🚀 Quick Start

1. Access Monitoring

# Grafana Dashboard
open https://grafana.pressmess.duckdns.org
# Login: admin / admin123

# Prometheus Metrics
open https://prometheus.pressmess.duckdns.org

2. Check Service Health

# View all monitoring targets
curl "http://192.168.50.229:9091/api/v1/targets"

# Check system metrics
curl "http://192.168.50.229:9091/api/v1/query?query=up"

3. Monitor System Resources

# CPU Usage
curl "http://192.168.50.229:9091/api/v1/query?query=100%20-%20(avg%20by%20(instance)%20(irate(node_cpu_seconds_total{mode=\"idle\"}[5m]))%20*%20100)"

# Memory Usage
curl "http://192.168.50.229:9091/api/v1/query?query=(1%20-%20(node_memory_MemAvailable_bytes%20/%20node_memory_MemTotal_bytes))%20*%20100"
