Мониторинг I/O


decaz

Question

Возникла необходимость в понимании того, какие процессы обращаются к внешнему жесткому диску. В утилите htop во вкладке I/O повсюду значения "N/A",  утилита iotop не запускается:

~ # iotop
Could not run iotop as some of the requirements are not met:
- Linux >= 2.6.20 with
  - I/O accounting support (CONFIG_TASKSTATS, CONFIG_TASK_DELAY_ACCT, CONFIG_TASK_IO_ACCOUNTING)

Из документации к iotop: "At least the CONFIG_TASK_DELAY_ACCT, CONFIG_TASK_IO_ACCOUNTING, CONFIG_TASKSTATS and CONFIG_VM_EVENT_COUNTERS options need to be enabled in your Linux kernel build configuration.".

Нашел старый топик:

В нем сказано, что раньше такая возможность была, но в какой-то версии прошивки (ядра) она отвалилась. Вопрос: возможно ли ее вернуть?
