Export to code button and of you go.

The exporter is available on all plans.

With the new Activity Log, you can now see the origin of any Checkly resource: who created it or updated it, when and by what method: Web UI, CLI, public API, Terraform or Pulumi.

This new feature makes it a ton easier to keep track of your monitoring as code workflow, especially when using the Checkly CLI. With the CLI integration, you can track extra git metadata so you have access to repo, branch and commit info right in the UI. Check our docs on how to set this up.

This feature is available on all plans with a 7 day data retention for Hobby plans and 30 days for Team plans and standard 180 days for Enterprise.
