Ever had a service “stick” while CPU, logs, and metrics all looked fine?

That’s when I grab sysdig — an X-ray for Linux that hooks syscalls and shows:

• who is reading/writing files 📂
• which connections are slow or stuck 🌐
• which processes actually burn CPU 🔥
• which containers misbehave 🐳

In my latest post I show:

• minimal install steps
• the short loop: capture → filter → view leaders → confirm with details
• 3 real-world scenarios: slow disk ops, sticky network, unclear CPU spikes
