observability-control（可观测性控制）

Observability Control

Manage the lifecycle of the observability stack for Claude Code telemetry.

Stack Locations

Components

Operations

start

Start observability stack.

docker compose -f /mnt/c/data/github/botaniqal-medtech/botaniqal-medtech/observability/docker-compose.yml up -d

stop

Stop stack gracefully (preserves data).

docker compose -f /mnt/c/data/github/botaniqal-medtech/botaniqal-medtech/observability/docker-compose.yml down

restart [service]

Restart specific service or all services.

# Restart all
docker compose -f /path/docker-compose.yml restart

# Restart specific
docker restart loki

status

Health check all components.

docker ps --format "table {{.Names}}\t{{.Status}}" | grep -E "(otel|loki|grafana|prometheus|tempo)"

Output: Running services, health status.

health

Verify service endpoints.

curl -s http://localhost:3000/api/health  # Grafana
curl -s http://localhost:9090/-/healthy   # Prometheus
curl -s http://localhost:3100/ready       # Loki
curl -s http://localhost:3200/ready       # Tempo

backup

Export dashboards and configurations.

# Backup dashboards
curl -s http://localhost:3000/api/search -u admin:admin | \
  jq -r '.[].uid' | \
  xargs -I {} curl -s http://localhost:3000/api/dashboards/uid/{} -u admin:admin > backup/dashboards.json

Output: .observability/backups/YYYYMMDD_HHMMSS/

restore <backup-path>

Restore from backup.

curl -X POST http://localhost:3000/api/dashboards/db \
  -H "Content-Type: application/json" \
  -u admin:admin \
  -d @backup/dashboards.json

logs [service]

View logs from stack components.

docker logs loki --tail 100
docker logs otel-collector --tail 100
docker logs grafana --tail 100

fix-permissions

Fix volume permission issues (common with Tempo).

docker volume rm observability_tempo-data
docker volume create observability_tempo-data
docker run --rm -v observability_tempo-data:/tempo alpine chown -R 10001:10001 /tempo
docker restart tempo

Quick Commands

# Check all services status
docker ps | grep -E "(otel|loki|grafana|prometheus|tempo|promtail)"

# View recent logs for issues
docker logs otel-collector --tail 50 2>&1 | grep -i error

# Test OTLP endpoint
curl -v http://localhost:4317

# Query Loki for recent data
curl -s "http://localhost:3100/loki/api/v1/labels"

# List Grafana dashboards
curl -s http://localhost:3000/api/search -u admin:admin | python3 -c "import sys,json; [print(d['title']) for d in json.load(sys.stdin)]"

Troubleshooting

OTEL Collector Unhealthy

docker logs otel-collector --tail 30
# Common fix: Ensure Prometheus has --web.enable-remote-write-receiver

Loki Unhealthy

docker logs loki --tail 30
# Common fix: Disable frontend_worker for single-node mode

Tempo Permission Denied

# Fix volume permissions
docker volume rm observability_tempo-data
docker volume create observability_tempo-data
docker run --rm -v observability_tempo-data:/tempo alpine chown -R 10001:10001 /tempo
docker restart tempo

No Data in Grafana

1. Check telemetry env vars: env | grep OTEL
2. Check hooks configured: cat.claude/settings.json
3. Verify Loki receiving: curl "http://localhost:3100/loki/api/v1/labels"
