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.

Log Pipeline #

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

1. 1. Log Source

   Add configuration to discover and read `/var/log/myapp/*.log` files.

2. 2. Log Processing

   Add a processing block to dynamically add an `env=production` label to all collected log lines.

3. 3. Dispatching to Loki

   Configure sending logs to a Loki instance available at `http://localhost:3100`.
