database monitoring

Build AI-powered DB monitoring from the Linux shell: Bash collects PostgreSQL counters, a tiny Python script converts them to per‑second rates and uses Isolation Forest to learn baselines and flag anomalies, and a wrapper posts throttled alerts to Slack/webhooks via cron. Includes apt/dnf/zypper install steps, venv setup, tuning tips, and is easily extended to MySQL/MariaDB/MongoDB.
