LGTM Observability Stack

• What it is: A full LGTM monitoring stack (Loki/Grafana/Tempo/Mimir-Prometheus) for a production Ubuntu server: metrics, logs, traces, visualization, alerts — with automatic collection from every Docker container. Part of the healthcare-platform (health) infrastructure.
• Type / status / role: infra (observability/DevOps) / maintained / solo — all 6 commits authored by Davron Yuldashev.
• Activity period: 2025-11-04 (one day, 6 commits) — a fast but complete and well-documented setup.

• Languages: YAML (configs), Shell (scripts).
• Components (docker-compose): Prometheus 2.48 (metrics), Loki 2.9 (logs), Tempo 2.3 (distributed tracing), Grafana (visualization), Promtail (logs agent), node-exporter (host metrics), cAdvisor (container metrics). Networks lgtm/monitoring, named volumes, health checks.
• Infra: Docker Compose (5.3 KB), nginx reverse proxy for Grafana (HTTP + TLS variants), import-dashboards.sh, Grafana provisioning (datasources + dashboards automatically).
• Configs: configs/{loki,promtail,tempo,prometheus,grafana} — loki-config, promtail-config, tempo.yaml, prometheus.yml + alerts.yml, Grafana provisioning. 30-day retention.
• Dashboards: dashboards/ — docker-logs-dashboard.json, docker-logs-advanced.json (+ README).

Solo, 6 commits in a single day — a full turnkey observability stack:

• Compose orchestration of 7 services (Prometheus/Loki/Tempo/Grafana/Promtail/node-exporter/cAdvisor) with volumes/networks/health checks.
• Auto-collection: Promtail pulls logs from all Docker containers, cAdvisor — container metrics, node-exporter — host.
• Grafana provisioning (datasources + dashboards) + dashboard-import script.
• nginx reverse proxy (HTTP + TLS configs) for secure access to Grafana.
• Prometheus alerts (alerts.yml), 30-day retention.
• Rich documentation: README 23 KB (with ASCII architecture), LOGS_DASHBOARDS_GUIDE.md 13 KB, NGINX_SETUP.md.

Confirmed by configs/compose/README.

• Full turnkey LGTM stack → metrics + logs + traces + visualization in one compose with auto-discovery of all containers (Promtail + cAdvisor). Understanding of modern observability (3 pillars: metrics/logs/traces).
• Grafana provisioning-as-code → datasources and dashboards come up automatically (provisioning + import script), not via UI clicks. IaC approach.
• Secure access → nginx reverse proxy with a TLS variant, Grafana auth, network isolation (separate docker networks).
• Alerting + retention → Prometheus alert rules, 30-day retention across all components.
• This is config/IaC, not application code — but well-built, production-ready and reusable.

• Sessions found: 0 (no matches for the full key). A local .claude/ exists (settings).
• What was done with AI: no data (no transcripts).
• AI-workflow patterns: none.

• 7-service observability stack (LGTM + exporters) turnkey in 1 day.
• 3 pillars of observability (metrics/logs/traces) + alerts + 30-day retention.
• Grafana provisioning-as-code + 2 pre-built dashboards + nginx TLS proxy.
• ~45 KB of documentation (README + 2 guides).
