# Tracing Sources

Tracing Service supports trace data from applications, services, SDKs, and collectors that can export OpenTelemetry traces.

{% hint style="info" %}
**Note:** You can send traces from any environment if your exporter can reach the service endpoint and is configured with the correct pipeline key.
{% endhint %}

Examples of supported tracing source categories include:

{% tabs %}
{% tab title="Application SDKs" %}
OpenTelemetry SDKs for languages such as Go, Java, Python, JavaScript, and .NET can instrument applications directly and export traces to the Tracing Service.
{% endtab %}

{% tab title="OpenTelemetry Collector" %}
The OpenTelemetry Collector can receive traces from multiple sources, batch them, and forward them to Tracing Service using `OTLP/HTTP` or `OTLP/gRPC`.
{% endtab %}

{% tab title="Service Mesh" %}
Ingress layers, proxies, or service meshes that emit OpenTelemetry-compatible traces can forward those traces to the Tracing Service for centralized analysis.
{% endtab %}

{% tab title="Custom Instrumentation" %}
Custom applications or frameworks that build OTLP trace payloads can export to the Tracing Service if they use the correct endpoint and `apikey` authentication.
{% endtab %}
{% endtabs %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.ionos.com/cloud/observability/tracing-service/overview/tracing-sources.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
