The Java backend function uses [OpenTelemetry auto-instrumentation Java agent](../azure-monitor/app/opentelemetry-enable.md?tabs=java) to produce and export tracing data and correlated logs to the Application Insights instance.

By default, IoT Edge modules on the devices of the La Niña service are configured to not produce any tracing data and the [logging level](/aspnet/core/fundamentals/logging) is set to `Information`. The amount of produced tracing data is regulated by a [ratio based sampler](https://github.com/open-telemetry/opentelemetry-dotnet/blob/main/src/OpenTelemetry/Trace/TraceIdRatioBasedSampler.cs#L35). The sampler is configured with a desired [probability](https://github.com/open-telemetry/opentelemetry-dotnet/blob/bdcf942825915666dfe87618282d72f061f7567e/src/OpenTelemetry/Trace/TraceIdRatioBasedSampler.cs#L35) of a given activity to be included in a trace. By default, the probability is set to 0. With that in place, the devices don't flood the Azure Monitor with the detailed observability data if it's not requested.

We've analyzed the `Information` level logs of the `Filter` module and realized that we need to dive deeper to locate the cause of the issue. We're going to update properties in the `Temperature Sensor` and `Filter` module twins and increase the `loggingLevel` to `Debug` and change the `traceSampleRatio` from `0` to `1`:
