log_monitor()    { sudo tail -f /var/log/syslog | grep --line-buffered -E "(error|warning|critical)" | while read line; do echo "$(date): ALERT - $line"; done; }

### Performance Trending
perf_trend()     { sar -u 1 5 | tail -5; } # CPU trending over 5 seconds
mem_trend()      { sar -r 1 5 | tail -5; } # Memory trending
disk_trend()     { sar -d 1 5 | tail -5; } # Disk I/O trending
