Function mprober::process::get_processes_with_cpu_utilization_in_percentage

pub fn get_processes_with_cpu_utilization_in_percentage(

) -> Result<Vec<(Process, f64), Global>, ScannerError>

Get process information by reading files in the /proc/PID folders and measure the cpu utilization in percentage within a specific time interval. If the number it returns is 1.0, means 100%.
