How does Healthchecks know a job failed?
Each check has a ping URL your job calls when it finishes, plus a period and a grace time. When no ping arrives inside that window, the check goes late or down and Healthchecks sends the alerts.
Healthchecks: Cron Job and Task Monitoring
Waiting for a cron job to fail silently is how a backup stops running for weeks. Point each job at a ping URL, and the cron job monitoring server alerts you when the ping does not arrive in time. Email, Slack, Discord, Telegram and a webhook are among the alert channels.
