otop

CPUs, memory, GPUs and processes in the terminal, like btop, with the GPU detail of nvtop. On Linux and macOS.

• CPU: total use over time, and each CPU's use.
• Memory: RAM and swap, and RAM over time.
• GPUs: a panel for each, with utilisation and memory, and charts of both over time.
  • NVIDIA's, through NVML, loaded at run time from the driver (libnvidia-ml.so), so no CUDA toolkit is needed: temperature, P-state, power, fan, clocks, PCIe, encoder and decoder too.
  • Apple's, on macOS, from the IORegistry, without root.
  • Without either, otop runs without GPU panels.
• Processes: every process, with its user, CPU, memory, and for those on an NVIDIA GPU, which GPUs, GPU memory and SM use. Search them with /, and stop the one picked with k.

Install

cargo install otop

Use

otop             # sample every second
otop -d 500      # every 500 ms
otop --once      # print one sample as text, and exit
