Self-hosted, no paid SaaS. Host/container/Postgres metrics, uptime probes against the new /healthz endpoints, alert rules split critical (pages) vs warning (informational), one starter Grafana dashboard. Deliberately separate from the application's instructor learning analytics (Phase 3B) - different audience, different data. Validated: promtool check config (valid), promtool check rules (11 rules, valid), amtool check-config (1 inhibit rule, 2 receivers, valid).

# Promtail on rn-lab-host-01 — same shape as promtail-config.platform.yml, but pushes to Loki

# over the network (Loki lives on rn-platform-01, not locally) since these two hosts don't
|
|
# share a Docker network. {{ platform_ip }} is an Ansible variable, rendered by the lab-host

|
# role — see infra/firewall/rn-platform-01.rules for the matching inbound rule (3100, this

# host's IP only).
