Process & Resource Monitoring (Top/Htop/Ps/Systemd)

Stop systemd-cgtop from guessing where your resource hog is hiding

🧩 The Challenge

Finding out which specific service is devouring your RAM is a nightmare when standard tools just show a sea of PIDs. I’ve wasted half a morning digging through random processes only to realize a background slice was the real culprit.

💡 The Fix

Use systemd-cgtop to view your resource usage grouped by control groups instead of individual tasks. It makes it dead obvious which slice or service is actually misbehaving.

systemd-cgtop -d 1

⚙️ Why It Works

This utility hooks directly into the cgroup hierarchy to aggregate metrics, so you see the total impact of a service rather than chasing down individual child processes. You’ll finally see the entire tree at once.

🚀 Pro-Tip: Press ‘k’ to sort by memory or ‘c’ for CPU to flip between views in real-time.
