-Azure Monitor Application Insights Distro uses the OpenTelemetry API Logger for internal logs. To enable it, use the following code:
-
-```typescript
-import { ApplicationInsightsClient, ApplicationInsightsConfig } from "applicationinsights";
-import { DiagLogLevel } from "@opentelemetry/api";
-
-const appInsights = new ApplicationInsightsClient(new ApplicationInsightsConfig());
-const logger = appInsights.getLogger();
-logger.updateLogLevel(DiagLogLevel.DEBUG);
-```
-
 
 `APPLICATIONINSIGHTS_INSTRUMENTATION_LOGGING_LEVEL` environment varialbe could be used to set desired log level, supporting the following values: `NONE`, `ERROR`, `WARN`, `INFO`, `DEBUG`, `VERBOSE` and  `ALL`.
