Description
The network-health-check script is used to automate diagnostics of network connectivity and performance. It combines a series of checks—such as ICMP pings to internal and external IPs, DNS resolution tests, gateway reachability, and port availability scans—to ensure that a system is properly connected and able to communicate.
This script is especially useful for servers or devices in environments where persistent uptime is critical. It helps detect common issues like dropped packets, failed DNS queries, or unreachable gateways. A well-crafted script of this type can also log historical uptime data, alert administrators when a threshold is breached, or even attempt automatic recovery actions like restarting the network interface or flushing DNS cache.
Many variants support email notifications, webhook integrations, or local system notifications, making them ideal for integration into monitoring systems. Additionally, some can compare latency against baseline metrics to detect degradation over time.
Regular use of network-health-check scripts helps ensure early detection of intermittent or creeping issues before they escalate into major outages. They’re commonly scheduled via cron jobs or used interactively for rapid troubleshooting by admins.
