Loki Configuration
In this lab, you will learn how to ship and query logs. You will configure and run Promtail, the log collection agent, add Loki as a data source in Grafana, and then query your logs using the LogQL language. The setup provides running instances of Loki and Grafana.
Docker
Grafana Installation
In this lab, you will install Grafana using Docker. You will learn how to run the Grafana container, access its web UI, and connect it to a pre-existing Prometheus instance as a data source, preparing you to build powerful monitoring dashboards.
Docker
PromQL Basics
In this lab, you'll explore the Prometheus Query Language (PromQL). Using a pre-configured Prometheus and Node Exporter setup, you will learn to query and manipulate time-series data, from basic selections to applying functions and filters.
