`sudo jetson_clocks` I see `jtop`, but it’s inactive. ---

hello AlfredNG, instead of using `jtop`. could you please execute [tegrastats utility](https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3261/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/AppendixTegraStats.html#) and share the reports before/after running `jetson_clocks`. thanks ---
