part8: Writing Traces to Tempo with Grafana Alloy

Hello everyone. In the eighth part of the Grafana LGTM Stack course, we will first focus on Grafana Alloy and use its components to receive traces from the application we deployed via OpenTelemetry and send them to the tracing backend, which is Tempo. We will also learn how to add new metadata to the resource attributes of each span using Grafana Alloy components and even how to generate metrics from spans. We will get familiar with the NodeGraph and ServiceGraph, configure them, and see how they help us identify the relationships between services and even the spans of a single trace. In this part, we will also link trace data to logs.
