 ## Additional Information{#additional-info}
 
+### Log Levels (`DD_LOG_LEVEL`){#log-levels}
+
+`DD_LOG_LEVEL` controls the verbosity of Datadog agent logs. Use it solely for [troubleshooting Datadog agent](https://docs.datadoghq.com/agent/troubleshooting/debug_mode/) issues.
+
+To control which logs are published to your APM tools, configure the settings on the [Log Levels](/developerportal/operate/monitoring-with-apm/#tuning-log-levels) tab. 
+
 ### Datadog Regions (`DD_SITE`){#dd-regions}
 
 By default, the Datadog integration defaults to the US region (`datadoghq.com`). If you want to use a Datadog site that is in another region, go to the [Custom Environment Variables](/developerportal/deploy/environments-details/#custom-environment-variables) section of your Mendix app environment and add a `DD_SITE` custom environment variable. Set the variable's value to the relevant site. For example, for the EU Datadog site, set `DD_SITE` to `datadoghq.eu`.
