I use Ubuntu as a test system, mainly for trying self-hosted apps that may bring my Raspberry Pi Zero to its knees. When you work with self-hosted apps, you tend to monitor their resource usage and fix problematic processes and services. Previously, Ubuntu’s default resource monitor, System Monitor, was my go-to tool. However, it had its fair share of pain points, ranging from a less configurable graph design to limited component graphs and missing service management options.
