Introduction #

What you will learn in this section

• Configure the otlphttp exporter
• Generate traces
• Query them

Context. Your applications are instrumented with OpenTelemetry. You route them through a Collector, without tying them directly to the platform.

Prerequisites: the previous lab  ·  Estimated time: 35 min

An end-to-end trace flow.

Setup #

Guided steps, with their solution.

1. 1. Configure the Collector

   Why? The exporter appends /v1/traces itself: only set the base.

   Write collector.yaml with the otlphttp exporter and the authentication header.

2. 2. Add the Collector to the stack

   Why? The password must not be written in the Collector configuration.

   Add the collector service to the Compose file.

3. 3. Generate traces

   Why? telemetrygen stands in for an instrumented application.

   Start the stack and send 20 traces to the Collector.

4. 4. Check

   Why? The stream-name header selected the applis stream.

   Query the stream of type traces, then open the Traces menu in the UI.
