 ## Introduction

 ### Filtering
 
-For filtering out specific traces, `mendix.tracing.filter` system property can be used. The specified spans and their sub-spans will be filtered out. `matchType` specifies how the name of the span is matched. Currently only `partial` is supported for `matchType` which checks if the span name contains the provided value.

 ### Testing

+You can test the tracing you using [Jaeger](https://www.jaegertracing.io/). For example, you can use the all-in-one binary or Docker image. Jaeger will listen to endpoint `http://localhost:4318/v1/traces` by default.
 
 Alternatively, you can set up the [OpenTelemetry collector](https://opentelemetry.io/docs/collector/), which will also listen to the default endpoint and can be configured to send to backends which support OpenTelemetry. Check with your APM vendor to confirm that OpenTelemetry is supported. The free online collector configuration tool [OTelBin](https://github.com/dash0hq/otelbin) can help with collector configuration.
 
 ### All settings
 
-Below we list the ones that are supported by the Mendix runtime. See [Configure the SDK](https://opentelemetry.io/docs/languages/java/configuration/#environment-variables-and-system-properties) for a reference on the settings that are prefixed with `otel.`.

 ## Sending Traces to Datadog
 
-There are two options for exporting OpenTelemetry traces to Datadog: 
+You can export OpenTelemetry traces to Datadog using one of the following two ways: 
 
 * Datadog Distribution of OpenTelemetry (DDOT) 
 * OpenTelemetry Collector
 
 ### Datadog Distribution of OpenTelemetry (DDOT)
 
-DDOT can be deployed to Kubernetes or Linux (Preview). The default setup provides minimal configuration, allowing it to receive OpenTelemetry traces or logs from your Mendix app and send them to Datadog. With this default configuration, the collector listens on the same ports as your Mendix application.

 For installation instructions, refer to the official [DDOT documentation](https://docs.datadoghq.com/opentelemetry/setup/ddot_collector/install).
