# Local observability stack for FineCode OpenTelemetry development.
#
# All services are gated behind the "otel" Compose profile, so they stay DOWN
# by default — including when the devcontainer auto-starts. Opt in either way:
#   - Persistent:  set COMPOSE_PROFILES=otel in .env, then (re)open the devcontainer.
#   - On demand:   scripts/observability.sh up   (see that script for down/status).
# Standalone (outside the devcontainer):
#   docker compose --profile otel -f docker-compose.otel.yml up -d
#
# Set the WM telemetry endpoint (workspace config otlp_endpoint, default
# http://otel-lgtm:4317) to also stream live signals to the collector; WAL
# events are captured regardless and can be ingested retroactively.

services:
  # Bundles the OTel Collector, Tempo, Prometheus, Loki, and Grafana in one
  # container (grafana/otel-lgtm). We run our own collector config inside it
  # (mounted over its default) so the WAL->Loki pipeline (ADR-0039) and the
  # Tempo<->Loki correlation wiring are preserved; everything else (storage
  # engines, Grafana, dashboards) is otel-lgtm's own bundled build.
  #
  # otel-lgtm's Tempo/Prometheus/Loki are only reachable from *inside* this
  # container (127.0.0.1:4418/9090/3100) — see configs/otel/collector.yaml
  # and the datasource provisioning for those internal endpoints. The image
  # tag is pinned because those internal endpoints are not a stable public
  # contract.
