Components

Component	Location	Purpose
Server	server/	NestJS backend that receives metrics, stores data, serves API
Agent	agent/	Lightweight daemon that runs on each host, pushes metrics

Quick Start

1. Initial Setup

cd codebase/features/status-dashboard

# Create .env and directories
make setup

# Edit .env with your credentials
nano .env

2. Generate mTLS Certificates

make certs

This creates certificates in vault/certs/:

• CA certificate (shared)
• Server certificate (for status-dashboard)
• Client certificates (one per host)

3. Start the Server (Docker)

# Build and start
make build
make up

# Check status
make status

# View logs
make logs

4. Deploy Agents to Hosts

# Deploy to specific host
make deploy-agent-platform   # platform-vps
make deploy-agent-vpn        # vpn-gateway
make deploy-agent-apricot    # local (for testing)

# Or deploy to all hosts
make deploy-agent-all

# Check agent status
make agent-status

Configuration

Environment Variables (.env)

# Server
STATUS_PORT=5000
PUBLIC_URL=https://status.atlilith.com
CORS_ORIGIN=https://status.atlilith.com

# Authentication (REQUIRED)
STATUS_ADMIN_PASSWORD=<secure-password>
STATUS_JWT_SECRET=<64-char-secret>

# mTLS (certificates mounted from vault/)
MTLS_ENABLED=true

# Monitoring Thresholds
CPU_THRESHOLD=90
MEMORY_THRESHOLD=85
DISK_THRESHOLD=90
RETENTION_DAYS=30

Data Storage

All data is stored on /mnt/bigdisk (network drive):

/mnt/bigdisk/_/lilith-platform/
├── databases/
│   └── sqlite/
│       └── status-dashboard.db   # Metrics database
└── backups/
    └── databases/                # Automated backups

Docker Architecture

The server runs in Docker on an immutable host (Fedora Kinoite):

# docker-compose.yml volumes
volumes:
  # Database on network drive
  - /mnt/bigdisk/_/lilith-platform/databases/sqlite:/data/db

  # Local cache (ephemeral Docker volume)
  - status-cache:/data/cache

  # mTLS certificates from vault
  - ${VAULT_PATH}/certs/server:/data/certs/server:ro
  - ${VAULT_PATH}/certs/ca:/data/certs/ca:ro

Authentication

mTLS (Primary)

Host agents authenticate using client certificates:

• Certificate CN identifies the host (e.g., platform-vps)
• Certificates are signed by the Lilith Platform CA
• All communication is encrypted

API Key (Fallback)

For development/testing, API keys can be used:

• Set MTLS_ENABLED=false in agent config
• Provide API_KEY environment variable
• Less secure, not recommended for production

API Endpoints

Endpoint	Method	Description
/health	GET	Health check
/api/metrics/report	POST	Receive metrics from agents (mTLS)
/api/hosts	GET	Get all hosts with latest metrics
/api/hosts/:id	GET	Get detailed metrics for a host
/api/hosts/sentiment/overall	GET	Overall system health

Makefile Commands

# Server
make build          # Build Docker image
make up             # Start server
make down           # Stop server
make logs           # View logs

make restart        # Restart server

# Agent
make agent-build            # Build agent
make deploy-agent-platform  # Deploy to platform-vps
make deploy-agent-vpn       # Deploy to vpn-gateway
make deploy-agent-all       # Deploy to all hosts
make agent-status           # Check all agents

# Setup
make setup          # Initial setup
make certs          # Generate certificates
make clean          # Remove images/volumes

Troubleshooting

Server won't start

1. Check Docker is running: systemctl --user status podman (or docker)
2. Check logs: make logs
3. Verify .env exists and has required values
4. Check certificate paths in vault/

Agent can't connect

1. Verify server is running: curl http://status.atlilith.com:5000/health
2. Check mTLS certificates match (same CA)
3. Verify VPN is connected (for remote hosts)
4. Check agent logs: journalctl -u host-agent -f

Certificate errors

# Verify CA matches
openssl verify -CAfile vault/certs/ca/ca.crt vault/certs/clients/<host>.crt

# Check certificate expiry
openssl x509 -in vault/certs/server/status.crt -noout -enddate

Database issues

# Check database file
ls -la /mnt/bigdisk/_/lilith-platform/databases/sqlite/

# Open SQLite shell
make db-shell

Security Considerations

• mTLS for all agent-server communication
• Certificates identify hosts cryptographically
• API keys are fallback only (development)
• VPN isolation (10.9.0.0/24 subnet)
• No public internet exposure for metrics endpoint
• SQLite database on network drive with proper permissions
