In the Monitoring page, you can select the ID of the Scenario Execution to access the Detailed Log.
Once the ID is selected, you can see the logs of selected scenario execution under Detailed Log.

The log level can be configured for each scenario. Select the desired Log Level under Advanced Settings before saving and activating the scenario. This can be changed on the Edit page of the scenario when re-running the scenario.

On the Setting tab, you can select the log level, which will be the default value on all Integration Scenarios, unless otherwise specified on that particular Integration Scenario.
