name	system-check
description	Check system status — repos, services, containers, APIs. Use when you need to verify system health or diagnose issues.

System Check — Status Diagnostics

Run diagnostics on your system components. Adapt the commands to your infrastructure.

Quick checks

API health

curl -s --max-time 5 "http://${DND_VPS_IP:-localhost}:${DND_VPS_PORT:-3002}/api/status" \
  -H "X-Auth-Token: ${DND_API_TOKEN}"

Service status

# Check if your main service is running
systemctl is-active ${DND_SERVICE_NAME:-my-service} 2>/dev/null || echo "Service not found"

Container health (if using Docker)

docker ps --filter "name=${DND_CONTAINER_NAME:-my-container}" --format "{{.Names}}: {{.Status}}"

Container logs

docker logs ${DND_CONTAINER_NAME:-my-container} --tail 20 2>&1

Interpreting results

• status: online — API responding
• Up X minutes (healthy) — container running with health check passing
• EACCES — file ownership issue (docker cp creates root-owned files)

Environment variables

Configure these in your .env or shell profile:

• DND_VPS_IP — your server IP (default: localhost)
• DND_VPS_PORT — API port (default: 3002)
• DND_API_TOKEN — authentication token
• DND_CONTAINER_NAME — Docker container name
• DND_SERVICE_NAME — systemd service name
