Where Does radeontop Store Readings?
radeontop readings on Linux, live TUI plus dump files since no config exists.
Last updated
radeontop reads AMD GPU counters live and keeps no config file. Every run starts fresh from kernel counters. Dumps go wherever you redirect them.
Treat invocations as the config. Save dump commands with intervals and bus selection. The tool suits quick checks more than long archives.
Where radeontop stores this, by platform
/sys/class/drm/card0/device/gpu_busy_percent
No config file exists upstream. Redirect dumps to dated files. Check render node permissions when output stays blank.
Frequently asked questions
How do I log radeontop stats?
Run radeontop with --dump-interval and redirect to a dated file. The TUI itself stores nothing. Keep the command line in a script for repeats.
Why is radeontop blank?
Confirm the AMD card binds amdgpu and the user can read the render nodes. Root clarifies permission versus driver issues. Old r600 era cards show less.
