Я хочу показать, сколько ЦП используется с течением времени.
Используя системный монитор, я могу показать загрузку процессора, но только 4 отдельных ядра. Я хочу иметь возможность показать график общего использования процессора.
Другими словами, ядро ЦП 1+2+3+4 = всего, всего <- график
Вы можете использовать conky, чтобы сделать это.
Conky - это приложение, которое рисует наложение на вашем рабочем столе, показывая различную системную информацию. Вы можете настроить то, что показано, создав файл ".conkyrc" в вашем домашнем каталоге.
Это файл .conkyrc, который я использую (это модифицированная версия файла в PartedMagic):
# the list of variables has been removed from this file in favour
# of keeping the documentation more maintainable.
# Check http://conky.sf.net for an up-to-date-list.
# set to yes if you want Conky to be forked in the background
background yes

Я придумал способ получить общее число использования процессора, которое вы можете затем построить график:
echo print `top -n 1 | tr -s " " | cut -d$" " -f10 | tail -n +8 | head -n -1 | paste -sd+ | bc`/ `nproc` | python
