Scheduled jobs are basically background transactions that don't concern user. Basic tasks like data collection, data archiving, and alerting are some common examples. These tasks may get frequently executed at regular intervals. 

Since these tasks take place in the background, it's easier to overlook any issues or errors arising from them.  Often you won't know if these transactions are successful or not unless a major issue erupts and bogs down your entire application. This is why monitoring background transactions is essential for quickly debugging errors.

You can monitor your background transactions by editing APM Insight agent configurations. Tracking key metrics like traces or CPU consumption for each transaction can help you stay proactive. 

Happy monitoring!
