[TP] Hands-on: Collecting and Dispatching Logs to Loki

Introduction #

The goal of this lab is to configure Grafana Alloy to read local log files, add context labels, and send them to a Grafana Loki instance.

We will configure the blocks composing the pipeline in River language.

1. Log Source
Add configuration to discover and read `/var/log/myapp/*.log` files.
2. Log Processing
Add a processing block to dynamically add an `env=production` label to all collected log lines.
3. Dispatching to Loki
Configure sending logs to a Loki instance available at `http://localhost:3100`.
