# Telemetry Processing

Telemetry from all the Lern Components are pushed in to Sunbird-Obsrv data-pipeline through "{env}.telemetry.raw" Kafka topic using Logstash.

Please refer the Subird-Obsrv documentation for more details:

Data-pipeline Flow Diagram:&#x20;

Lern services like UserOrg, LMS, Groups and Notification Service push the telemetry to Raw Kafka in below diagram, so telemetry extractor flink job and ingest router flink job does not come in to action. Those two jobs are application in case of UI components, where telemetry service API is called to push telemetry events.

## 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://lern.sunbird.org/use/learn-more/telemetry-processing.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.
