...but things fail all the time. It's how you respond that makes the difference. Get real time and contextful alerts on any channel you want, and find out when your service fails before your customers do.

Full control over your alerts

The internet can be flaky. A failing service might be fine two seconds later. Avoid false positives by specifying exactly when you should be alerted and how often you want to be reminded.

alerts.check.ts
import { SmsAlertChannel } from '@checkly/cli/constructs'

const smsChannel = new SmsAlertChannel('sms-channel-1', {
  // receive recovery notifications
  sendRecovery: true,
  // receive failure notifications
  sendFailure: true,
  // receive degraded notifications [API checks only]
  sendDegrade: true,
  // receive a notification when a SSL/TLS certificate expires [API check only]
  sslExpiry: true,

  phoneNumber: '0031061234567890',
})

Pick your channels

Choose one or more of the available alerting channels. We have everything from email, to Pagerduty, Opsgenie, and SMS. And if you need something custom, use custom webhooks or hook up our Prometheus integration to roll out your alerting.

Alert channels: phone, mail, SMS, webhooks, Pageduty, Splunk, MS team, GitLab, Slack

About our webhooks...

We take webhooks very seriously. That's why we give you complete control over the webhook payload to hook up Checkly's alerts to basically any system out there.

webhook.check.ts
import { WebhookAlertChannel } from '@checkly/cli/constructs'

const webhookChannel = new WebhookAlertChannel('webhook-channel-1', {
  name: "Pushover webhook",
  method: "POST",
  url: "https://api.pushover.net/1/messages.json",
  template: `{
    "token":"FILL_IN_YOUR_SECRET_TOKEN_FROM_PUSHOVER",
    "user":"FILL_IN_YOUR_USER_FROM_PUSHOVER",
    "title":"{{ALERT_TITLE}}",
    "html":1,
    "priority":2,
    "retry":30,
    "expire":10800,
    "message":"{{ALERT_TYPE}} {{STARTED_AT}} ({{RESPONSE_TIME}}ms) {{RESULT_LINK}}"
  }`
})
