alerts

Build a lightweight, about 50-line Bash network monitor that pings key hosts, learns per-host latency baselines with EWMA, detects anomalies via sigma thresholds and packet loss, suppresses noise with consecutive checks, auto-captures mtr diagnostics, logs metrics to CSV, and alerts to a webhook; includes dependency setup, minimal config, full script, systemd/cron scheduling, plus tuning tips, examples, and troubleshooting.

This article on LinuxBash.sh demonstrates how to automate monitoring by setting up alerts and dashboards with Linux Bash. It details how IT administrators and DevOps engineers can use Bash scripts for proactive monitoring, including step-by-step instructions for gathering system metrics, scripting alerts, using `cron` for scheduling, and `gnuplot` for dashboards. This cost-effective method provides a customizable and lightweight alternative to costly monitoring tools.
