Heartbeats for backups and jobs

1. Add a heartbeat

   On the Add page choose Heartbeat. Give it a name, such as Nightly backup, and choose how often it runs.

2. Copy its check-in address

   Open the heartbeat on the Overview page and tap Copy next to its check-in address. Keep it private, like a password.

   

3. Visit it when your job finishes

   Add one line to the end of your job, as in the examples below. Only visit it when the job worked.

Linux and Mac (cron)

0 2 * * * /usr/local/bin/backup.sh && curl -fsS -m 10 --retry 3 https://sitepatrol.app/hb/YOUR-CODE

The && means we only hear from it when the backup succeeds.

Windows (Task Scheduler or PowerShell)

Invoke-WebRequest -UseBasicParsing https://sitepatrol.app/hb/YOUR-CODE

In your own code

await fetch("https://sitepatrol.app/hb/YOUR-CODE");

A heartbeat is late after its usual gap plus a tenth, and always at least 5 minutes. A daily job is late after about 26 hours.
