Key Features

• Automated Discovery: Randomized ICMP sweeps across multiple subnets to automatically find new devices.
• Real-Time Monitoring
• Optional SNMP Enrichment
• InfluxDB Integration: Native support for InfluxDB v2, separating operational metrics from health telemetry.
• Secure Deployment: Native systemd installation supports rootless execution via capability-based security (CAP_NET_RAW), while Docker orchestration simplifies local evaluation.
