Alerting on Cron Jobs That Finish Too Slow
Cron jobs are the unsung heroes of many systems. They handle everything from daily database backups and data synchronizations to report generation and cache invalidation. When they work, you barely notice them. When they fail, it's a problem. But what about when they don't fail, they just… slow down?
