About:
Sntop is a command-line utility that continuously polls multiple hosts to monitor network connectivity and availability. It uses a curses-based interface to display real-time status updates, allowing users to quickly identify which hosts are online or offline. This tool is valuable for network administrators and developers who need to monitor servers or services without setting up complex monitoring infrastructure.

Key Features:

Real-time curses-based interface for continuous monitoring
Supports polling multiple hosts simultaneously
Displays historical uptime/downtime statistics
Simple command-line configuration
Lightweight and low system resource usage

Use Cases:

Monitoring server uptime across a network infrastructure
Verifying connectivity to remote services during development
Tracking intermittent network connectivity issues
Quickly checking if multiple websites or APIs are responding

Alternatives:

ping – Standard ICMP tool, monitors single hosts without a persistent interface
mtr – Combines traceroute and ping, focuses on network path analysis rather than multi-host monitoring
nagios – Enterprise monitoring solution with extensive features but requires significant setup
