The interface after connection is as follows

After connection, you can also use shortcut keys for interactive operation, and display commonly used shortcut keys according to different performances.

m : Sort processes by memory usage p : Sort processes by process name c : Sort processes by CPU usage i : Sort processes by I/O frequency a : Sort processes automatically d : Show/hide disk I/O statistics f : Show/hide file system statistics s : Show/hide sensor statistics y : Show/hide hard drive temperature statistics l : Show/hide logs n : show/hide network statistics x : delete warning and critical logs h : show/hide help q : exit w : delete warning logs

Finally, paste a performance monitoring chart by applying pressure to the host

Different colors will be displayed when the monitoring item reaches different thresholds. This is also explained in detail in the help. Press 'h' to enter the help interface.
