Field history tracking is a feature that allows you to monitor changes to certain fields on an object and display them in a history related list. Field history tracking can help you audit data quality, compliance, or business processes. Field history tracking cannot be configured from Schema Builder, but it can be configured from Object Manager. In Object Manager, you can select an object and enable field history tracking from its settings page. Then, you can choose up to 20 fields per object to track and add the history related list to the page layout.

Debug logs capture database operations, system processes, and errors that occur when executing a transaction or running unit tests. Debug logs can help identify the cause of Apex CPU time limit exceeded errors by showing the execution time of each Apex statement and trigger.
