Set Up Debug Logging
To activate debug logging for users, Apex classes, and Apex triggers, configure trace flags and debug levels in the Developer Console or in Setup. Each trace flag includes a debug level, start time, end time, and log type. The trace flag’s log type specifies the entity you’re tracing.

- To create a trace flag, click Add.
- To edit an existing trace flag’s duration, double-click its start or end time.
- To change a trace flag’s debug level, click Add/Change in the Debug Level Action column. You can then edit your existing debug levels, create or delete a debug level, and assign a debug level to your trace flag. Deleting a debug level deletes all trace flags that use it.
