This document describes the local LGTM stack configured for this NixOS machine. The stack is managed declaratively by NixOS, runs as Podman containers under systemd, stores state on the host, and exposes service ports on localhost only.
LGTM means:
- Loki for logs.
- Grafana for dashboards, exploration, and datasource access.
- Tempo for traces.
- Mimir for metrics through the Prometheus-compatible API.
