top, htop, btop and nvtop: Linux monitoring compared

This Russian-language overview compares Linux console monitors by the problems they help diagnose and the resources their interfaces consume. It starts with ps snapshots and kill signals, then explains how top refreshes a process table at regular intervals.

The comparison separates live inspection from historical investigation. The speaker presents atop as a background recorder for examining activity before a server failure, including disk load and processes that disappear between screen refreshes. htop adds colored CPU bars, memory indicators and mouse interaction. Glances covers broader system metrics and can expose them through a web interface, but the speaker warns that its own workload can be noticeable on weaker machines.

PowerTOP shifts the focus to laptop power consumption and tuning recommendations. The discussion of bashtop, bpytop and btop follows the author's successive rewrites, with the speaker crediting btop with better responsiveness while retaining graphical terminal displays.

For local AI workloads, nvtop is the most directly relevant tool discussed. The speaker describes GPU clock, video memory and temperature metrics, plus a process list for identifying programs consuming graphics resources. This is a monitoring comparison rather than an installation guide or a measured performance benchmark.
