+Scheduled jobs or cron jobs are crucial for automating tasks, but failures can lead to major problems if undetected. MaC enables [heartbeat monitoring](https://www.checklyhq.com/blog/heartbeat-monitoring-with-checkly/) to ensure these jobs run on schedule.
 
 A heartbeat check verifies that a job reports back within the expected timeframe. If it doesn’t, an alert is triggered, giving you a chance to fix the issue before it impacts your system.

 When [retries are set up correctly](https://www.checklyhq.com/docs/alerting-and-retries/), we should only get a synthetic transaction monitoring alert when there’s a real problem that users will notice. But detecting an issue through synthetic monitoring is only the first step. Pinpointing the root cause of problems requires additional diagnostic tools and processes. Synthetic monitoring should be run as a separate service from all of your internal services and tools, and as such will lack insight into how your back end is handling requests. Once you’ve detected a problem, backend logs, traces, and other information from something like an [OpenTelemetry monitoring system](https://www.checklyhq.com/learn/opentelemetry/getting-started-with-observability/), will be needed to find a root cause.
