Hi Zach, Seeing the `fs perf stats` output , it looks like you are not using the latest build. Lots of enhancements are being done in cephfs-top recently. Will suggest to use latest build for better results. And regarding your `use_default_colors()` error, it looks like there some issue with the unsupported terminal emulator.
