nvtop command

NAME¶

nvtop - NVIDIA GPU top

SYNOPSIS¶

nvtop [-hv] [-si id1:id2:...] [-d delay]

nvtop is a ncurses-based GPU status viewer for NVIDIA GPUs.

-d, --delay=delay: Delay between updates, in tenths of seconds (delay * 0.1s).
-h, --help: Print the help and exit.
-s, --gpu-select=id1:...: Colon separated list of GPU IDs to be monitored by nvtop.
-i, --gpu-ignore=id1:...: Colon separated list of GPU IDs to be ignored by nvtop.
-C, --no-color: Monochrome mode.
-N, --no-cache: Disable the (process id, user name, command line) cache and query the system at each refresh.
-f, --freedom-unit: Use fahrenheit as temperature scale.
-E, --encode-hide=seconds: Modify the setting for the encode/decode auto-hide timer. Always visible if negative. Default to 30 seconds.
-r, --reverse-abs: Reverse abscissa: switch the plot data order from "old --- recent" (default) to "recent --- old".
-p, --no-plot: Show only one bar plot corresponding to the maximum of all GPUs.
-v, --version: Print the version and exit.

The following commands are available while in nvtop:
Up: Select (highlight) the previous process.
Down: Select (highlight) the next process.
Left / Right: Scroll in the process row.
+: Sort increasingly.
-: Sort decreasingly.
F9: "Kill" process: Select a signal to send to the highlighted process.
F6: Sort: Select the field for sorting. The current sort field is highlighted inside the header bar.
F10, q, Esc: Quit.

When the video encoder (ENC) and decoder (DEC) of the GPU are in use, new percentage meters will appear next to the GPU utilization bar. They will disappear automatically after some time of inactivity (see option -E).

Some fields are shown as N/A: Ask NVIDIA for better support of your hardware!
Compatibility issues: Does not work with nouveau driver stack and older NVIDIA GPU for the time being.
