This series of blog post will cover the installation and setup of a self-hosted Grafana-based observability stack. This stack will use OpenTelemetry to generate and collect logs, metrics, and traces, and tools from the Grafana ecosystem to visualize and analyze them. The use of OpenTelemetry allows for shipping logs to a different backend later on with hopefully minimal changes to the things that produce those logs. From the Grafana ecosystem, we will use the "LGTM" stack (Loki, Grafana, Tempo, Mimir), and Grafana Alerting.
